Mechanical Engineering

A mass of 3 kg of saturated liquid-vapor mixture of water iscontained in a piston-cylinder device at 175 kPa. Initially, 2 kgof the water is in the liquid phase and the rest is in the vaporphase. An electrical heater is in operation, and the piston risesuntil it hits a set of stops, which are set at double the initialvolume. Electrical heating continues until the pressure reaches 500kPa. Determine (a) the initial and final temperatures, (b) the massof liquid water when the piston first hits the stops, and (c) theelectrical work done during this process. Show all equations.
