STANDARD Physics First Law of Thermodynamics MCQ Question
An ideal gas undergoing a change of state from A to B through four different paths I, II, III and IV as shown in the P-V diagram that lead to the same change of state, then the change in internal energy is
same in I and II but not in III and IV
same in III and IV but not in I and II
same in I, II and III but not in IV
same in all the four cases
Correct Answer
Detailed Explanation
From the given initial state A to final state B, change in internal energy is same for all the four cases, as it is independent of the path from A to B.
