Carbon monoxide gas (CO) contained within a piston cylinder assembly undergoes three processes in series.
Process 1-2: Expansion from P1= 5 bar, V1=0.2m3, to V2=1 m3, during which the pressure volume relationship in pV= Constant.
Process 2-3: Constant volume heating from state 2 to state 3, where P3= 5 bar.
Process 3-1: Constant-pressure compression to the initial state
Sketch the processes in series on p-V coordinates and evaluate the work for each process in kJ.
