(《新华字典》“友”字注解的截图)
选择____________________ 植物的自语:__________________________, _____________________。 选择_________________________ 植物的自语:_____________________, _____________________。
一看上图,你就能发现“友”字有两个义项。①_如__何__得__知__这__一__点___?因 为它用“❶”“❷”作了分项标明。由第一个义项“朋友”引申出了“有 友好关系的”的意义,用“ ”标示,这样不仅②让___人__一__目__了__然__,还分出 了层次。义项之后往往③列__举___了__相__关__例__证__,比如“朋友”之后是“好~| 战~|网~”。这里,④_用___波__浪__号__(_或__缩__写__符___号__)_(_或__“__~__”__)__代__替__所__注__解__的__ _“__友__”__字___________,避免了“友”字的重复出现。因此,“友”字的注解 虽内容较多,但简洁明了。
中考化学真题 考点12 溶质质量分数 专题分类精选试题(含解析)
考点12 溶质质量分数一、选择题22.(苏州,第22题)如果配制6%的氯化钠溶液的溶质质量分数偏小,其原因是A .称取的氯化钠固体质量偏大B .转移称量好的氯化钠同体时,有少量洒落在桌面上C .量取水的体积偏小D .转移配制好的溶液时,有少量液体溅出【答案】B【解析】称取的氯化钠固体质量偏大、量取水的体积偏小,都会导致溶质质量分数偏大;转移称量好的氯化钠同体时,有少量洒落在桌面上,会导致溶质质量分数偏小;转移配制好的溶液时,有少量液体溅出,溶质质量分数不变。
21.(苏州,第21题)下列有关“配制50g 溶质质量分数为6%的氯化钠溶液”的操作错误的是A .使用托盘天平前,要先取下支撑托盘的垫圈,再调节天平平衡B .称取氯化钠前,要在天平两端的托盘上分别放质量相同的纸片C .移动游码使其右侧对齐3g 的刻度线,然后将氯化钠加到天平的右盘上D .取用规格为50mL 的量筒量取17mL 水,快到所需刻度时改用胶头滴管定容【答案】C【解析】称量药品质量时要将药品放在右盘,砝码放在左盘,故C 错误。
11. (江苏连云港,11题)右图是甲、乙、丙三种固体物质的溶解度曲线。
下列叙述错误..的是 A .t 1℃时,三种物质的溶解度大小顺序为:丙>乙>甲B .t 2℃时,甲、丙两种物质的溶液中溶质的质量分数相等C .若甲物质中混有少量的乙物质,可用降温结晶的方法提纯甲D .若要将组成在N 点的甲溶液转变为M 点的甲溶液,可以采用恒温蒸发溶剂的方法 【答案】B【解析】根据t1℃时的垂线可知,丙此时的溶解度最大、乙次之、甲最小,A 正确;t2℃时,要想比较甲、丙的溶质质量分数大小,还需指出溶液是饱和的,否则无法比较,B 错误;根据甲、乙的溶解度随温度变化的趋势可知,甲的溶解度受温度变化影响较大而乙受温度变化影响相对较小,因此可采用降温结晶的方法提纯甲,C 正确;比较N 点和M 点可知,M 点为t3℃时的饱和溶液,N 为该温度下的不饱和溶液,即D 选项要求在温度不变的条件下,将甲的不饱和溶液变饱和,可采用恒温蒸发溶剂或添加溶质的方法,D 正确。

2012年中考物理试题汇编精选精析--声现象2
2012年中考物理试题汇编精选精析--声现象21.(2012•安徽)成语“万籁俱寂”常用来形容夜晚的宁静,从声音的特性分析,这主要是指夜晚声音的很小.考点:响度。
专题:应用题。
分析:声音的响度是指声音的强弱.音调是指声音的高低.音色是指声音的品质与特色.声音的响度与声源振动的幅度有关,振动幅度越大,响度越大.解答:“万籁俱寂”说明声音的振幅较小,故发出声音的响度也会较小;故答案为:响度.点评:解决此类问题要会根据响度、音色和音调的定义区分乐音特征的三个因素.2.海洋动物质量越大,其叫声越是有力而低沉,即响度较大,音调较低.(甲)、(乙)两曲线为科考船声纳系统收录的500kg的海豚和100t的蓝鲸叫声的波形图,其中,甲(甲/乙)是蓝鲸发出的.图1考点:音调、响度与音色的区分。
专题:应用题。
分析:物理学中把人耳能感觉到的声音的强弱称为响度,把声音的高低称为音调;声音的响度与声源振动的幅度有关,振动幅度越大,响度越大;音调的高低与发声体振动快慢有关,物体振动越快,音调就越高.解答:由信息知:海洋动物质量越大,其叫声越是有力而低沉,故响度大,音调低;由图象知:甲的振幅大,频率低,故甲是质量大的蓝鲸的叫声的波形图,相反乙是海豚的叫声的波形图.故答案为:大;低;甲.点评:解决此类问题要结合声音特征中的音调和响度定义去分析解答.此外还要通过波形图来认识声音的特征,对波形图的各种特征要了解.3.(2012·常州)海洋动物质量越大,其叫声越是有力而低沉,即响度较大,音调较低.(甲)、(乙)两曲线为科考船声纳系统收录的500kg的海豚和100t的蓝鲸叫声的波形图,其中,甲(甲/乙)是蓝鲸发出的.图 2考点:音调、响度与音色的区分。
