heat transfer Flashcards
(11 cards)
Law of conservation
energy cannot be created or destroyed just transferred (under normal conditions)
Heat
The thermal energy that flows due to a difference in temperature heat flows from hot to cold.
heat transfer
A method by 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 can travel through many substances even empty space.
insulator
Material with energy (electrical, thermal, sound) cannot be easily transferred.
conductor
Material with energy (electrical, thermal, sound) can be easily transferred.
insulator
Material with energy (electrical, thermal, sound) cannot be easily transferred.
temperature
The measure of the average speed of all particles.
Thermal energy
The total energy of all particles in an object
