Vedclass · Answer

(D) For an isothermal process,the equation of state is $PV = 	ext{constant}$.If two isothermal curves were to intersect,it would imply that at the point of intersection,the system has two different temperatures simultaneously,which is physically impossible.Therefore,the Assertion is incorrect.For an isothermal process,the slope of the $P-V$ curve is given by $\frac{dP}{dV} = -\frac{P}{V}$.Since the process occurs slowly,the system remains in thermal equilibrium,but the slope depends on the values of $P$ and $V$,not just the speed of the process.Thus,the Reason is also incorrect.

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.
