Heat transfer Flashcards
Law of Conservation
Energy cannot be created or destroyed just transformed (under normal conditions)
Heat
Thermal energy that flows due to a difference in temperature. Heat flows from hot to cold
Heat transfer
A method by witch heat flows. ( conduction,convection,radiation)
Conduction
Heat transfer within or between solid objects
convection
Heat transfer into or out of fluids
radiation
Heat transfer due to packets of energy called photons that travel through many substances,even empty space
Insolatore
A material through witch energy (electrical, thermal,and sound) cannot easily transfer
Conductor
A material through witch energy (electrical, thermal, sound) can be easily transferred
Temperature
The measure of the average speed of all the particles
Thermal Energy
The total energy of all the particles in an object
