Answer» hope this help heres the answer mark as brianlistExplanation:Convection is HEAT transfer by mass MOTION of a fluid such as AIR or water when the heated fluid is caused to move away from the SOURCE of heat, carrying energy with it. Convection above a hot surface occurs because hot air expands, becomes less DENSE, and rises (see Ideal Gas Law). |
