Well-insulated rigid tank contains 2 kg of a saturated liquid-vapor mixture of water at 150 kpa. initially, three-quarters of the mass is in the liquid phase. an electric resistor placed in the tank is connected to a 110 v source, and a current of 8 a flows through the resistor when the switch is turned on. determine how long it will take to vaporize all the liquid in the tank. also, show the process on a t-v diagram with respect to the saturation curve.
