1) 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, V, = 0.028 m³, W,2 = 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.
