PART IIANSWERS TO END-OF-CHAPTER QUESTIONSCHAPTER 14: INTERNATIONAL LOGISTICS14-1. Discuss some of the key political restrictions on cross-border trade.Political restrictions on cross-border trade can take a variety of forms. Many nations ban certain types of shipments that might jeopardize their national security. Likewise, individual nations may band together to pressure another country from being an active supplier of materials that could be used to build nuclear weapons. Some nations restrict the outflow of currency because a nation,s economy will suffer if it imports more than it exports over a long term. A relatively commonpolitical restriction on trade involves tariffs, or taxes that governments place on the importation of certain items. Another group of political restrictions can be classified as nontariff barriers, which refer to restrictions other than tariffs that are placed upon imported products. Another political restriction involves embargoes, or the prohibition of trade between particular countries.14-2. How might a particular country,s government be involved in international trade?Governments may exert strong control over ocean and air traffic because they operate as extensions of a nation,s economy and most of the revenue flows into that nation's economy. In some cases, import licenses may restrict movement to a vessel or plane owned or operated by the importing country. In addition, some nations provide subsidies to develop and/or maintain their ocean and air carriers. Governments also support their own carriers through cargo preference rules, which require a certain percentage of traffic to move on a nation,s flag vessels. Although federal governments have often owned ocean carriers and international airlines, some government-owned international carriers are moving toward the private sector.14-3. Discuss how a nation,s market size might impact international trade and, in turn,international logistics.Population is one proxy for market size, and China and India account for about one-third of the world's population. As such, these two countries might be potentially attractive markets because of their absolute and relative size. Having said this, India has a relatively low gross domestic product per capita, and because of this some customers buy singleuse packets of products called sachets. From a logistical perspective, single-use packets require different packaging, and are easier to lose and more prone to theft than products sold in larger quantities.14-4. How might economic integration impact international logistics?Potential logistical implications of economic integration include reduced documentation requirements, reduced tariffs, and the redesign of distribution networks. For example,Poland and the Czech Republic have become favorite distribution sites with the eastward expansion of the European Union.14-5. How can language considerations impact the packaging and labeling of international shipments?With respect to language, cargo handlers may not be able to read and understand the language of the exporting country, and it would not be unusual for cargo handlers in some countries to beilliterate. Hence, cautionary symbols, rather than writing, must be used. A shipper,s mark, which looks like a cattle brand, is used in areas where dockworkers cannot read but need a method to keep documents and shipments together.14-6. What is a certificate of origin, a commercial invoice, and a shipper,s export declaration?A certificate of origin specifies the country or countries in which a product is manufactured .This document can be required by governments for control purposes or by an exporter to verify thelocation of manufacture. A commercial invoice is similar in nature to a domestic bill of lading in the sense that a commercial invoice summarizes the entire transaction and contains (or should contain) key information to include a description of the goods, the terms of sale and payment, the shipment quantity, the method of shipment, and so on. A shipper,s export declaration contains relevant export transaction data such as the transportation mode(s), transaction participants, and a description of what is being exported.14-7. Discuss international terms of sale and Incoterms.International terms of sale determine where and when buyers and seller will transfer 1) the physical goods; 2) payment for goods, freight charges, and insurance for the in-transit goods; 3) legal title to the goods; 4) required documentation; and 5) responsibility for controlling or caring for the goods in transit. The International Chamber of Commerce is in charge of establishing, and periodically revising, the terms of sale for international shipments, commonly referred to as Incoterms. The most recent revision, Incoterms 2010, reflects the rapid expansion of global trade with a particular focus on improved cargo security and new trends in cross-border transportation. Incoterms 2010 are now organized by modes of transport and the terms can be used in both international and domestic transportation.14-8. Name the four methods of payment for international shipments. Which method is riskiest for the buyer? For the seller?Four distinct methods of payment exist for international shipments: cash in advance, letters of credit, bills of exchange, and the open account. Cash in advance is of minimal risk to the seller, but is the riskiest for the buyer-what if the paid-for