A gas contained inside a closed piston-cylinder device undergoes three processes. Process 1-2: Constant pressure Process 2-3: Constant volume Process 3-1: Compression during which PV1.3 = constant (polytropic process with n = 1.3) State 1 2 3 P, bar 10 3 V, m 0.1 0.5 U, KJ 125 625 80 (a) Draw a P-V diagram showing the three processes. Label states and identify process directions with arrows. (b) Find the work for the gas during each process, in kJ. (c) Calculate the heat transfer for the gas during each process, in kJ.
