摘要

液态水作为真实气体的表示被用来修正范德华状态方程，以描述液态水在广泛的压力和温度范围内的等温线、等线和等压线。新的热方程允许标准过渡到热力学，同时再现内能U，自由能F，热容CV和熵S。

Modifying the van der Waals Equation to Describe the Thermodynamic Properties of Liquid Water

A representation of liquid water as a real gas is used to modify the van der Waals equation of state for describing isotherms, isochores, and isobars of liquid water in wide ranges of pressure and temperature. The new thermal equation allows the standard transition to thermodynamics while reproducing internal energy U, free energy F, heat capacity C_V, and entropy S.
