Problem 1 A gas within a piston-cylinder assembly undergoes a thermodynamics cycle

Problem 1 A gas within a piston-cylinder assembly undergoes a thermodynamics cycle consisting of three processes: Process 1-2 Expansion with Pv=cte. From P1-3 bar V1=0.02m to V2=0.08m U2-U1=0. Process 2-3 constant volume to pressure 3bar. Process 3-1 Constant pressure compression to volume V1 U1-U3=-45kJ. There are no significant changes in kinetic and potential energy. Determine the heat transfer and work for each process, is this a power cycle or a refrigeration cycle?
