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

Options

A. `DeltaU_(||) lt DeltaU_(|)`
B. `DeltaU_(||) lt DeltaU_(|)`
C. `Delta U_(||)=Delta U_(|)`
D. Relation between `DeltaU_(|)` and `DeltaU_(||)` cannot be determined

Answer

C

Explanation

As internal energy is a point function therefore change in internal energy does not depends upon the path followed i.e., `DeltaU_(1)=DeltaU_(11)`.
