3. A gas contained within a closed piston-cylinder assembly undergoes three processes in series: Process 1-2: Constant volume from P₁ = 1 bar, V₁ = 4 m³ to state 2, where P₂ = 2 bar; Process 2-3: Compression to V3 = 2 m³, during which the pressure-volume relationship is PV = constant; Process 3-4: Constant pressure to state 4, where V4 = 1 m³; (a) Sketch the processes in series on P-V coordinates. (b) Evaluate the magnitude of work in kJ for EACH process. To make the unit consistent, you might need to convert the unit of pressure from bar to Pa.
