본문내용
1. A piston-cylinder device contains 25g of saturated water vapor that is maintained at a constant pressure of 300 kPa. A resistance heater within the cylinder is turned on and passes a current of 0.2 A for 5min from a 120 V source. At the same time, a heat loss of 3.7 kJ occurs. (a) Show that for a closed system the boundary work Wb and the change in internal energy dU in the 1st law relation can be combined into one term, dH, for a constant-pressure process. (b) Determine the final temperature of the steam. (20 pt)
