Just trying to locate specific heat constants with constant volume (not pressure), any ideas where to find this?

If you have a thermodynamic set of property tables it would be in the column with Cv (v should be a subscript) if you are looking at Cp that is the specific heat at constant pressure. They should be fairly close in most nonextreme conditions so becareful what your looking at

[latex]C_p[/latex] : Specific Heat at constant pressure
[latex]C_v[/latex] : Specific Heat at constant volume Also [latex]C_p  C_v = R[/latex] [latex]\frac {C_p}{C_v} = lamda[/latex] where lamda = [latex]1 + \frac {2}{f}[/latex] Where f=degrees of freedon for monoatomic gas , f=3 for diatomic gas , f=3 You can solve for two expressions at the top to get Cp BJ

Constant Volume Specific Heat
One correction to Dr.Brain's post. f for diatomic gases is 5
