A certain mass of an ideal gas at pressure `P_1` is adiabatically expanded from an initial volume `V_1` to a final volume `V_2`. The resulting pressure `P_2` of the gas is given by:

A

`P_2=P_1(V_1/V_2)^gamma`

B

`P_2=P_1(V_1/V_2)^(1//gamma)`

C

`P_2=P_1(V_1/V_2)^((gamma-1)/gamma`

D

`P_2=P_1(V_1/V_2)^(gamma/(gamma-1))`
