A gas contained in a piston-cylinder assembly undergoes two processes, $\mathrm{A}$ and $\mathrm{B}$, between the same end states, 1 and 2, where $p_1=1$ bar, $V_1=1{\mathrm{m}}^3,U_1=400\mathrm{kJ}$ and $p_2=10\mathrm{bar},V_2=0.100{\mathrm{m}}^3,U_2=450\mathrm{kJ}$ : Process A: Constant-volume process from state 1 to a pressure of $10\mathrm{bar}$, 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) evaluate the work, in kJ, and (b) evaluate the heat transfer, in kJ. Part A Your answer is incorrect. For Process A, evaluate the work and the heat transfer, both in $\mathrm{kJ}$.
