HEAT TRANSFER Flashcards
(10 cards)
does hot air rise or fall and why?
rise because it is less dense
Does the cold air rise or fall and why?
fall because it is more dense
what is a example of conduction
putting your head to the cool pillow and having the heat from your head transfer to the pillow
what does radiation move in
waves
what are examples of radiation
the sun and a fire transferring heat to the air particles
what is the best place to put a vent
on the floor because the heat will rise and the cool air will sink
if you had a fire how could I push hot air down
put a fan to push the air down
conduction
the process by which heat energy is transmitted through collisions between neighboring atoms or molecules.
convection
the process of transferring heat through air or liquid currents.
radiation
energy that moves from one place to another in a form that can be described as waves or particles.
