2.41 A gas contained within a piston-cylinder assembly undergoes two processes, A and B, between the same end states, 1 and 2 , where p1=10bar,V1=0.1m3,U1=400kJ and p2=1bar,V2=1.0m3,U2=200kJ : Process A: Process from 1 to 2 during which the pressurevolume relation is pV= constant. Process B: Constant-volume process from state 1 to a pressure of 2bar, followed by a linear pressure-volume process to state 2. Kinetic and potential energy effects can be ignored. For each of the processes A and B, (a) sketch the process on pV coordinates, (b) evaluate the work, in kJ, and (c) evaluate the heat transfer, in kJ
