A rigid tank A of volume 0.6 m^3 contains 3 kg water at 120 degrees Celsius and the rigid tank B is 0.4 m^3 with water at 600 kpa, 200 degrees Celsius. They are connected to a piston cylinder initially empty with closed valves. the pressure in the cylinder should be 800 kpa to floatthe piston. now the valves are slowly opened and heat is transferred so the water reaches a uniform state at 250 degrees Celsius with the valves open. find the final volume and pressure and the work and heat transfer in the process.
