Vedclass · Answer

(D) According to Mayer's relation for molar specific heats,$C_{p,m} - C_{v,m} = R$. Since $C_p$ and $C_v$ are specific heats per unit mass,we have $C_p = \frac{C_{p,m}}{M}$ and $C_v = \frac{C_{v,m}}{M}$,where $M$ is the molar mass of nitrogen $(N_2)$. The molar mass of $N_2$ is $M = 28 	ext{ g/mol}$. Therefore,$C_p - C_v = \frac{C_{p,m} - C_{v,m}}{M} = \frac{R}{M}$. Substituting $M = 28$,we get $C_p - C_v = \frac{R}{28}$.

If $C_p$ and $C_v$ denote the specific heats of nitrogen per unit mass at constant pressure and constant volume respectively,then
