The internal energy change when a system goes from state A to B is $40$ kJ/mole. If the system goes from A to B by a reversible path and returns to state A by an irreversible path what would be the net change in internal energy?

  1. $40$ kJ
  2. $> 40$ kJ
  3. $< 40$ kJ

  4. Zero
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
For a cyclic process the net change in the internal energy is zero because the change in internal energy doesnot depend on the path.
