1.	An ideal gas with pressure P, volume V and temperature T is expanded isothermally to a volume 2V and a final pressure P_1 . The same gas is expanded adiabatically to a volume 2V, the final pressure is P_A. In terms of the ratio of the two specific heats for the gas gamma , the ratio P_I//P_Ais :
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
