The relation between C_p and C_v is known as Mayer’s relation.

The relation is given by,

C_{p} - C_{v} = R

Where C_pC_vand R are measured in same units.

C_Pis the specific heat at constant pressure, and
C_Vis the specific heat at constant volume.

What is the value of molar specific heat of an ideal gas at constant volume in terms of the degree of freedom of a gas molecule?

Molar specific heat of an ideal gas at constant volume in terms of the degree of freedom of a gas molecule is given by,

\frac{f}{2} R

where, f is the degree of freedom.
