One kilogram of ammonia initially at 8.0 bar and 50°c undergoes a process to 4.5 bar, 20°c while being rapidly expanded in a piston–cylinder assembly. heat transfer between the ammonia and its surroundings occurs at an average temperature of 40°c. the work done by the ammonia is 40 kj. kinetic and potential energy effects can be ignored. determine the heat transfer, in kj, and the entropy production, in kj/k.
