Energy and 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 diference in temperature. Heart flows from hot to cold.
Heat
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
Air/water
Convection
Heat transfer due to packetsa 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) Can be easily transferred.
conductor
THe mesure of the avarage speed of all particals.
Temperature
The measure of the average speed of all particles.
