摘要
通过热力学第二定律的推导可知,热力学中的熵判据适用条件是孤立系统。在封闭系统中若想使用熵判据,则不仅要计算系统的熵变,还要计算环境的熵变。而系统的熵变可以分为单纯物理变化、相变化和化学变化三种情况。
Through the deduction of the second law of thermodynamics, the entropy criterion of thermodynamics is applied to the isolated system, In the closed system, if you want to use the entropy criterion, It is not only to calculate the entropy change of the system, but also the entropy change of computing environment. The entropy change of the system can be divided into three kinds of simple physical change, phase change and chemical change.
