Vedclass · Answer

(C) For an isothermal process, the magnitude of work done during compression is greater than the magnitude of work done during expansion between the same initial and final states.In the case of expansion, the work done in multi-stage expansion $(w_B)$ is greater than in single-stage expansion $(w_A)$, so $|w_B| > |w_A|$.In the case of compression, the work done in single-stage compression $(w_C)$ is greater than in multi-stage compression $(w_D)$, so $|w_C| > |w_D|$.Comparing the two, the magnitude of work required for compression is always greater than the magnitude of work obtained during expansion between the same two states.Therefore, the correct order of magnitude is $|w_C| > |w_D| > |w_B| > |w_A|$.

List-$I$ (Isothermal process)	List-$II$ (Expression)
$A$. Reversible expansion	$I$. $q = 0$
$B$. Free expansion	$II$. $q = nRT \ln \frac{V_2}{V_1}$
$C$. Irreversible Compression	$III$. $w = -P_{ext}(V_1 - V_2)$
$D$. Cyclic reversible	$IV$. $\frac{q_{rev}}{T} = 0$

Arrange the following isothermal processes in order of the magnitude of the work $(w)$ involved between states $1$ and $2$.
$A$. Expansion in single stage $(w_A)$
$B$. Expansion in multi stages $(w_B)$
$C$. Compression in single stage $(w_C)$
$D$. Compression in multi stages $(w_D)$
