1.	A certain mass of an ideal gas having volume V_1 and pressure P_1 at absolute temperature T_1. When it undergoes adiabatic change , its pressure is increasedto P_2 and volume is increased to V_2 and temperature is increased to T_2. If gamma is the ratio of two specific heat capacities of the gas gamma=C_P/C_V then select the incorrect equation from the following.
Answer» `T_2=T_1(V_1/V_2)^(GAMMA-1)` `P_2=P_1(V_1/V_2)^(gamma-1)` `P_1V_1 = P_2V_2` `T_2=T_1(P_1/P_2)^((gamma-1)/(gamma))` ANSWER :C
