Question: An ideal gas undergoing a change of state from A to B through four different paths I, II, III and IV...
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
A
Is same in I and II but not in III and IV
B
Is same in III and IV but not in I and II
C
Is same in I, II and III but not in IV
D
Same in all the four cases
Answer
Same in all the four cases
Explanation
Solution
: from the given initial state A to final state B. change in internal energy is same all the four cases, as it is dependent of the path from A to B