product is never received? The open account involves tremendous potential risk for the seller and minimal risk for the buyer.14-9. Discuss four possible functions that might be performed by international freight forwarders.The text describes eight functions, such as preparing an export declaration and booking space on carriers, so discussion of any four would be appropriate.14-10. What is an NVOCC?An NVOCC (nonvessel-operating common carrier) is often confused with an international freight forwarder. Although both NVOCCs and international freight forwarders must be licensed by the Federal Maritime Commission, NVOCCs are common carriers and thus have common carrier obligations to serveand deliver, among other obligations. NVOCCs consolidate freight from different shippers and leverage this volume to negotiate favorable transportation rates from ocean carriers. From the shipper's perspective, an NVOCC is a carrier; from an ocean carrier,s perspective, an NVOCC is a shipper.14-11. What are the two primary purposes of export packing?One function is to allow goods to move easily through customs. For a country assessing duties on the weight of both the item and its container, this means selecting lightweight packing materials. The second purpose of export packing is to protect products in what almost always is a more difficult journey than they would experience if they were destined for domestic consignees.14-12. Discuss the importance of water transportation for international trade.A frequently cited statistic is that approximately 60 percent of cross-border shipments move by water transportation. Another example of the importance of water transportation in international trade involves the world,s busiest container ports as measured by TEUs (twenty-foot equivalent units) handled; 9 of the 10 busiest container ports are located in Asia, with 7 of the busiest ports located in China.14-13. Explain the load center concept. How might load centers affect the dynamics of international transportation?Load centers are major ports where thousands of containers arrive and depart each week. As vessel sizes increase, it becomes more costly to stop at multiple ports in a geographic area, and as a result, operators of larger container ships prefer to call at only one port in a geographic area. Load centers might impact the dynamics of international trade in the sense that some ports will be relegated to providing feeder service to the load centers.14-14. Discuss the role of ocean carrier alliances in international logistics.In the mid-1990s, ocean carrier alliances, in which carriers retain their individual identities but cooperate in the area of operations, began forming in the container trades. These alliances provide two primary benefits to participating members, namely, the sharing of vessel space and the ability to offer shippers a broader service network. The size of the alliance allows them to exercise considerable clout in their dealings with shippers, port terminal operators, and connecting land carriers.14-15. How do integrated air carriers impact the effectiveness and efficiency of international logistics?Integrated air carriers own all their vehicles and the facilities that fall in-between. These carriers often provide the fastest service between many major points. They are also employed to carry the documentation that is generated by—and is very much a part of— the international movement of materials. The integrated carriers also handle documentation services for their clients.14-16. How do open-skies agreements differ from bilateral agreements?Bilateral agreements generally involved two countries and tended to be somewhat restrictive in nature. For example, the bilateral agreements would specify the carriers that were to serve particular city pairs. By contrast, open skies agreements liberalize aviation opportunities andlimit federal government involvement. For example, the Open Aviation Agreement between the United States and 27 European Union (EU) member states allows any EU airline as well as any U.S. airline to fly between any point in the EU and any point in the United States.14-17. Discuss the potential sources of delays in certain countries with respect to motor carrier shipments that move across state borders.One source of delays is that certain countries limit a motor carrier,s operations to within a particular state,s borders; as a result, multi-state shipments must be transferred from one company,s vehicle to another company,s vehicle whenever crossing into another state. Another source of delays is that certain countries conduct inspections of trucks as they move from one state to another. This can include physical counting and inspection of all shipments, inspection of documentation, and vehicle inspection, as well as driver inspection.14-18. Define what is meant by short-sea shipping (SSS), and discuss some advantages of SSS.Short-sea shipping (SSS) refers to waterborne transportation that utilizes inland and coastal waterways to move shipments from domestic ports to their destination. Potential benefits to SSS include reduced rail and truck congestion, reduced highway damage, a reduction in truck-related noise and air pollution, and improved waterways utilization.14-19. What are some challenges associated with inventory management in cross-border trade?Because greater uncertainties, misunderstandings, and delays often arise in international