Question

An ideal gas goes from state A to state B via three different processes A as indicated in the p $$-V$$ I diagram lf $$Q1$$, $$Q2$$, $$Q3$$ indicate the heat absorbed P by the gas along the three processes and ∆$$U1$$, ∆$$U2$$, ∆$$U3$$ indicate the change in internal energy along the three processes respectively, then

For all processes $$1$$,$$2$$ $$arrd3$$∆U $$=$$ $$UB-UA$$ is the same∴ ∆$$U1$$ $$=$$ ∆$$U2$$ $$=$$ ∆$$U3Now$$, Q $$=$$ ∆U $$+$$ WNow, W $$=$$ work done by the gas∴  $$Q1$$ > $$Q2$$ > $$Q3$$
