Comments

Also the decimal expansion of the molar specific heat of an ideal gas consisting of molecules with 5 degrees of freedom at constant volume.

The molar specific heat of an ideal gas consisting of molecules with n degrees of freedom at constant pressure and volume can be calculated respectively with the following formulae:

- Cv(n) = n/2 R;

- Cp(n) = (1 + n/2) R;

Where R = Cp(n) - Cv(n) = A070064 is the molar gas constant.

Molecules of a monatomic gas have 3 degrees of freedom. Diatomic and polyatomic molecules can have additional degrees of freedom.

Formula

Cp(1) = (1 + 3/2) * R = 5/2 * A070064.

Cp(1) = Cv(1) + R = A272001 + A070064.

Example

Cp(1) = 20.7861565453831 J mol^-1 K^-1.
