Problem: A well-insulated rigid tank contains 2 kg of a saturated mixture of liquid and vapor at 150 kPa. Initially, three quarters of the water is in the liquid phase. a resistor • lying in the tank is connected to a 110 V source and a current of 8 A flows through the resistor when the switch is pressed, Determine how long it will take for all the water in the tank to vaporize, and sketch the process on a T-v diagram.
