Energy and heat Transfer Flashcards
law of conservation
energy can not be created to destroy just transformed( under normal condition)
Heat
the thermal energy that flows due to a difference in temperature. heat flows from hot to cold
heat transfer
method by which heat flows( conduction, convection,radiation)
conduction
heat transfer within or between solid objects
convection
heat transfer into or out of fuluids
radiation
heat transfer due to packets of energy called photons that can travel through many substances, even empty spaces
insulator
a material in which energy (electrical, thermal, or sound) cannot be easily transferred
conductor
A material through which energy ( electrical thermal or sound) can be easily transformed.
temperature
The measure of the average speed of all particles
thermal energy
The total energy of all particles in an object
