A thermally insulated vessel is partitioned into two compartments by a rigid, movable, and frictionless diathermal (heat conducting) piston. Each compartment contains one mole of an ideal gas. The piston is initially clamped and the temperature, pressure, and volume of the gases in the first and second compartments are: T₁=400 ~K , V₁=2 L ; and T₂=200 ~K , V₂=4 ~L . The piston is then released and the system is allow
