初三物理下册基础知识归纳测试题附答案
这篇关于初三物理下册基础知识归纳测试题附答案，是特地为大家整理的，希望对大家有所帮助！一、宇宙和微观世界
宇宙→银河系→太阳系→地球
物质由组成;分子是保持物质原来的一种粒子;一般大小只有百亿分之几米(0.3-0.4nm)。
物质三态的性质：
固体：分子排列紧密，粒子间有强大的。固体有一定的形状和体积。
液体：分子没有固定的位置，运动比较自由，粒子间的作用力比固体的小;液体没有确定的形状，具有性。
气体：分子极度散乱，间距很大，并以高速向四面八方运动，粒子间作用力微弱，易被压缩，气体具有流动性。
分子由原子组成，原子由和(核外)电子组成(和太阳系相似)，原子核由质子和组成。
纳米科技：(1nm=10m)，纳米尺度:(0.1-100nm)。研究的对象是一小堆分子或单个的原子、分子。
二、质量
质量：物体的多少。质量是物体本身的一种属性，它的大小与、状态、位置、温度等无关。物理量符号：m。
单位：kg、t、g、mg。
1t=kg,1kg=g,1g=mg.
天平：
1、原理：原理。
2、注意事项：被测物体不要超过天平的称量;向盘中加减砝码要用镊子，不能把砝码弄脏、弄湿;潮湿的物体和化学不能直接放到天平的盘中
3、使用：(1)把天平放在水平台上;(2)把游码放到标尺放到左端的处，调节横梁上的平衡螺母，使天平平衡(指针指向分度盘的中线或左右摆动幅度相等)。(3)把物体放到盘，盘放砝码，增减砝码并调节游码，使天平平衡。(4)读数：砝码的总质量加上游码对应的刻度值。
注：失重时(如：宇航船)不能用天平称量质量。
三、密度
密度是物质的一种特殊属性;同种物质的质量跟体积成正比，质量跟体积的比值是定值。
密度：叫做这种物质的密度。
密度大小与物质的种类、状态有关，受到温度的影响，与质量、体积无关。
公式：
单位：kg/m3，g/cm3kg/m3=1g/cm3。
1L=1dm3=m3;1ml=1cm3=L=m3。
四、测量物质的密度
实验原理：
实验器材：、、烧杯、细线
量筒：测量液体体积(可间接测量固体体积)，读数是以凹液面的最低处为准。
测固体(密度比水大)的密度：步骤：
1、用天平称出固体的质量m;2、在量筒里倒入适量(能浸没物体，又不超过刻度)的水，读出水的体积V1;3、用细线拴好物体，放入量筒中，读出总体积V2。
注：若固体的密度比水小，可采用针压法和重物下坠法。
测量液体的密度：步骤：1、用天平称出烧杯和液体的总质量m1;2、把烧杯里的液体倒入量筒中一部分，读出液体的体积V2;3、用天平称出剩余的液体和烧杯的质量m2。
五、密度与社会生活
密度是物质的基本属性(特性)，每种物质都有自己的密度。
密度与温度：温度能够改变物质的密度;气体热膨胀最显著，它的密度受温度影响;固体和液体受温度影响比较小。
水的反常膨胀：4℃密度;水结冰体积变大。
密度应用：1、(测密度)2、求质量3、求体积。
