In the case of modelling of nonstationary flows of heat-conductive gas in three-temperature approximation the system of differential equations is completed by state equations for medium components. It is convenient to set them in the form of functions on density and temperature. The condition of thermodynamic equilibrium imposes restrictions on these functions. The construction of state equations for partially ionized plasma is considered. Plasma is simulated by definition of function of ion charge in the form of exponential function on density and temperature.
