Kinetic energy is the sum of:
Correct answer: C. Rotational, vibrational and translatio
- A. Rotational & vibrational
- B. Translation & rotational
- C. Rotational, vibrational and translatio
- D. All of these
Explanation
Kinetic energy is the sum of translational, rotational, and vibrational kinetic energies, representing the various forms of motion exhibited by the particles within an object. Each of these forms of motion contributes to the object's total kinetic energy.

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.
