Q6. A piston-cylinder device initially contains 0.3 m of 0.8-kg saturated liquid water and steam mixture at 100 kPa. An electric heater within the device is turned on and is allowed to pass a current of 2.5 A from a 120-V source. There's no other form of energy transfer besides the electrical work and boundary work. The piston initially rests on a set of stops, and a pressure of 200 kPa is required to move the piston. Afterwards, the system continues to raise the piston and eventually reaches a temperature of 400C. For this problem you must use the property tables from the textbook. Determine the total time it takes (in hours) for the system to reach the final state. Please pay attention: the numbers may change since they are randomized. Your answer must include 3 places after the decimal point. LAW
