A thermally insulated chamber of volume $2V_0$ is divided by a frictionless and insulated piston of cross-sectional area S into two equal parts A and B. Part A has an ideal diatomic gas at pressure ${\mathrm{P}}_0$ and temperature ${\mathrm{T}}_0$ and in part B is vacuum. A massless spring of force constant K is connected with the piston and wall as shown. Initially the spring is unstretched. The gas in A expands slowly with help of an external agent. After equilibrium, the agent is removed. Let the spring compression be ${\mathrm{x}}_0$. then
