An insulated piston-cylinder device contains 2Kg of saturated liquid water with an electric resistance heater in the water inside the cylinder. The water remains at a constant pressure of 120KPa as electrical work of 1500KJ enters the water. the surroundings are at 25 degrees C and 100KPa.
Determine
a) The minimum work with which this process can be accomplished
b) Total exergy destroyed during this process.
