WebSummary. For an ideal gas, the molar capacity at constant pressure Cp C p is given by Cp = CV +R = dR/2+ R C p = C V + R = d R / 2 + R, where d is the number of degrees of freedom of each molecule/entity in the system. A real gas has a specific heat close to but a little bit higher than that of the corresponding ideal gas with Cp ≃CV +R.
