2. A gas undergoes a cycle in a pistoncylinder assembly consisting of the following three processes: Process 1→2: Constant pressure, p = 1.4 bar, V₁ = 0.028 m³, W12 = 10.5 kJ Process 2→3: Compression with pV = constant, U3 = U₂ Process 3→1: Constant volume, U₁ - U3 = -26.4 kJ There are no significant changes in kinetic or potential energy. a. Sketch the cycle on a p-V diagram. b. Calculate the net work for the cycle, in kJ. c. Calculate the heat transfer for process 1-2, in kJ.
