Why does aluminum foil never get hot to the touch. You can leave it in the oven and touch it directly out of the oven without it feeling hot. Why is this?
In: Physics
Not only does aluminum change temperature rapidly and lose heat to the air before you can touch it, but a sheet of aluminum foil has very little mass. This means that the total amount of stored heat in the area you touch is very low. This means that even a very hot sheet of aluminum foil can’t transfer much heat into your skin, so you don’t get burned.
