Carbon monoxide gas (CO) contained within a piston– cylinder
assembly undergoes three processes in series:
Process 1–2: Expansion from p1 = 4.5 bar, V1
= 0.8 m3 to V2 = 1.4 m3, during
which the pressure-volume relationship is pV = constant.
Process 2–3: Constant-volume heating from state 2 to state 3, where
p3 = 4.5 bar.
Process 3–1: Constant-pressure compression to the initial
state.
