Question

Curves in the given P–V diagram represent isotherms. There are three states A, B, C of an ideal gas.

Statement-1: As the ideal gas is taken from A to B to C along a process represented by straight line ABC its temperature first increases and then decreases.

Statement-2: Along isotherms as pressure increases volume decreases.

TestHub · Accepted Answer

B lies on a higher isotherm than A and C, so along straight line ABC the temperature rises then falls: S-1 true. Along an isotherm P V = const , so increasing P decreases V : S-2 true, but it is not the explanation of S-1.
