中学物理课本中,热力学第一定律和热力学第二定律已经有了比较详细的介绍,但是对热力学第三定律的说明比较简单,只有这么一个表述:热力学零度不可达到.在教学的过程中,不少教师及学生都提出了同样的问题:为什么绝对零度不能达到呢?同时在对热力学第三定律的理解方面,也出现了许 In the middle school physics textbooks, the first law of thermodynamics and the second law of thermodynamics have been introduced in more detail, but the description of the third law of thermodynamics is relatively simple, and there is only one such expression: thermodynamic zero is unachievable. In the process of teaching, not Less teachers and students have asked the same question: Why can’t absolute zero be achieved? At the same time, there are also promises in the understanding of the third law of thermodynamics.
