Internal energy does not include:
Correct answer: D. Rnergy due to gravitation
- A. Vibrational energy
- B. Rotational energy
- C. Translational energy
- D. Rnergy due to gravitation
Explanation
The correct answer is gravitational energy.Internal energy is the total energy of a system, including the kinetic energy and potential energy of all the particles in the system. The kinetic energy of the particles is due to their movement, and the potential energy of the particles is due to their interactions with each other.

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.
