heat transfer Flashcards
law of conservation of energy
energy cannot be created o destroyed just transformed
heat
the thermal energy that flows due to a difference heat flows from hot to cold
heat transfer
a method by wicth 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
a material through which energy (electrical thermal or sound) cannot be easily transfered
conductor
a material through which energy (electrical thermal or sound) can be easily transferd
temperature
the measure of the average speed of all particels
therml energy
the total energy of all particles in am object
