A well-insulated rigid tank contains 6 kg of saturated liquid vapor mixture of water at 150 kpa. Initially, half of the mass is in liquid phase. An electric resistance heater placed in the tank is now turned on and kept on until all the liquid is vaporized. Determine.
(a) The electrical work.
(b) The entropy change of the steam during this process.
(c) The entropy generated in the system's universe.
