A system goes from A to B via two processes and II as shown in figure. Ifandare the changes in internal energies in the processes I and II respectively, then [AIEEE 2005] |
A) \[\Delta {{U}_{1}}=\Delta {{U}_{2}}\]
B) relation between\[\Delta {{U}_{1}}\]and\[\Delta {{U}_{2}}\]cannot be determined
C) \[\Delta {{U}_{2}}>\Delta {{U}_{1}}\]
D) \[\Delta {{U}_{2}}<\Delta {{U}_{1}}\]
Correct Answer: A
Solution :
[a] The change in internal energy does not depend upon path followed by the process. It only depends on initial and final states. |
