Heat Transfer Flashcards
Law of Conservation of Energy
Energy cannot be created or destroyed only transformed.(Under normal conditions)
Heat Transfer
A method by which heat flows.(conduction,convection,radiation)
Heat
Thermal energy that flows due to a difference in temperature.
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 can travel through many substances, even empty space.
Insulator
A material which energy (electrical, thermal, or sound) cannot be easily transferred.
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.
