Any metal is a terrible insulator of heat. Wallpaper would be much better.
Aluminum foil is a better heat insulator than newspaper. Aluminum foil reflects thermal energy, while newspaper absorbs and conducts heat. Therefore, aluminum foil will help keep heat in or out more effectively.
No, cotton is not a better insulator than aluminum foil and tissue paper. Aluminum foil is a good insulator as it reflects heat, while tissue paper acts as a thermal barrier. Cotton, on the other hand, is not as effective of an insulator because it does not have the same reflective or thermal barrier properties.
i think it is a insulator
What we usually refer to as tin foil is almost always aluminum foil. Aluminum is a very good conductor of heat, and aluminum foil makes a very poor insulator. The exception might be in the case of radiant energy, which it reflects well, and even better when it is polished.
Insulator or conductor depending on the circumstances. Aluminum foil conducts heat, but it cuts off air flow and reduces evaporation of fluids. Aluminum foil reflects and thus minimizes radiation transmission. With foods it is more useful as an insulator. It also acts as an insulator on windows. But, aluminum is definitely a good heat conductor.
because it conducts heat very well.
Uh...No. And neither is a toaster. An insulator is something like cardboard or reflective foil, it keeps the heat in and the cold out :)
What is floil? Do you mean aluminum foil? If so, metals conduct heat fairly well.
aluimum foil
it is actually a conductor of heat and electricity. you can check by puting some foil on a piece of toast on a really hot day and if you wait a while it will turn into crispy toast.
Styrofoam is a better insulator of heat than plastic. The plastic allows the heat in and out and the cold in and out. The Styrofoam helps keep the heat in.
A metallic foil (from gold, silver, copper).
