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 processes I and II respectively, then the relation between \(\Delta U_1\) and \(\Delta U_2\) is
- A \(\Delta U_1=\Delta U_2\)
- B \(\Delta U_2 < \Delta U_1\)
- C \(\Delta U_2>\Delta U_1\)
- D undetermined
Answer & Solution
Correct Answer
(A) \(\Delta U_1=\Delta U_2\)
Step-by-step Solution
Detailed explanation
Internal energy is a state function, i.e. it depends upon initial and final state. Hence, it does not depend upon the path chosen. Since, initial and final states are same, so \(\Delta U_1=\Delta U_2\)
