A rigid tank has a volume of 0.01 m³ . It initially contains saturated water at a temperature of 200^oC and a quality of 0.4. The top of the tank contains a pressure regulating valve which maintains the vapor at constant pressure. This system undergoes a process where it is heated until all the liquid vaporizes. How much heat in (kJ) is required? You may assume there is no pressure drop in the exit line.
