If I had to choose the best insulator out of steel wool, aluminum foil, cotton and bubble wrap, I would choose the aluminum foil.
a conductor attracts and an insulator keeps it all together
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.
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.
yes it is because it traps the coolness inside.
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
insulators
It actually isn't a good insulator. Tin foil and aluminum are good conductors, not insulators.
No, it is not an insulator.
Insulators are objects that prevent the transfer of heat, so some good insulators would be cotton balls, tin foil/aluminum foil, socks, rubber etc. Get what I mean ? :O Later days, dude or dudette whatever you are.....
Aluminum is a conductor and glass is an insulator. Conductors allow the flow of energy transfer, but insulators block this transfer of energy. So by definition, Yes, aluminum conducts cold or heat(energy) transfer faster than glass.

it is used as an insulator for temperature, electric, or magnetic charge. It is effective at all three.
No, they are at exactly the same temperature. But aluminum is a heat conductor and so removes heat from your finger/hand/etc. faster than does wood which is a heat insulator; so the aluminum feels colder than the wood.
No
True..Materials, such as copper or aluminum, that offer low resistance to the flow of electric charge are called conductors.
