Which of the following statements does not correspond to the First law of Thermodynamics?
Correct answer: D. All the above statements are correct.
- A. Energy can neither be created nor destroyed.
- B. A system may lose energy but that energy will go to the surroundings to increase.
- C. The total energy of the system and its surroundings remains constant.
- D. All the above statements are correct.
Explanation
The correct answer is Option D: All the above statements are correct. This option is correct because statements A, B, and C all accurately describe aspects of the First Law of Thermodynamics. Statement A highlights energy conservation, statement B explains the energy exchange between a system and its surroundings, and statement C emphasizes the constancy of total energy. Since the question asks for a statement that does not correspond to the First Law, and all provided statements do correspond, Option D correctly identifies this situation.

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.
