A gas contained in a piston-cylinder assembly undergoes two processes, A and B, between the same end states, 1 and 2, where p = 1 bar, V = 1 m, U = 400 kJ and p2 = 2 bar, V = 0.500 m, U = 480 kJ: Process A: Constant-volume process from state 1 to a pressure of 2 bar, followed by a constant-pressure process to state 2. Process B: Process from 1 to 2 during which the pressure volume relation is pV = constant. Kinetic and potential effects can be ignored. For each of the processes A and B, (a) evaluate the work, in kJ, and (b) evaluate the heat transfer, in kJ. Part A For Process A, evaluate the work and the heat transfer, both in kJ. WA QA = 0 KJ kJ
