Thanks! :)

2.48 A gas undergoes a thermodynamic cycle consisting of three processes: Process 1-2: compression with pV= constant, from p1=1 bar, V1=1.6m3 to V2=0.2m3,U2U1=0 Process 2-3: constant pressure to V3=V1 Process 3-1: constant volume, U1U3=3549kJ There are no significant changes in kinetic or potential energy. Determine the heat transfer and work for Process 2-3, in kJ. Is this a power cycle or a refrigeration cycle
