The molar specific heats of an ideal gas at constant pressure and volume are denoted by $C _{ P }$ and $C _{ V }$ respectively. If $\gamma=\frac{C_{p}}{C_{V}}$ and $R$ is the universal gas constant, then $C _{ V }$ is equal to
  • A$\frac{R}{{\gamma - 1}}$
  • B$\;\frac{{\gamma - 1}}{R}$
  • C$\;\gamma R$
  • D$\;\frac{{\gamma + 1}}{{\gamma - 1}}$
