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