A gas undergoes a cycle in a piston–cylinder assembly consistingof the following three processes: Process 1–2: Constant pressure, p= 1.4 bar, V1 = 0.028 m3, W12 = 5 kJ Process 2–3: Compression withpV = constant, U3 = U2 Process 3–1: Constant volume, U1 - U3 = -25kJ There are no significant changes in kinetic or potential energy.(a) Calculate the net work for the cycle, in kJ. (b) Calculate theheat transfer for process 1–2, in kJ.
