WebA molecule with n degrees of freedom has n 2 different ways of storing energy. Each degree of freedom is associated with `1/2`RT average energy per mole. A monoatomic gas molecule has 1 rotational degree of freedom whereas the diatomic molecule has 2 rotational degrees of freedom. CH 4 has a total of 6 degrees of freedom. WebApr 9, 2024 · There are three degrees of freedom in the case of the monoatomic gas. Thus, the average kinetic energy per degree of freedom is represented as- KEx= 1 2 KbT A molecule possesses three translational degrees of freedom, which is free to move in space and hence needs three coordinates in order to specify its location.

By the equipartition theorem, internal energy per mole of gas equals cv T, where T is absolute temperature and the specific heat at constant volume is cv = (f)(R/2).
