For a change in state from A to B.
Correct answer: B. E depends only on the initial and final state
- A. q depends only on the initial and final state
- B. E depends only on the initial and final state
- C. w depends only on initial and final state
- D. E depends upon path adopted to state go from A to B.
Explanation
The internal energy of a system is a state function, which means that it depends only on the initial and final state of the system. The amount of internal energy of a system does not depend on the path that the system takes from the initial state to the final state.

About Thermochemistry and Energetics of Chemical Reactions
Thermochemistry measures energy changes in chemical reactions and distinguishes exothermic from endothermic processes. Work covers systems, surroundings and state functions, internal energy, the first law of thermodynamics, enthalpy and Hess's law, including the sign conventions used when heat enters or leaves a system.
