WebWhen you hold your hand over the stove (not touching it), you can feel the heat. The air above the stove is heated and because it is a gas, moves upward. This is convection. The bottom of the pot and the surface of the stove are not 100% flat. That's why there will be little pockets of air underneath the pot, even if you place it on the stove. WebHeat Convection 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).Hot water is likewise less dense than cold … alla run
