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 by 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 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.
Temperature
The total energy of all particles in an object
