Heat Transfer Flashcards
Energy cannot be created or destroyed, just transformed (under normal circumstances)
Law of Conservation of Energy
Thermal energy that flows due to a difference in temperature. Heat flows from hot to cold
Heat
A method by which heat flows (conduction, convection, radiation).
Heat Transfer
Heat transfer within or between solid objects
Conduction
Heat transfer into or out of fluid
Convection
Heat transfer due to 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 transfered,
Insulator
A material at which (electrical, thermal, or sound) can be easily transfered
Conductor
A measurement of the average speed of all particles
Temperature
The total energy of all particles in an object
