Question

An ideal gas can be expanded from an initial state to a certain volume through two different processes: (a) P V 2 = K and (b) P = K V 2 , where K is a positive constant. Then, choose the correct option from the following.

(a) V n RT ​ ⋅ V 2 = K ⇒ T V = const, so T ∝ V 1 ​ : temperature falls on expansion. (b) V n RT ​ = K V 2 ⇒ V 3 T ​ = const, so T ∝ V 3 : temperature rises on expansion. Hence the final temperature is greater in (b).