movements, safety stocks must be larger. Furthermore, inventory valuation on an international scale isdifficult because of continually changing exchange rates. When a nation,s (or the world's) currency is unstable, investments in inventories rise because they are believed to be less risky than holding cash or securities.Firms involved in international trade must give careful thought to their inventory policies, in part because inventory available for sale in one nation may not necessarily serve the needs of markets in nearby nations. Product return policies are another concern with respect to international inventory management. One issue is that, unlike the United States where products can be returned for virtually reason, some countries don,t allow returns unless the product is defective in some respect.14-20. What is the Logistics Performance Index? How can it be used?The Logistics Performance Index (LPI) was created in recognition of the importance of logistics in global trade. The LPI measures a country,s performance across six logistical dimensions:•Efficiency of the clearance process (i.e., speed, simplicity, and predictability of formalities) by border control agencies, including customs;•Quality of trade- and transport-related infrastructure (e.g., ports, railroads, roads, and information technology);•Ease of arranging competitively priced shipments;•Competence and quality of logistics services (e.g., transport operators and customs brokers);•Capability to track and trace consignments;•Timeliness of shipments in reaching the destination within the scheduled or expected delivery time.The LPI is a potentially valuable international logistics tool because the data can be analyzed from several different perspectives. First, the LPI can be analyzed for all countries according to the overall LPI score as well as according to scores on each of the six dimensions. Second, the LPI can be analyzed in terms of an individual country's performance over time, relative to its geographic region, and relative to its income group.PART IIICASE SOLUTIONSCASE 14-1: Nurnberg Augsburg Maschinenwerke (N.A.M.)Question 1: Assume that you are Weiss. How many viable alternatives do you have to consider regarding the initial shipment of 25 buses?The answer to this question can vary depending on how students define “viable alternatives.” If we take a broad perspective and just focus on the primary cities, Bremerhaven does not appear to be an option because there is no scheduled liner service in the desired time frame. That leaves us with Prague to Santos through Hamburg and Prague to Santos through Rotterdam. Several of the vessel departure dates for both alternatives are not feasible. For example, the 18-day transit time from Hamburg eliminates both the October 31 and November 3 departures; likewise, the 17-day transit time from Rotterdam eliminates the November 2 departure. And although the October 27 departure from Hamburg or the October 28 departure from Rotterdam should get the buses to Santos by November 15, neither departure leaves much room for potential transit delays (e.g., a late season hurricane). As such, it appears that Weiss has but two viable alternatives: the October 24 departure from Hamburg and the October 23 departure from Rotterdam.Question 2: Which of the routing alternatives would you recommend to meet the initial 90-day deadline for the 25-bus shipment? Train or waterway? To which port(s)? What would it cost?If one assumes that rail transport is used from Prague to either Hamburg or Rotterdam, then thetotal transportation costs of the two alternatives are virtually identical. Although rail costs to Rotterdam are €300 higher than to Hamburg, the shipping costs from Rotterdam are €300 lower than from Hamburg (based on €6000 x .95). Because the total transportation costs are essentially the same, the decision likely needs to be based on service considerations. The initial shipment is extremely important. It might be suggested that Prague to Hamburg by rail and Hamburg to Santos by ocean vessel is the preferred alternative. Our rationale is that the provided transit times with Hamburg are definitive— that is, 3 days by rail and 18 days by water. With Rotterdam, by contrast, the rail transit time is either 4 or 5 days, although water transportation is 17 days.Question 3: What additional information would be helpful for answering Question 2?A variety of other information would be helpful for answering Question 2. For example, the case offers no insight about port congestion issues and how this congestion might impact the timeliness of shipment loadings. There also is no information about port performance in terms of loss and damage metrics. In addition, although the case indicates that rail transit time from Prague iseither four or five days, it might be helpful to know what percentage of shipments is completed in four days. Students are likely to come up with more suggestions.Question 4: How important, in fact, are the transport costs for the initial shipment of 25 buses?Clearly, with ocean shipping costs of either €5700 or €6000 per bus, transportation costs cannot be ignored. Having said this, the initial shipment holds the key to the remainder of the order (another 199 buses) and appears to be instrumental in securing another order for 568 buses (for a total of 767 more buses). As such, N.A.M might be somewhat flexible with respect to transportation