(1) A constant-pressure insulated piston-cylinder device contains 1.7 kg of saturated liquid-vapor mixture of water at 150 kPa with an initial quality of 0.2. Energy is then added to the system by an electric heater until all the liquid is vaporized. The environment is at 99 kPa and 2°C. Calculate the change in energy of the contents in kJ.
