If `C_(p) and C_(v)` denoted the specific heats of unit mass of nitrogen at constant pressure and volume respectively, then

C_(p) and C_(v) denote the molar specific heat capacities of a gas at constant pressure and volume respectively. Then :

C_(p) and C_(v) denote the molar specific heat capacities of a gas at constant pressure and volume respectively. Then :

If C_(P) and C_(V) denote the specific heats of nitrogen per unit mass at constant pressure and constant volume respectively then

If C_P and C_V denote the specific heats of nitrogen per unit mass at constant pressure and constant volume respectively, then
