A piston-cylinder device initially contains 20 g of saturated water vapor at 300 kPa. A resistance heater is operated within the cylinder with a current of 0.4 A from a 240 V source until the volume doubles. At the same time a heat loss of 4 kJ occurs. Determine (a) the final temperature (b) duration of the process (c) draw the t-v diagram for this process indicating the SATURATION CURVE, RELEVANT PRESSURE LINE(S), PROCESS PATH and LOCATIONS FOR SYSTEM STATES of interest
