Vedclass · Answer

(A) According to Mayer's relation,for an ideal gas,the difference between the molar heat capacity at constant pressure $(C_P)$ and the molar heat capacity at constant volume $(C_V)$ is equal to the universal gas constant $(R)$.When $C_P$ and $C_V$ are expressed in calories per mole per Kelvin $(cal \cdot mol^{-1} \cdot K^{-1})$ and $R$ is in Joules per mole per Kelvin $(J \cdot mol^{-1} \cdot K^{-1})$,we must divide $R$ by the mechanical equivalent of heat $(J)$ to maintain unit consistency.Therefore,the relation is $C_P - C_V = \frac{R}{J}$.