costs for the initial shipment. Suppose, for example, that N.A.M. can earn a profit of €5000 per bus (such profit on a €120000 bus is by no means exorbitant). A profit of €5000 x 767 buses yields a total profit of €3,835,000. Because of such a large upside with respect to additional orders,N.A.M. might focus on achieving the specified metrics for the initial shipment without being overly concerned with transportation costs.Question 5: What kinds of customer service support must be provided for this initial shipment of 25 buses? Who is responsible?Although a number of different constituencies is involved in the initial shipment (e.g., railroads, dock workers, ocean carrier, etc.), the particular customers—the public transit authorities—are buying product from N.A.M. Because of this, N.A.M. should be the responsible party with respect to customer service support. There are myriad customer service support options that might be provided. Real-time shipment tracking should be an option so that the customers can know, at any time, the location of the shipment. N.A.M. might also provide regular updates of shipment progress; perhaps N.A.M. could email or fax important progress points (e.g., the shipment has left Prague; the shipment has arrived in Hamburg, etc.) to the customers. Because successful performance on theinitial shipment is crucial to securing future business, N.A.M. might have one of its managers actually accompany the shipment.Question 6: The Brazilian buyer wants the buses delivered at Santos. Weiss looks up theInternational Chamber of Commerce,s Incoterms and finds three categories of “delivered” terms:DAT (Delivered at Terminal). In this type of transaction, the seller clears the goods forexport and bears all risks and costs associated with delivering the goods and unloading them at the terminal at the named port or place of destination. The buyer is responsible for all costs and risks from this point forward including clearing the goods for import at the named country of destination.DAP (Delivered at Place). The seller clears the goods for export and bears all risks and costs associated with delivering goods to the named place of destination not unloaded. The buyer is responsible for all costs and risks associated with unloading the goods and clearing customs to import goods into the named country of destination.DDP (Delivered Duty Paid). The seller bears all risks and costs associated with delivering the goods to the named place of destination ready for unloading and clearing for import.How should he choose? Why?Again, given the importance of the initial shipment, it would appear that the more control thatN.A.M. has over the process, the better. Although the DDP option is likely the costliest option, it also affords N.A.M. more control later into the shipment process. Moreover, a willingness by N.A.M. to take on the additional costs associated with DDP might be viewed in a positive fashion by the customers.Question 7: Would you make the same routing recommendation for the second, larger (199 buses) component of the order, after the initial 90-day deadline is met? Why or why not?Time pressures do not appear to be as critical for the larger component of the order, so this might argue for use of water transportation between Prague and Hamburg. The rationale would be that even though water transportation is slower, it saves money (€48 per bus) over rail shipments. Alternatively, given that the selling price per bus is likely to be around €120000, trading off three days of transit time in exchange for a savings of €48 might not be such a good idea.Question 8:How important, if at all, is it for N.A.M. to ship via water to show its support of the European Union,s Motorways of the Seas concept?This question may generate a variety of opinions from students. For example, some students might argue that Question 75s answer also applies to Question 8. Having said this, the case doesn,t delve too deeply into potential environmental considerations associated with water transportation, so a pure cost-benefit analysis (such as Question 7) might be insufficient. Furthermore, because the European Union (EU) continues to be a contentious issue for many Europeans, the answer to Question 8 might depend upon one,s view of the EU. Thus, someone who is supportive of the EU might lean toward supporting the Motorways of the Seas concept, while someone not supportive of the EU might lean against supporting the Motorways of the Seas concept.。

财务会计英文版课后习题答案Ch12
CHAPTER 12 DISCUSSION QUESTIONS1.There are several reasons for a firm to makeinvestments in assets not directly related to the primary operations of its business (that is, investments in assets other than property, plant, equipment, and inventory). Companies usually make short-term investments be-cause of a temporary surplus of cash. They make long-term investments either because they believe that purchased investments provide a good return on money invested or because they want to gain influ-ence or control over investee companies.2.The risk and return trade-off of investmentsis that investors must usually decide whether they want a potentially higher return with more risk or a lower return with less risk.Most investments fall somewhere along a risk-return continuum. Investments that pro-vide high returns but have low risk are desir-able, but rare.3.The FASB has defined four different classifi-cations