i think it is a insulator
It is a heat and electricity conductor.
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.
Yes. Aluminium is a very good conductor of electricity, and works with salt water.
This foil is also a metal.
It is an insulator.
ummm...Yeah....With foil
no
Foil is considered to be a good insulator since it has the ability to reflect radiation. However, aluminium foil is commonly used as a conductor and not an insulator.
What is floil? Do you mean aluminum foil? If so, metals conduct heat fairly well.
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.
Aluminium foil is a type of metal. All metals are good conductors of Heat.
It is an isulator as it allows thethe current to pass through it ...
Both sapphire and ruby are a crystallized form of the compound aluminium oxide which is a good insulator.
One electrical conductor is gold. An insulator would be rubber as it is what keeps people from getting electrocuted on wires A thermal conductor can be any metal. A thermal insulator is tin foil.
Gold: Insulator* Wood: Insulator Tin: Conductor Plastic: Insulator Cotton: Insulator* Silver: Insulator* Wool: Insulator* Aluminium: Conductor Copper: Conductor Iron: Conductor Rubber: Insulator Air: Insulator* All answers that I have marked with an asterisk (*) are answers that I am pretty sure about but not entirely 100% positive. Not all my answers will be correct but I am fairly sure most of them are. :)
Aluminum foil can be use as both insulator and conductor. It can wrap and trap air inside cause thermal insulating effect but in other hand, aluminum itself is a conductor for evenly distribution of heat throughout the food. Aspect of substance fabricated is different from an insulation conduction aspect of a substance.
a conductor attracts and an insulator keeps it all together
