A system undergoes a two-step process as sketched in Figure P16.21. The system first expands at constant pressure from state I to state A and then it is compressed with the pressure again held fixed, ending with the system in state f. What is the approximate amount of work done by the system during each step?

Figure P16.21

20,000 i 10,000 0.1 0.2 V (m³) P (Pa)

20,000 i 10,000 0.1 0.2 V (m) P (Pa)
