A system goes from A and B via two processes. I and II as shown in figure. If `DeltaU_1 and DeltaU_2` are the changes in internal energies in the processes I and II respectively, then

A

`DeltaU_(1)=DeltaU_(2)`

B

relation between `DeltaU_(1) and DeltaU_(2)` cannot be determined

C

`DeltaU_(2) gt DeltaU_(1)`

D

`DeltaU_(2) lt DeltaU_(1)`

Text Solution

Verified by Experts

The correct Answer is:
A
`DeltaUto`depends on initial and final state
`DeltaU_(1)=DeltaU_(2)=U_(B)-U_(A)`.
