Appendix C Virial Coefficients for Quantum Gases

T his appendix presents the relationship between virial coefficients B and C with B′ and C′. In addition, it presents second and third virial coefficient data for quantum gases (hydrogen, helium, and neon) as a function of temperature.

Virial Equation as a Power Series in Density or Pressure

The compressibility factor of a gas can be expressed by an expansion using either the density or the pressure as the independent variable:

where, for a pure gas, virial coefficients B, C, D ...
