An insulated rigid tank contains 5 kg of a saturated liquid-vapor mixture of water at a. 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. (a) determine how much time it will take to vaporize all the water in the tank, and (b) show the process on a t-v diagram with respect to the saturation lines.
