A thermally insulated chamber of volume 2v0 is divided by a frictionless piston of area ‘S’ into two equal parts A and B. Part ‘A’ has an ideal gas at pressure P0 and temperature T0 and in part B there is vacuum. A massless spring of force constant k is connected with piston and the wall of the container as shown. Initially spring is unstretched. Gas in chamber A is allowed to expand. Consider the compression in spring to be x0 in equilibrium.