for debt and equity securities: trading securities, available-for-sale securities, held-to-maturity securities, and equity method se-curities.4. A security will be classified as trading if theinvestor is making the investment with the intent of selling the security should the need for cash arise, or to realize short-term profits should the price of the security increase.5. A security will be classified as held-to-maturity if the investor intends to hold the security until it matures. This criterion means that only debt securities can be classified as held-to-maturity, as equity securities typically do not mature. If a debt security is classified as held-to-maturity, any premium or discount associated with the security must be amor-tized over the life of the debt security.6.To be classified as an equity method securi-ty, an investor must typically own between20 and 50% of the outstanding commonstock of the investee. Ownership of between20 and 50% generally indicates the ability ofthe investor to significantly influence the operations and decisions of the investee.7.When an investor purchases debt and equitysecurities, two types of returns may be rea-lized. The first type of return is the receipt ofinterest (in the case of debt) or dividends (inthe case of equity). The second type of re-turn is from an increase in the price of thesecurity. To realize this type of return, the in-vestor must sell the security.8.When a security is sold, the seller must haveseveral pieces of information to properly ac-count for the transaction. The seller mustknow the selling price as well as the histori-cal cost of the security. The differencebetween these two amounts results in a rea-lized gain or loss on the sale.9.The difference between a realized gain orloss and an unrealized gain or loss relates tothe account ing concept of arm’s-lengthtransactions. The term ―realized‖ indicatesthat an arm’s-length transaction has takenplace and a security has been sold. A rea-lized gain indicates that the security was soldfor more than its historical cost, while a rea-lized loss means that the security was soldfor less than its original purchase price. Anunrealized gain means that the price of thesecurity being held has increased above itshistorical cost, but the security has not beensold. If the security is still being held and theprice falls below its historical cost, an unrea-lized loss has occurred.10.The account ―Market Adjustment‖ is used tovalue both trading and available-for-sale se-curities at their market value. Trading andavailable-for-sale securities are initiallyrecorded at their historical cost, and as theirvalue changes, the historical cost remainsthe same on the books. To reflect marketvalues on the books, the market adjustmentaccount is used to record both increasesand decreases in value. A separate marketadjustment account is used for both tradingand available-for-sale securities.11.Changes in the value of trading securities,both increases and decreases, are recordedon the books of the investor. Prior to 1994,only declines below historical cost wererecorded on the books. In 1994, however,434Chapter 12the rules were changed to allow companiesto record both increases and decreases invalue. At the end of each accounting period,the market value of the portfolio of tradingsecurities is compared to its historical cost,and the difference is recorded in the marketadjustment account. The offsetting credit (inthe case of increases in value) or debit (inthe case of decreases in value) is recordedin an income statement account as an un-realized gain or loss.12.Accounting for changes in the value ofavailable-for-sale securities is similar to theprocedures applied when accounting fortrading securities with one important differ-ence. Instead of recording any unrealizedincreases or decreases in value on theincome statement, unrealized increasesand decreases in value are recorded in astockholders’ equity account, UnrealizedIncrease/Decrease in Value of Available-for-Sale Securities—Equity. Thus, the journalentry to record unrealized changes in valuealways contains the stockholders’ equity a c-count and the market adjustment—available-for-sale securities account.13.The market adjustment account can befurther adjusted; however, the adjustmentaccount should always report the total netchange in the value of the security. For ex-ample, if a security that cost $200 rose invalue to $300 during the first period and thento $350 during the second period, the mar-ket adjustment account would show a bal-ance of $150 at the end of the second period. 14.Premiums and discounts on available-for-sale securities are not amortized because itis assumed that trading and available-for-sale securities will not be held long enoughto warrant the need to amortize a premiumor discount.15.Changes in the value of held-to-maturity andequity method securities are not accountedfor on the books of the investor. For held-to-maturity securities, the investor intends tohold the debt security until it matures, and asa result, changes in value will not affectthe eventual maturity value of the security.For equity method securities, the investoris holding the security for the purpose ofbeing able to influence the operating deci-sions of the investee on a long-term basis.Thus, temporary changes in value of equitymethod securities are ignored for accountingpurposes.16.The only difference between the accountingfor trading securities and available-for-salesecurities lies in unrealized changes in valueof those securities. For trading securities,the changes in value are recorded on the in-come statement. For available-for-sale se-curities, the unrealized changes in value arerecorded in a stockholders’ equity a ccount. 