The reason that some materials are good conductors (of electricity) is because the outer electrons of the atomic nucleus are easily pulled away by an electric charge and if you keep applying that charge (such as with a battery) a current will flow. A good conductor is just the same as a bad insulator.

Why is tinfoil a good insulator?
It actually isn't a good insulator. Tin foil and aluminum are good conductors, not insulators.
Is a foil an insulator or conductor?
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.
How Does aluminum foil prevent energy loss by radiation?
Aluminum foil is a conductor of heat energy. However, it does reflect radiation from heat sources, so it can reduce heat transfer through radiation. When aluminum foil is wrapped around something, pockets of air can be trapped. Trapped air is an excellent insulator against conduction and convection. However, if you want to prevent something like a can of soda from getting warm in your lunchbox, a wool sock will be a better insulator. Even paper toweling is better at insulating than aluminum foil when light is not shining.
Is aluminum foil an insulator or a conductor of heat?
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.
Is aluminum foil a better heat conductor than metal?
no because aluminum foil is a metal
Is aluminum foil a conductor or insulator?
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.
How do the different types of insulators affect the temperature of the can Out of Steel Wool Aluminum Foil Cotton and Bubble Wrap which one would be the best insulator?
If I had to choose the best insulator out of steel wool, aluminum foil, cotton and bubble wrap, I would choose the aluminum foil.
Why is tinfoil a good insulator?
It actually isn't a good insulator. Tin foil and aluminum are good conductors, not insulators.
Is tin foil a good 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.
Can aluminum foil be used under laminate flooring to act as an insulator?
yes
Is aluminum foil the best insulator?
yes it is because it traps the coolness inside.
Is cotton a better insulator than aluminium foil and tissue paper?
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.
Which material makes a better heat insulator newspaper or aluminum foil?
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.
Which is the best insulator stira foam card board aluminum foil or a plastic container?
stira foam is a better insulator because it will keep it warm
Is floil an insulator or a conductor?
What is floil? Do you mean aluminum foil? If so, metals conduct heat fairly well.
Is aluminum foil an insulator or a conductor?
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.
Which keeps things colder plastic wrap or aluminum foil data?
It would definitely have to be plastic wrap because plastic wrap is an insulator, which aluminum is not.
