In an adiabatic process, the state of a gas is changed from ${P_1},{V_1},{T_1} $ to ${P_2},{V_2},{T_2}$. Which of the following relation is correct

  • A

    ${T_1}{V_1}^{\gamma - 1} = {T_2}{V_2}^{\gamma - 1}$

  • B

    ${P_1}{V_1}^{\gamma - 1} = {P_2}{V_2}^{\gamma - 1}$

  • C

    ${T_1}{P_1}^\gamma = {T_2}{P_2}^\gamma $

  • D

    ${T_1}{V_1}^\gamma = {T_2}{V_2}^\gamma $
