A gas of 2 kg in a closed system undergoes three processes in series:
Process 1-2: isochoric process from state 1 with p, = 1 bar, V, = 4 m³ to state 2, where p2 = 2 bar.
Process 2-3: compression state 3 where V3 = 2 m³, during which the pressure-volume relation is
ру 3 const.
Process 3-4: Isobaric process to state 4, where V. = 1 m³.
