If heat is motion, why do fans cool you off?
My guess is that if you had a closed room (so no air goes in or out, but obviously energy would be coming in from the fan) then the fan actually would heat up the room on average.
My guess is that fans only create some kind of apparent coolness, or maybe the motion of air somehow "collects" and "takes away" the heat from your body, so you feel cooler, even though the room (as a whole) is warmer.
Any explanations?
