A gas contained within a piston-cylinder assembly undergoes two processes

A gas contained within a piston-cylinder assembly undergoes two processes, A and B, between the same end states, 1 and 2, where p₁=10 bar, V₁= 0.1 m³, U₁=400 kJ and p₂=1 bar, V₂=1.0 m³, U₂=200 kJ:

Process A. Process from 1 to 2 during which the pressure-volume relation is p.V = constant.

Process B: Constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to state 2

Kinetic and potential energy 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.
