Energy and Heat Transfer Vocabulary Flashcards
Law of Conservation of Energy
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 Transfers
A method which heat flows ( conduction, convection, and radiation).
Conduction
Heat transfers within or between solid objects.
Convection
Heat transfers into or out of fluids.
Radiation
Heat transfers due to packets of energy called photons that can travel through many substances, even empty spaces.
Insulator
A material which energy (electrical, thermal or sound) cannot be transferred easily.
Conductor
A material through which energy (electrical, thermal or sound) can be easily transferred.
Temperature
The measure of the average speed of all particles.
Thermal Energy
The total energy of all particles in an object.
