Energy and Heat Transfer vocab Flashcards
Energy cannot be created or destroyed just transformed (under normal conditions).
Law of conservation 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
A heat transfer within between solid objects
conduction
A heat transfer into or out of fluids
Convection
Heat transfer due to the ppockets 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 transformed.
Insulator
A material through which energy ( electrical, thermal, or sound) cannot be easily transformed.
Conductor
The measure of the average speed of all particles
Temperature
The total energy of all particles in an object
Thermal energy
