初中物理知识点总结
第一章声现象知识归纳
1 . 声音的发生：由物体的振动而产生。振动停止，发声也停止。
2．声音的传播：声音靠介质传播。真空不能传声。通常我们听到的声音是靠空气传来的。
3．声速：在空气中传播速度是：340米/秒。声音在固体传播比液体快，而在液体传播又比空气体快。
4．利用回声可测距离：S=1/2vt
5．乐音的三个特征：音调、响度、音色。(1)音调:是指声音的高低，它与发声体的频率有关系。
(2)响度:是指声音的大小，跟发声体的振幅、声源与听者的距离有关系。
6．减弱噪声的途径：(1)在声源处减弱；(2)在传播过程中减弱；(3)在人耳处减弱。
7．可听声：频率在20Hz～20000Hz之间的声波：超声波：频率高于20000Hz的声波；次声波：频率低于20Hz的声波。
8．超声波特点：方向性好、穿透能力强、声能较集中。具体应用有：声呐、B超、超声波速度测定器、超声波清洗器、超声波焊接器等。
9．次声波的特点：可以传播很远，很容易绕过障碍物，而且无孔不入。一定强度的次声波对人体会造成危害，甚至毁坏机械建筑等。它主要产生于自然界中的火山爆发、海啸地震等，另外人类制造的火箭发射、飞机飞行、火车汽车的奔驰、核爆炸等也能产生次声波。
第二章物态变化知识归纳
1. 温度：是指物体的冷热程度。测量的工具是温度计, 温度计是根据液体的热胀冷缩的原理制成的。
2. 摄氏温度(℃):单位是摄氏度。1摄氏度的规定：把冰水混合物温度规定为0度，把一标准大气压下沸水的温度规定为100度，在0度和100度之间分成100等分，每一等分为1℃。
３．常见的温度计有(1)实验室用温度计；(2)体温计；(3)寒暑表。
体温计：测量范围是35℃至42℃，每一小格是0.1℃。
4.
