A piston cylinder contains 25 g 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 .2A for 5 minutes from a 120 v source .At rhe same time ,a heat lass of 3.7KJ occurs
Show that,for a closed system the boundary work Wb and the change in internal energy dU in the first law relation can be combined into one term ,dH for a constant pressure process
(b) Determine the final temperature of the system
