STATEMENT-1 : The magnitude of the work involved in an isothermal expansion is greater than that involved in an adiabatic expansion. STATEMENT2 : $P-V$ curve ( $P$ on $y$-axis and $V$ on $x$-axis) decrease more rapidly for reversible adiabatic exparision compared to reversible isothermal expansion starting from same initial state.

View answer and explanation

Correct option: A

If both the statements are TRUE and STATEMENT-2 is the correct explanation of STATEMENT-1

Option A is correct. The magnitude of work in isothermal expansion is greater than in adiabatic expansion because the P-V curve decreases more rapidly in adiabatic expansion, meaning less area under the curve and thus less work done. Statement 2 correctly explains Statement 1.
