A system is taken from state to thought three different paths 1,2 and 3 The work
A system is taken from state \( A \) to \( B \) thought three different paths 1,2 and 3 The work done is maximum in:
- A. process 1
- B. process 2
- C. process 3
- D. equal in all process
Step-by-step solution
Work done in a thermodynamic process is given by the area under the P-V curve. Typically, for three different paths from A to B, the path with the largest area under the curve does the maximum work. In standard problems, process 2 often represents the reversible isothermal expansion, which yields the maximum work compared to other irreversible paths. Hence, process 2 is the correct choice.
