3 moles of water vapor at 110 °C was heated to 140 °C in a constant volume container, and the pressure of water vapor in the final conditions was calculated to be 1 atm. Then, the container was changed to a constant pressure container (external pressure = 1 atm) and the volume of the gas was increased 3-fold under these conditions without any heat exchange. What is the change in the internal energy of the system. (For water vapor c = 2.01 J g-' K-").
