JEE Main2026Jan 21, Shift 1Chemistry
Q.

Which of the following graphs between pressure 'P' versus volume 'V' represent the maximum work done?

  1. A

  2. B

  3. C
  4. D
Solution

Work done in a P-V process equals magnitude of area under the P-V curve. Option (2) has zero work (isochoric). Option (4) has the largest area — maximum work magnitude. (NTA reported answer ignores sign convention.)
