Answer:
The total kinetic and potential energies of its particles
The thermal energy of an object is the:
D. the total kinetic and potential energies of its particles
What is thermal energy?
Thermal energy is the sum of the kinetic and potential energy of all the particles in an object.
Examples are Exothermic chemical reactions, such as oxidation, which convert the potential energy of the materials into thermal kinetic energy, thus increasing the resulting temperature.
Thus, option D is correct.
