Background: It is interesting to check whether an equation of the mechanocaloric effect in condensed phases can be applied for the description of adiabatic compression and expansion of gases. It is also useful to derive the equation for adiabatic compression and expansion of gases using the value of adiabatic heat capacity earlier obtained by the author.

Methods: Clément-Desormes method, Theory.

Significant Findings: A new equation for the description of adiabatic processes is derived which gives a good description for real gases. The accuracy of this equation is the same one as that of the traditional one. It is shown that an equation of the mechanocaloric effect also can be used for the description of adiabatic compression and expansion of gases.
