Application of Real Gas Which Obeys the Equation of State p(V-b)=RT in Thermodynamic Process

介绍p(Vm-b)=RT实际气体的热力学能、热容的特点,探讨了在等温过程、绝热可逆过程、焦耳实验和节流膨胀过程中一些热力学量的特点,通过该气体的化学势等温式推导了逸度系数及五个热力学函数的表达式。

In this work,the nature and characteristics of the thermodynamic energy and thermal capacity of real gas which obeys the equation of state p(Vm-b)=RT are introduced.The characteristics of thermodynamic parameters in isothermal process,adiabatic reversible process,Joule experiment,and throttling process are also discussed in detail.For a real gas,fugacity coefficient and the five of thermodynamic functions of the state are presented from chemical potential equation in isothermal process.
