The Generalized Van-der-Waals-Bertlo Equation. Part III. Description of the Dependence of the Dielectric Permeability of Gas on Temperature and Pressure

In the present paper we consider application of equation of state for model gases to the description of experimental dependencies of dielectric permeability on pressure and temperature for nonpolar gases. The case of argon is regarded as an example. It is demonstrated that the generalized Van-der-Waals-Berthelot equation describes the dependence of dielectric permeability on pressure and temperature with good accuracy. It is shown that the measurement of dielectric permeability using the isotherms with small temperature increments provides a means to obtain the exact tabulated equation of state. This result can be used in other areas of investigation.
