A gas inside a piston-cylinder assembly undergoes a

A gas inside a piston-cylinder assembly undergoes a refrigeration cycle consisting of these three processes: Process 1-2: Compression with pV = constant from p₁ = 1 bar, V₁ = 1 m³, to p₂ = 10 bar, V₂ = 0.1 m³. Process 2-3: Constant volume heating until P3 = P₁. Process 3-1: Constant-pressure, adiabatic expansion. There are no changes in kinetic or potential energy. a) [3 pts] Find the work for process 1-2 in kJ. b) [3] Find the work for process 2-3 in kJ. c) [3] Find the work for process 3-1 in kJ. d) [2] Find the net work for the entire cycle in KJ. e) [3] Find the net heat transfer for the entire cycle, in kJ. f) [3] Find the heat transfer for process 3-1 in kJ. g) [3] Knowing Q12 = -100 kJ, find the heat transfer for process 2-3 in kJ.
