Question

An ideal gas goes from state A to state B via three different processes as indicated in the p − V diagram If Q 1 ​ , Q 2 ​ , Q 3 ​ indicate the heat absorbed by the gas along the three processes and Δ U 1 ​ , Δ U 2 ​ , Δ U 3 ​ indicate the change in internal energy along the three processes respectively, then NEET 2012 (Mains)

For all process 1,2 and 3 ∴ Now, ​ Δ U = U B ​ − U A ​ is same Δ U 1 ​ = Δ U 2 ​ = Δ U 3 ​ Δ Q = Δ U + Δ W ​ Now, Δ W = work done by the gas ∴ Δ Q 1 ​ > Δ Q 2 ​ > Δ Q 3 ​
