Question

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

Quantrex Academy · Accepted Answer

Correct answer: A. Q₁>Q₂>Q₃ and U₁= U₂= U₃

For all processes 1,2 and 3 Change in internal energy, i.e. gathered U=U_B-U_A U₁= U₂= U₃ Q= U+ W gathered Now, W= work done by the gas, i.e. area under p-V curve. As, area (1)> area (2)> area (3) array ll & W₁> W₂> W₃ & Q₁>Q₂>Q₃ array
