8.7.3 Defining Specific Heat Capacity Using Kinetic Theory

If you are using the gas law (as described in Section  8.3), you have the option to define the specific heat capacity using kinetic theory as

where $f_i$ is the number of modes of energy storage (degrees of freedom) for the gas species $i$ which you can input by selecting kinetic-theory from the drop-down list to the right of Cp in the Create/Edit Materials dialog box. The solver will use your kinetic theory inputs in Equation  8.7-5 to compute the specific heat capacity. See Section  8.13 for details about kinetic theory inputs.
