aluminum has a special substance of atoms in it. they fight against heat and cold, because aluminum expands/contracts more than any metal. it does not want that to happen, so the atoms will fight back against heat change.
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.
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.
It isn't. When in contact it has a high transfer rate. It is a decent reflector though, which in some cases can be used for insulating purposes..
Yes it is a good insulator
Rubber is an object that is a good insulator.
No. Aluminum is a very good conductor of heat.
yes
No, it is not an insulator.

Aluminum is not a good insulator because it is a metal with high thermal and electrical conductivity. This means it allows heat and electricity to flow through it easily, rather than resisting or insulating against it. As a result, aluminum is often used for conducting heat or electricity, rather than insulating against them.
Insulator
Aluminum is a good conductor of electricity. This means that an aluminum fence would conduct electricity rather than insulate against it.

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.
Styrofoam is a better insulator than aluminum because it is less conductive of heat due to its air-filled pockets that slow the transfer of heat. Aluminum is a good conductor of heat, so it allows heat to pass through more easily compared to Styrofoam.
No, aluminum is a good conductor of electricity due to its ability to carry electric current. It is commonly used in electrical wiring and other electrical applications.
Oxygen. Carbon as diamond is a good electrical insulator, (graphite is an electrical conductor), silicon is a semiconductor so has limited electrical conductivity and aluminium is a metal and a good electrical conductor.
