WebHere, we focus on the heat capacity with the volume held constant. We can calculate it for an ideal gas. Heat Capacity of an Ideal Monatomic Gas at Constant Volume. We define the molar heat capacity at constant volume [latex]C_V[/latex] as [latex]C_V = \frac{1}{n}\frac{Q}{\Delta T},\text{with V held constant.}[/latex] This is often expressed in ... 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.
