Question

find the word that matches the definition: sum of the kinetic energies of all the particles that make up an object

Explanation:

Thermal energy is the sum of the kinetic energies of all the particles that make up an object. A thermal insulator is a material that resists the transfer of heat. Convection is the transfer of heat through the movement of fluids (liquids or gases). Conduction is the transfer of heat through direct contact between materials.

Answer:

thermal energy
