Abstract:

In this work, the nature and characteristics of the thermodynamic energy and thermal capacity of real gas which obeys the equation of state p(V_m − 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.

Key words: Real gas, Thermodynamic parameter, Thermal capacity, Isothermal process, Throttling expansion, Chemical potential
