Figure shows graphs of pressure vs density for an ideal gas at two temperature T_(1) and T_(2) . Which of the following is correct ?

A cylinder of cross-section area. A has two pistons of negligible mass separated by distances l loaded with spring of negligible mass. An ideal gas at temperature T_(1) is in the cylinder where the springs are relaxed. When the gas is heated by some means its temperature becomes T_(2) and the springs get compressed by (l)/(2) each . if P_(0) is atmospheric pressure and spring constant k= (2P_(0)A)/(l) , then find the ratio of T_(2) and T_(1) .

An insulated container of gas has two chambers separated by an insulating partition. One of the chambers has volume V_1 and contains ideal gas at pressure P_1 and temperature T_1 .The other chamber has volume V_2 and contains ideal gas at pressure P_2 and temperature T_2 . If the partition is removed without doing any work on the gas, the final equilibrium temperature of the gas in the container will be
