对范德瓦耳斯气体的热力学函数及热容量的研究

A Reaserch For Van der Waals' Gases Thermodynamic Functions and Their Heat Capacity

由热力学函数的定义，并结合范德瓦耳斯方程，推导出范德瓦耳斯气体的几个基本热力学函数，分析了其特性，并研究了范德瓦耳斯气体的定容摩尔热容量和定压摩尔热容量的一些性质，指出了其同理想气体的区别。

In this paper from the definition of thermodynamic funtions as well as Van der waals' equation,several basic thermodynamic funtions for Van der waals' gases are deduced,their characters analyzed,and a further reaserch for the charaters of C P and C V in Van der waals' gases is made,then the differences between Van der waals' gases and the ideal gases are pointed out.
