Refer to figure. Let `DeltaU_(1)` and `DeltaU_(2)` be the changes in internal energy of the system in the processes A and B. then

Options

A. `Delta U_(1) gt Delta U_(2)`
B. `Delta U_(1)= Delta U_(2)`
C. `Delta U_(1) lt Delta U_(2)`
D. `Delta U_(1) != Delta U_(2)`

Answer

B

Explanation

As `Delta U` is a state function i.e., it depends initial and final position in process `A` and `B` and final temp are same.
`:. Delta U_(1)=Delta U_(2)`
