10/5/2022· Ans- Let us consider the general case in which a change of state is brought about both by doing work and by transfer of heat. We write change in internal energy for this case as: ∆U = q + w For a given change in state, q and w can vary depending on how the change is carried out. However, q +w = ∆U will depend only on initial and final state.