17.*When buying a held-to-maturity security, aninvestor purchases the right to receive twodifferent types of future cash receipts. First,the investor receives periodic interest pay-ments over the life of the security; second,the investor receives the face amount (prin-cipal) of the security at maturity.18.* A company would usually be willing to paymore than the face amount (a premium) fora held-to-maturity security when the interestrate on the security is higher than the marketrate of interest for similar investments. Thepaying of a higher price reduces the statedrate of interest to a point where it approx-imates the market rate of interest.19.*The amortization of a discount increases theamount earned on a held-to-maturity securitybecause at maturity investors receive theface value, which is higher than the amountoriginally paid. These increased proceedsmust be recognized over the life of the secu-rity through amortization. The amortization ofa discount increases interest from a statedrate to a higher effective rate.20.*An investor purchasing held-to-maturitysecurities (typically bonds) between interestdates must pay for accrued interest becauseat the next interest payment date a fullpe riod’s interest will be received, eventhough the securities have been held for onlya portion of the period. Because the securi-ties are sold in relatively small denomina-tions and are usually owned by numerousindividuals, it is almost impossible for acompany to know who bought how manybonds on which dates. Therefore, with manyheld-to-maturity securities, whoever ownsthe securities on the interest payment datereceives the full period’s i nterest.*Relates to expanded material.Chapter 12 43521.*The effective-interest amortization method istheoretically superior to the straight-lineamortization method because it takes intoconsideration the time value of money. Withthe effective-interest method, the amount ofinterest recognized is the effective interestrate times the amount of money actuallybeing borrowed at any period of time. Thestraight-line method is only an approximationof the true rate of interest.22.*The key criterion for using the equity methodis the ability of the investor to influence theoperations or decisions of the investee.23.*The accounting profession has providedguidelines to determine if the ability tosignificantly influence the operating deci-sions of an investee exists. The primaryguideline is degree of ownership. If the in-vestor owns between 20 and 50% of a cor-poration’s outstanding common stock, it isassumed that the investor is able to signifi-cantly influence the investee. Thus, unlessevidence exists to the contrary, ownership ofbetween 20 and 50% would require the useof the equity method.24.* When an investor purchases a trading secu-rity, revenue is recognized when interest ordividends are received. A gain or loss (un-re alized) is recorded when the security’sprice changes in value. For an investmentaccounted for under the equity method, rev-enue is recognized when the investee re-ports income for the period. This recognitionserves to increase the investment ac-count. The investment account is decreasedwhen dividends are received from the inves-tee. Unlike trading securities, temporarychanges in the value of equity method secur-ities are not recorded on the investor’sbooks.25.* Consolidated financial statements are pre-pared when a corporation owns more than50% of the stock of another company (acontrolling interest).26.* In the consolidated balance sheet, minorityinterest is the amount of equity investmentmade by outside shareholders to consolidat-ed subsidiaries that are not 100% owned bythe parent. In the consolidated incomestatement, minority interest income (shownas a subtraction) reflects the amount ofincome belonging to outside shareholders ofconsolidated subsidiaries that are not 100%owned.*Relates to expanded material.436Chapter 12PRACTICE EXERCISESPE 12–1 (LO1) Why Companies Invest in Other CompaniesThe correct answer is B.a. True. Most cases of companies investing in other companies are to investexcess cash.b. False. Investing in other companies will not necessarily eliminate risk in oth-er investments.c. True. By investing in other companies, the investing company can gain in-fluence over the operations of another company.d. True. When one company owns a significant portion of another company,the owner company can essentially control the operations of the owned company.PE 12–2 (LO2) Classifying a SecurityThe correct answer is C. Held-to-maturity securities are always considered debt securities. Trading and available-for-sale securities can sometimes be consi-dered debt securities. True to their name, equity method securities are always considered equity securities.PE 12–3 (LO2) Equity Method SecuritiesThe correct answer is A. An entity is presumed to have significant influence upon the operations of another company when it owns 20 to 50% of the outstanding voting stock.PE 12–4 (LO2) Disclosure of SecuritiesThe correct answers are A and C. Equity method securities are valued at cost ad-justed for changes in the net assets of the investee.

