Cp and Cv

[Nicole Nikolov 1K]

Is there a way to convert between the molar heat capacity at constant pressure and constant volume, Cp and Cv? Or would we have to be provided this information on an exam? Also, is there a way to convert between the specific heat capacity and the molar heat capacity?

[Michele 2C]

C_P,m = C_V,m + R

Or, the molar heat capacity at constant pressure is equal to the molar heat capacity at constant volume plus the gas constant.

Cp and Cv are usually just used for different conditions, either constant pressure or constant volume. I'm not sure when u would switch.

[IsabelLight2H]

If a system has Cp can it also have a Cv? and Vice Versa?

[Jason Ye 2I]

They are used for different conditions and questions

[BenJohnson1H]

If the gas constant, R, must be used, would it be given on the test?
