温度、内能和热量是初中物理热学部分中涉及的三个非常重要的物理概念,很多同学常常理解不好,容易混淆,其实它们之间既有本质的区别又有紧密的联系,正确理解它们的区别和联系才是解题的关键. Temperature, internal energy and heat are three very important physical concepts involved in the physics section of junior high school physics. Many students are often poorly understood and easily confused. In fact, they are both fundamentally different and closely related, and their understanding is correct The difference and contact is the key to solving the problem.
