A gas undergoes a cycle in a piston-cylinder assembly consisting of the following three processes: Process 1-2: Constant pressure, p = 1.4 bar, V₁ = 0.028 m³, W12 = 10 kJ Process 2-3: Compression with pV = constant, U3 = U₂ Process 3-1: Constant volume, U₁ - U3 = -25 kJ There are no significant changes in kinetic or potential energy. (a) Calculate the net work for the cycle, in kJ. (b) Calculate the heat transfer for process 1-2, in kJ. Part A Your answer is correct. Calculate the net work for the cycle, in kJ. Wcycle = -7.63 kJ
