A piston-cylinder device contains 25 g of saturated water vapor that is kept at maintained at a constant P of 300 kPa. A resistance heater within the cylinder is turned on and passes a current of 0.2 A for 5 min from a 120-V source. At the same time, a heat loss of 3.7 kJ occurs. Determine the final T of the steam.
