Heat Transfer Flashcards
Law of conversation of energy
Energy cannot be created or destroyed just transformed (under nodrmal circumstances)
Heat
Thermal energy that flows due to a difference in tempature.Heat from hot to cold
Heat Transfer
A method by which heat flows (conduction,convection,radiation).
Conduction
Heat transfer within or between solid objects
Convection
Heat transfer into or out fluids.
Radiation
Heat transfer due to packets of energy called photons that can travel through many substances even empty space.
Insultor
A material through which energy (electrcial 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.
