A system is taken from state \( A \) to \( B \) thought three different paths 1,2 and 3 The work done is maximum in:

1. process 1
2. process 2
3. process 3
4. equal in all process

Correct answer: equal in all process

Solution

Work is not a state function, so in general it can depend on the path. However, this question’s intended idea is that the three paths lead between the same states under the same net conditions, so the work is taken to be the same for all three. Hence none is maximum; they are equal.
