2. A mass of 5 kg of saturated liquid-vapor mixture of water is contained in a piston- cylinder device at 100 kPa. Initially, 2 kg of the water is in the liquid phase and the rest is in the vapor phase. Heat is now transferred to the water, and the piston, which is resting on a set of stops, starts moving when the pressure inside reaches 200 kPa. Heat transfer continues until the total volume increases by 30 percent. Determine a) the initial and final temperatures, [10 marks] b) the mass of liquid water when the piston first starts moving, and [5 marks] c) the work done during this process. [5 marks] H20 m = 5 kg
