Question

The idealized P-V diagram above shows a complete cycle through compression and expansion of a gas. The questions below relate to the processes within the cycle.
Which letter shows work done?

• A. A
• B. B
• C. C
• D. D
• E. E

Answer 1

The correct option is E E

Here the work done will be the area under the pressure-volume curve. The work done under the part A will be positive work, but the negative work done under the part C must be subtracted. Thus the leaving work as E as shown in diagram. Thus, option E will be correct.
