温度、内能和热量是初中热学涉及的三个基本物理量.它们都与物体内大量分子无规则运动的剧烈程度有关,但各自的含义是不同的, 学习过程中最好用“对比”的方法搞清它们之间的区别与联系. Temperature, internal energy, and heat are the three basic physical quantities involved in junior high school thermal science. They are all related to the intensity of the irregular movement of a large number of molecules in an object, but their respective meanings are different. The “contrast” method is best used in the learning process. Find out the differences and connections between them.
