Energy & Heat Transfer Flashcards
Energy cannot be created or destroyed just transformed (under normal conditions).
Law of Conservation of Energy
Thermal energy that flows due to a difference in temperature. Heat flows from hot to cold.
Heat
A method which heat flows (conduction, convection, radiation).
Heat Transfer
Heat transfer within or between solid objects.
Conduction
Heat transfer into or out of fluids.
Convection
Heat transfer due to the packets of energy called photons that can travel through many substances, even empty space.
Radiation
A material through which energy (electrical, thermal, or sound) cannot be easily transferred.
Insulator
A material through which energy (electrical, thermal, or sound) can be easily transferred.
Conductor
The measure of the average speed of all particles.
