What is the relationship between heat and thermal energy?

Thermal energy is an equation of state, it is the total energy contained in a system due to the random motions of all of its constituents (in the center of mass frame). Heat is energy in transport, and it is not an equation of state. It is the energy transferred from one system to another that is not done by work. read more

Heat is what is given of from thermal energy. Thermal energy is what is given off when energy is lost. Because according to the Law of Conservation of Energy: Energy can neither be created nor destroyed, but transferred to a lesser form. read more

Temperature is a measure of the amount of heat energy an object has. As per the second law of thermodynamics, heat flows from hotter objects to colder objects. read more
