One mole of an ideal gas $(C_p/C_v = \gamma)$ at absolute temperature $T_1$ is adiabatically compressed from an initial pressure $P_1$ to a final pressure $P_2$. The resulting temperature $T_2$ of the gas is given by

  • A
    $T_2 = T_1 \left( \frac{P_2}{P_1} \right)^{\frac{\gamma}{\gamma - 1}}$
  • B
    $T_2 = T_1 \left( \frac{P_2}{P_1} \right)^{\frac{\gamma - 1}{\gamma}}$
  • C
    $T_2 = T_1 \left( \frac{P_2}{P_1} \right)^{\gamma}$
  • D
    $T_2 = T_1 \left( \frac{P_2}{P_1} \right)^{\gamma - 1}$
