A piston-cylinder assembly undergoes a cycle consisting of the following three processes: Process 1-2: Compression with constant internal energy Process 2-3: Constant-volume cooling to p3 100 kPa, V3 = 0.1 m³ Process 3-1: Constant-pressure expansion with W31 = 12 kJ = Sketch the cycle on a p-V diagram, labeling each of the states and indicating the process directions w arrows. If the work for the entire cycle is Wcycle = -20 kJ and changes in kinetic and potential ener are negligible, determine: a) The volume at state 1 [0.2 m³] b) The work and heat transfer for process 1-2 [-32 kJ, – 32 kJ] c) Is this cycle a power cycle or a refrigeration cycle? Explain.
