A system goes from

A

and

B

via two processes

I

and

II

as shown in figure. If

\Delta {U_1}

and

\Delta {U_2}

are the changes in internal energies in the process

I

and

II

respectively, then

View answer and explanation

Correct option: A

\Delta {U_1} = \Delta {U_2}

Option A (

\Delta {U_1} = \Delta {U_2}

) is correct because the change in internal energy is a state function and depends only on the initial and final states, not the path taken.
