That is, the capacity to move matter or supply heat. Energy exists in different forms which can be interconverted. Joule 1 Joule of energy is about the energy needed for 1 heartbeat. Heat is the transfer of thermal energy from one object to another because they are at different temperatures. Heat is a method of energy transfer from a hot object to a cold one.
Thermal energy is the energy associated with the random motion of the atoms and or molecules.
The Kelvin temperature is related to the constituent particles' average molecular kinetic energy. Temperature change is a change in the average kinetic energy of an object. Law of Conservation of Energy - Energy can be converted from one form to another, but the total quantity of energy is assumed to remain constant in ordinary processes. The study of the quantity of heat absorbed or given off by chemical reactions. All chemical reactions either give off or absorb energy.
