The molar specific heats of an ideal gas at constant pressure and volume are denoted by $\displaystyle \mathrm{C}_{\mathrm{p}}$ and $\displaystyle \mathrm{C}_{\mathrm{v}}$, respectively. If $\displaystyle \gamma=\frac{\mathrm{C}_{\mathrm{p}}}{\mathrm{C}_{\mathrm{v}}}$ and R is the universal gas constant, then $\displaystyle \mathrm{C}_{\mathrm{v}}$ is equal to :
Official answer
(2)
$\displaystyle \frac{\mathrm{R}}{(\gamma-1)}$
