Thermal energy flow.
q = C T
By Kinetic Theory, T is proportional to kinetic energy (& q).
By Quantum Theory, heat associates with changes in energy level populations.
Organized rather than chaotic molecular motion.
Comes in many forms.
By Quantum Theory, work associates with changes in the energy levels themselves.
