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 tyhen the change in internal energy is

A

same in I and II but not in III and IV

B

same in III and IV but not I I and II

C

same in I, II and III but not I IV

D

same in all the four cases

Text Solution

Verified by Experts

The correct Answer is:
D
From the givne initial stte A to final state B, change in internal energy is same all the four cases as it is independent of the path from A to B .
