An insulated rigid tank contains 5 kg of helium gas at 440 kPa and 31C. A valve is now opened, and helium is allowed to escape until the pressure inside drops to 200 kPa. Assuming the helium remaining inside the tank has undergone a reversible, adiabatic process; determine the final mass of the tank.
