In this paper, by use of the second virial coefficient (12-6) in the Lennard–Jones potential, an analytical procedure to evaluate the specific heat capacity and speed of sound of gases is presented. The obtained formulas yield accurate and fast evaluation of both quantities. By using obtained analytical expressions, the heat capacity and speed of sound of the gases Ar, He, Xe, , , , , , , , , and air were calculated in the temperature range from 100 to 2000 K and over the pressure range from 0.1 atm to approximately 15 atm. The computational results are in good agreement with the data available in the literature.