The Properties of Solids and Liquids
The Properties of Solids and Liquids IntroductionThe world around us is full of different types of matter. Everything we interact with, from the clothes we wear to the food we eat, is made up of matter. The two most common states of matter we encounter in our daily lives are solids and liquids. In this article, we will explore the properties of these two states of matter and how they differ from each other.Properties of SolidsSolids are defined as materials that have a fixed shape and volume. The particles in a solid are tightly packed together and have a fixed position relative to each other. This means that solids have a definite shape and cannot be compressed easily.One of the main characteristics of solids is their rigidity. When a force is applied to a solid, it tends to resist deformation and maintain its shape. This is because the particles in a solid are held together by strong intermolecular forces.Another important property of solids is their density. Solids have a high density because their particles are tightly packed together. This means that solids are typically heavier than liquids or gases of the same volume.Other properties of solids include their ability to conduct heat and electricity. Metals are good conductors of both heat and electricity because their electrons are free to move throughout the solid. Non-metallic solids, on the other hand, are poor conductors of both heat and electricity because their electrons are tightly bound to their atoms.Properties of LiquidsLiquids are defined as materials that have a fixed volume but not a fixed shape. The particles in a liquid are close together but have more freedom to move relative to each other than the particles in a solid. This means that liquids take the shape of their container.One of the main characteristics of liquids is their ability to flow. When a force is applied to a liquid, it will deform and flow to fill any available space. This is because the particles in a liquid have enough energy to move around but not enough energy to break apart from each other.Another important property of liquids is their surface tension. This is the force that holds the surface of a liquid together. Surface tension is created by the attractive forces between the particles in a liquid. The surface tension of a liquid can be measured by the force required to break its surface.Other properties of liquids include their ability to dissolve other substances. Liquids that dissolve other substances are called solvents. Water is a common solvent and is able to dissolve a wide range of substances. The ability of a liquid to dissolve another substance depends on the chemical properties of both the solvent and the solute.ConclusionIn conclusion, solids and liquids have different properties that make them useful for different applications. Solids have a fixed shape and volume, are rigid, and conduct heat and electricity well. Liquids have a fixed volume but not a fixed shape, flow, and dissolve other substances. Understanding the properties of solids and liquids is important in fields such as materials science, chemical engineering, and physics.。

Part 2 Chapter 12_2
Part 2 Chapter 12WHY THE PEASANTS FLOCK TO TOWN.The prison was a long way off and it was getting late, so Nekhludoff took an isvostchik. The isvostchik, a middle-aged man with an intelligent and kind face, turned round towards Nekhludoff as they were driving along one of the streets and pointed to a huge house that was being built there."Just see what a tremendous house they have begun to build," he said, as if he was partly responsible for the building of the house and proud of it. The house was really immense and was being built in a very original style. The strong pine beams of the scaffolding were firmly fixed together with iron bands and a plank wall separated the building from the street.On the boards of the scaffolding workmen, all bespatteredwith plaster, moved hither and thither like ants. Some were laying bricks, some hewing stones, some carrying up the heavy hods and pails and bringing them down empty. A fat andfinely-dressed gentleman--probably the architect--stood by the scaffolding, pointing upward and explaining something to a contractor, a peasant from the Vladimir Government, who was respectfully listening to him. Empty carts were coming out of the gate by which the architect and the contractor were standing, and loaded ones were going in. "And how sure they all are--those that do the work as well as those that make them do it--that it ought to be; that while their wives at home, who are with child, are labouring beyond their strength, and their children with the patchwork caps, doomed soon to the cold grave, smile with suffering and contort their little legs, they must be building this stupid and useless palace for some stupid anduseless person--one of those who spoil and rob them," Nekhludoff thought, while looking at the house."Yes, it is a stupid house," he said, uttering his thought out aloud."Why stupid?" replied the isvostchik, in an offended tone. "Thanks to it, the people get work; it's not stupid.""But the work is useless.""It can't be useless, or why should it be done?" said the isvostchik. "The people get bread by it."Nekhludoff was silent, and it would have been difficult to talk because of the clatter the wheels made.When they came nearer the