2.46 WP A gas contained in a piston-cylinder assembly undergoes two processes, A and B, between the same end states, 1 and 2, where P₁ = 1 bar, V₁ = 1 m³, U₁ = 400 kJ and p₂ = 10 bar, V₂ = 0.1 m³, U₂ = 450 kJ: Process A: Constant-volume process from state 1 to a pressure of 10 bar, followed by a constant-pressure process to state 2. Process B: Process from 1 to 2 during which the pressure- volume relation is pV = constant. Kinetic and potential effects can be ignored. For each of the processes A and B, (a) sketch the process on p-V coordinates, (b) evaluate the work, in kJ, and (c) evaluate the heat transfer, in kJ.
