Vedclass · Answer

(D) The $Assertion$ is incorrect. Two isothermal curves for different temperatures cannot intersect each other. If they were to intersect at a point,it would imply that at that specific $(P, V)$ state,the system has two different temperatures simultaneously,which is impossible.The $Reason$ is correct. An isothermal process is a slow process that allows the system to remain in thermal equilibrium with its surroundings. The slope of an isothermal curve on a $P-V$ diagram is given by $-\frac{dP}{dV} = \frac{P}{V}$. Since $P$ and $V$ are positive,the slope is finite and relatively small compared to adiabatic curves (which have a slope of $\gamma \frac{P}{V}$).

$Assertion :$ The isothermal curves intersect each other at a certain point.
$Reason :$ The isothermal change takes place slowly,so,the isothermal curves have very little slope.
