In case of a reversible process (following pvn = constant), work obtained for trebling the volume (v1 = 1 m3 and v23 m3) is maximum, when the value of 'n' is_________________?
Correct answer: A. 0
- A. 0
- B. 1
- C. y = 1.44
- D. 1.66
Explanation
With the initial pressure fixed, work is maximised by maintaining the highest possible pressure during expansion, which corresponds to n = 0 and therefore constant pressure. Larger n values make pressure fall as volume increases, reducing the area under the p-V curve.

The more specific you are, the faster it gets fixed. A source beats an opinion.
