An insulated piston-cylinder device initially contains 10kg saturated liquid water at 200kPa. Now water steam at 0.5MPa and 350oC enters the cylinder from a supply line until all the water in the tank in the saturated vapor phase. During the charging process, pressure in the cylinder remains at 200kPa. Determine: (i) the final temperature in the cylinder; (ii) the mass of the steam that has entered.
