A gas contained within a piston-cylinder assembly undergoes three processes in serial:
Process1-2: Compression with PV = constant from p1= 1 bar V1 = 1.0 m3 to V2 = 0.2m3.
Process 2-3: Constant-pressure expansion to V3 = 1.0 m3.
Process 3-1: Constant Volume
Sketch the processes in series on a p-V diagram labeled with pressure and volume values at each numbered state.
