A system goes from A to B via two processes I and II shown in the figure. If Δ U 1 and Δ U 2 are the changes in internal energies in the processes I and Il respectively

Options

  1. AΔ U 1 = Δ U 2
  2. BΔ U 1 > Δ U 2
  3. CΔ U 1 < Δ U 2
  4. DΔ U 1 ≠ Δ U 2

Correct answer

A. Δ U 1 = Δ U 2

Step-by-step solution

The process in which the initial and final state is the same is known as a cyclic process. It is a sequence of processes that leave the system in the same state in which it started. Change in internal energy is independent on path, it depends on only initial and final state. So changes in internal energies for both process will be same.
