heat and transfer Flashcards
low of conservation of energy
energy cannot be created or destroyed just transformed under normal conditions
heat
thermal energy that flows due to a difference in temperature heat flows from hot to cold
heat transfer
a method by which heat flows conviction, convection, radiation
conduction
heat transfer within or between solid objects
convection
heat transfer into or out of fluids
radiation
heat transfer due to pockets of energy called photons that can travel through many substances even empty space
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 transferred
temperature
the measure of the average speed of all particles
thermal energy
the total energy of all particles in an object
