JEE Main 2025 — 2 April, Evening Shift — Question 1

Arrange the following in order of magnitude of work done by the system/on the system at constant temperature. (a) $\mid$ Wreversible| for expansion in infinite stages (b) |Wirreversible for expansion in single state (c) $\left|W_{\text {reversible }}\right|$ for compression in infinite stages (d) |Wirreversible| for compression in single stage Choose the correct answer from the options given below.

Option A:
$c=a>d>b$
Option B:
$d>c=a>b$
Correct
Option C:
$a>c>b>d$
Option D:
$a>b>c>d$

Answer: B

Step-by-step solution

$\left|W_{\text {reversible expansion }}\right|>\left|W_{\text {irreversible expansion }}\right|$

$\left|W_{\text {reversible expansion }}\right|=\mid W_{\text {reversible }}$ compression $\mid$

$\mid$ Wirreversible compression $|>|$ Wreversible compression|
