A closed, rigid tank is filled with water. Initially, the tank holds 9.9 ft3 of saturated vapor and 0.1 ft3 of saturated liquid, each at 212°F. The water is heated until the tank contains only saturated vapor. For the water, determine (a) the quality at the initial state, (b) the temperature at the final state, in °F, and (c) the heat transfer, in Btu. Kinetic and potential energy effects can be ignored.
