An ideal gas undergoes a cyclic transformation starting from the point A and coming back to the same point by tracing the path $\displaystyle \mathrm{A} \rightarrow \mathrm{B} \rightarrow \mathrm{C} \rightarrow \mathrm{D} \rightarrow \mathrm{A}$ as shown in the three cases above.
Choose the correct option regarding $\displaystyle \Delta \mathrm{U}$ :Official answer
From NTA’s final answer key for this paper.
(4)
$\displaystyle \Delta \mathrm{U}(\text { Case-I })=\Delta \mathrm{U}(\text { Case-II })=\Delta \mathrm{U}(\text { Case-III })$
