比热容是反映物质吸热能力强弱的物理量,同时也是反映物质温度改变难易程度的物理量.该知识点是初中物理的一个难点,其概念比较抽象,又因为与质量、温度的变化量、吸收或者放出的热量等多个物理量有关.不同物质的比热容一般不同,即使是同一种物质,在不同状态下的比热容也是不同的,所以比热容是物质的一个基本属性.下面我们通过一些典型例题的讲解来更好地认识比热容.
The specific heat capacity is a physical quantity that reflects the ability of material to absorb heat and is also a physical quantity that reflects the difficulty of material temperature change.This knowledge point is a difficult point of junior high school physics and its concept is rather abstract and because of the change with quality and temperature, Or the release of heat and other physical quantities related to different materials, the specific heat capacity are generally different, even if the same material, in different states of the specific heat capacity is different, so the specific heat capacity is a material property of the following we pass some typical examples to explain To better understand the specific heat capacity.
