A gas contained within a piston-cylinder assembly undergoes three processes in series:
Process 1-2: Constant volume from Pa = 1 bar, V? = 4 m3 to state 2, where p2-2 bar.
Process 2-3: Compression to V 2 m3, during which the pressure-volume relationship is pV-constant.
Process 3-4: Constant pressure to state 4, where V -m3.
Sketch the processes in series on p-Vcoordinates and evaluate the work for each process, in kJ.
