== Aluminum foil absorbs heat because the foil, like anything else, will absorb energy from a heat source according to thermodynamic principles. What that translates into is this: heat goes from where it is to where it isn't, or heat goes from where it's hot to where it's not. There are three ways for that to happen. One is convection, one is radiation and the third is conduction. If foil is exposed to flame, the hot combustion gases directly heat the foil when they come in contact with it. If the foil is sitting on the top of the range when the oven is on, the oven heats the air around it and convection currents are set. These convection currents take heat away from the oven and transfer it to things which the hot air passes over. Anyone who has had a hair dryer pointed at them knows what this is like. The skin reacts to the hot air. We feel it. Convection. In a situation where the foil is exposed to radiant energy, infrared radiation, it will react to the incoming radiation by absorbing some of it. Radiation happens because something that is hot is generating heat radiation (electromagnetic waves that are below the optical or visible spectrum). And the foil catches some of them without reflecting them. It absorbs the energy and gets warmer. The best "life experience" example of this kind of radiation may be something familiar. If we suffer a sunburn on our face, the skin is sensitized to heat by the trauma. If we wander into the kitchen where things are cooking on the stove top and look at the stove from fairly close, we might notice a bit of pain where we were burned. That's direct heat (infrared) radiation striking the skin of the face. Another example might be looking into a fireplace through a glass screen. If the fire is hot and we are close enough, we can feel the heat on our face because a bunch of infrared radiation makes a direct route from the fire through the glass and onto our skin. Conduction is the transfer of heat in matter that is touching; for example, from one end of a metal bar to the other end, or from a metal bar that is touching another metal bar.
People say it doesnt absorb heat because when the light points at the foil it bounces back.Also some people say it does absorb heat,but the heat cools down fast
no because aluminum foil is a metal
No, it really reflects heat.
Things do not conduct cold, they conduct heat. Being a metal aluminum foil is both a good conductor of heat and electricity.
answ2. Heat is not 'attracted' 'repelled' by anything.Polished aluminum foil will, and thus is a thermal insulator.Aluminium metal itself is a good conductor of heat.It will reflect the sunlight and retain the heat.

Aluminum foil.
no because aluminum foil is a metal
Aluminumm foil paper keeps many things warm. It keeps things warm because instead of absorbing the heat that wants to get into the material you wrapped foil paper on, the foil paper refelcts back so that the heat does not absorb into the object or material.
No, it really reflects heat.
yes it does
Heat conduction and heat tolerance.
aluimum foil

yes
aluminum foil melt butter faster than a spoon because aluminum foil collects heat faster than a spoon
the aluminum insulates the heat and keeps it in there so no heat to get out if so only a little will
