A mass of 5 kg of saturated liquid-vapor mixture of water is contained in a piston-cylinder device at 125 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 300 kPa . Heat transfer continues until the total volume increases by 20 percent.

Determine (a) the initial and final temperatures, (b) the mass of liquid water when the piston first start moving, and (c) the work done during this process. Also show the process on a P-v diagram.
