Question

An ideal gas undergoes change in its state from the initial state I to the final state F via two possible paths as shown. Then 

 (A) there is no change in internal energy along path 1 

 (B) heat is not absorbed by the gas in both paths 

 (C) the temperature of the gas first increases and then decreases for path 2 

 (D) work done by the gas is larger in path 1

Answer 1

Correct option (C) the temperature of the gas first increases and then decreases for path 2

Explanation:

ΔP/ΔV is positive for 1^st half & negative for 2^nd half have temperature 1^st increases then decreases.
