Match the correct definition with the correct term from questions 10-13: A. Internal energy B. Latent heat C. Chemical (bond) energy D. Nuclear energy 10. The internal energy associated with the atomic bonds in a molecule. 11. May be viewed as the sum of the kinetic and potential energies of the molecules 12. The internal energy associated with the bonds within the nucleus of the atom itself 13. The internal energy associated with the phase of a system.

Answer: A. Internal energy : May be viewed as the sum of the kinetic and potential energies of the molecules

B. Latent heat: The internal energy associated with the phase of a system.

C. Chemical (bond) energy : The internal energy associated with the atomic bonds in a molecule

D. Nuclear energy : The internal energy associated with the bonds within the nucleus of the atom itself

Explanation:

Internal energy is defined as the total energy of a closed system. Internal energy is the sum of potential energy of the system and the kinetic energy of the system. It is represented by symbol U.

Latent heat is the thermal energy released or absorbed by a thermodynamic system when the temperature of the system does not change. It is thus also called as hidden heat.

Chemical energy is the energy stored in the bonds of molecules.

Nuclear energy is the energy which is stored in the nucleus of an atom called as binding energy within protons and neutrons.
