A gas within a piston-cylinder assembly undergoes a thermodynamic cycle consisting of three processes:
Process 1-2: Compression with pV 5 constant, from p1 5 1 bar, V1 5 2 m3 to V2 5 0.2 m3, U2 2 U1 5 100 kJ.
Process 2-3: Constant volume to p3 5 p1.
Process 3-1: Constant-pressure and adiabatic process.
There are no significant changes in kinetic or potential energy. Determine the net work of the cycle, in kJ, and the heat transfer for process 2-3, in kJ. Is this a power cycle or a refrigeration cycle? Explain.