prison, and the isvostchik turned off the paved on to the macadamised road, it became easier to talk, and he again turned to Nekhludoff."And what a lot of these people are flocking to the townnowadays; it's awful," he said, turning round on the box and pointing to a party of peasant workmen who were coming towards them, carrying saws, axes, sheepskins, coats, and bags strapped to their shoulders."More than in other years?" Nekhludoff asked."By far. This year every place is crowded, so that it's just terrible. The employers just fling the workmen about like chaff. Not a job to be got.""Why is that?""They've increased. There's no room for them.""Well, what if they have increased? Why do not they stay in the village?""There's nothing for them to do in the village--no land to be had."Nekhludoff felt as one does when touching a sore place. Itfeels as if the bruised part was always being hit; yet it is only because the place is sore that the touch is felt."Is it possible that the same thing is happening everywhere?" he thought, and began questioning the isvostchik about the quantity of land in his village, how much land the man himself had, and why he had left the country."We have a desiatin per man, sir," he said. "Our family have three men's shares of the land. My father and a brother are at home, and manage the land, and another brother is serving in the army. But there's nothing to manage. My brother has had thoughts of coming to Moscow, too.""And cannot land be rented?""How's one to rent it nowadays? The gentry, such as they were, have squandered all theirs. Men of business have got it all into their own hands. One can't rent it from them. They farmit themselves. We have a Frenchman ruling in our place; he bought the estate from our former landlord, and won't letit--and there's an end of it.""Who's that Frenchman?""Dufour is the Frenchman's name. Perhaps you've heard of him. He makes wigs for the actors in the big theatre; it is a good business, so he's prospering. He bought it from our lady, the whole of the estate, and now he has us in his power; he just rides on us as he pleases. The Lord be thanked, he is a good man himself; only his wife, a Russian, is such a brute that--God have mercy on us. She robs the people. It's awful. Well, here's the prison. Am I to drive you to the entrance? I'm afraid they'll not let us do it, though."到监狱路很远,时间已不早了,聂赫留朵夫就雇了一辆马车。

Properties of the States of Matter: Gases
• Low densities compared to solids and liquids. • Fluid.
The material exhibits a smooth, continuous flow as it moves.
Your taste and smell organs work because molecules in the thing you are sensing interact with the receptor molecule sites in your tongue and nose.
• In this chapter, we examine the physical interactions between molecules and the factors that effect and influence them.

Phase Changes: Melting
Tro's Introductory Chemistry, Chapter 12 12
Solids, Continued
• Some solids have their particles arranged in an orderly geometric pattern. We call these crystalline solids.
• Generally, we convert a material in the solid state into a liquid by heating it. • Adding heat energy increases the amount of kinetic energy of the molecules in the solid. • Eventually, they acquire enough energy to partially overcome the attractive forces holding them in place. • This allows the molecules enough extra freedom to move around a little and rotate.
• Take the shape of their container(s). • Expand to fill their container(s). • Can be compressed into a smaller volume.

The attractions are electrostatic. They depend on shape, polarity, etc.
• The ability of the molecules to overcome the attraction depends on the amount of kinetic energy they possess.

Gases
• In the gas state, the particles have complete freedom from each other. • The particles are constantly flying around, bumping into each other and their container(s). • In the gas state, there is a lot of empty space between the particles.
• Keep their own shape, do not take the shape of their container(s). • Keep their own volume, do not expand to fill their container(s). • Cannot be compressed into a smaller volume.
Salt and diamonds.
• Other solids have particles that do not show a regular geometric pattern over a long range. We call these amorphous solids.
Plastic and glass.
Tro's Introductory Chemistry, Chapter 12 2
The Physical States of Matter
• Matter can be classified as solid, liquid, or gas based on what properties it exhibits.
Tro's Introductory Chemistry, Chapter 12 11
Solids
• The particles in a solid are packed close together and are fixed in position.
Though they are vibrating.
On average.
Tro's Introductory Chemistry, Chapter 12 9
Gases, Continued
• Because there is a lot of empty space, the particles can be squeezed closer together. Therefore, gases are compressible. • Because the particles are not held in close contact and are moving freely, gases expand to fill and take the shape of their container(s), and will flow.
• Take the shape of their container(s). • Keep their volume, do not expand to fill their container(s). • Cannot be compressed into a smaller volume.

Interactions Between Molecules
• Many of the phenomena we observe are related to interactions between molecules that do not involve a chemical reaction.
Properties of the States of Matter: Solids
• High densities compared to gases. • Nonfluid.
They move as an entire ―block‖ rather than a smooth, continuous flow.
