One Kg of ammonia is contained in a well-insulated piston-cylinder assembly fitted with an electrical resistor of negligible mass. The ammonia is initially at 150 kPa and 80% quality. The resistor is activated until the volume of ammonia increases by 25% while pressure change is negligible. Ignoring effects of motion and gravity and with an ambient state at T0 = 15 oC and PO = 1 atm, determine: a. Energy transfer from the electrical resistor and the accompanying exergy transfer b. Energy transfer by work to the piston and the accompanying exergy transfer c. Exergy change of the ammonia d. Exergy destruction: i. From exergy balance ii. From entropy balance
