Which statement about thermal energy
is most accurate

Thermal energy is the kinetic energy of microscopic agitation of an object, which is due to a disordered agitation of its molecules and atoms. Thermal energy is a part of the internal energy of a body. Transfers of thermal energy between bodies are called thermal transfers and play an essential role in thermodynamics. They reach a balance when the body temperature is equal. The transfer of energy, driven by a difference in temperatures, from one thermodynamic system to another, is called heat.
