A mass of 4 kg of saturated liquid-vapor mixture of water is in a piston-cylinder at 175 kPa. Initially, 3kg of the mixture is in liquid form and the rest is vapor. The device is heated until the piston, resting on stops (see image below), starts to move as the pressure reaches 600 kPa. Heat transfer continues until the volume is doubled from the initial state. What is the final temperature in centigrade? How much of the water is in a liquid state when the piston moves (give me a mass in kg)? What is the boundary work accomplished in kilojoules to three significant digits.
