Zeroth Law of Thermodynamics
States that two objects that are in thermal equilibrium with a third object are also in thermal equilibrium with each other. By extension, objects at the same temperature are in thermal equilibrium with no net transfer of heat.
Conduction
Form of heat transfer where energy is transferred by molecular collisions or direct contact between two objects.
Convection
Form of heat transfer where a heated fluid transfers energy by bulk flow and physical motion over another object, or a cooled fluid absorbs energy by the same means.
Heat Transfer
The movement of thermal energy towards a state of thermodynamic equilibrium. Heat spontaneously transfers energy from the object with the higher temperature to the object with the lower temperature.
Radiation
Form of heat transfer where the energy is carried by electromagnetic waves; the only form of heat transfer that can be carried out in a vacuum.
