In fact, many mirrors are actually a film of aluminum deposited
on the back of a sheet of glass. So yes, aluminum foil does reflect
'like a mirror'. The reflectivity of most common aluminum alloys is
in excess of 98%, in both the visible and infrared ranges of light.
There is no such thing as "transfer of cold". Only heat can be transmitted. If it seems that "cold" is transmitted from a cold object to a hot one, it really works the other way - the heat (for example, in the form of infrafred radiation) goes from the hot object to the cold object.
Yes it does. This is due to the electrons in the outer shells of metals; they cause reflection.
it reflects sunlight because the speacil supstance that it is made from does not absorb heat so it reflects it and it get hot
Cold is an absence of heat. Aluminum is a metal, and conducts heat. Shiny foil will reflect some heat, so it can help keep cold things cold, but not as well as other materials.
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.
Yes, it is true.
no
It depends on the thickness of aluminium and also depends on the nature of light. If the Aluminium foil is very thin, then the light may transit small extent. But, in general, the visible light gets reflect.
Light reflects when it hits aluminum foil. In fact, anything that you can see reflects light. Without the reflecting light reaching your eyes, you would not see it at all.

aluminum foil is better at blocking temperature from getting out than plastic wrap. the atoms in the element aluminum are bigger and have more neutrons/electrons and protons than the elements in plastic wrap.

Yes all metal foils reflect heat (and other electromagnetic radiation: light, radio waves, etc.).
Aluminum is element. Aluminum foil is made entirely of aluminum.
No. The wire rack does not have enough surface area to cause a problem.. The foil is a solid surface and will reflect the microwaves.
The aluminum foil reflected the rays of the light, so without the foil the ice cube couldn't reflect any of the light's rays and that made it melt faster
Aluminum foil is made of Aluminum, which is an element. So yes Aluminum foil is a element
Tin foil... tin Aluminum foil... aluminum :)
