it is used as an insulator for temperature, electric, or magnetic charge. It is effective at all three.
No but it is made of aluminum which is the most prevalent element in the earth.
Yes, you can buy both sandwich bags and aluminum foil at most grocery or department stores.
Plastic!!!!!!!!!! Aluminum recycles, but most plastics do not.
Aluminum foil traps the most heat among aluminum foil, plastic wrap, and wax paper. This is because aluminum foil is a better conductor of heat compared to plastic wrap and wax paper. When food is wrapped in aluminum foil, it reflects and retains heat more effectively, keeping the food warmer for longer periods.
Aluminum foil is made of aluminum, so it is essentially 100% aluminum. There may be trace amounts of other elements used in the manufacturing process, but the material itself is predominantly aluminum.
aluminum foil is going to be the worst insulater, paper is a good insulater but not the best, so the best is cotton.
depends on foil:aluminumgold (usually called leaf not foil, most common use is lettering on leather bound books)silver (usually called leaf not foil, most common use is lettering on leather bound books)tin (used for purpose aluminum foil is used for, rarely seen today)lead (often used in roofing to prevent leaks from pooling water, thick for foil)etc.
Aluminium foil is recyclable; in fact, it's one of the most lucrative items you can recycle. Aluminum is difficult to extract, so recycling it is important for those that produce aluminum products as well as the consumer.
Most foil is made from aluminum. Elemental aluminum is highly reactive but this means it reacts with oxygen in the air before you get to using it on your food. Therefore the foil has an outer layer of aluminum oxide which is quite unreactive. This doesnt undergo reactions with food.
No. Aluminum will degrade faster than most metals, especially if it is left in salt water, such as at the bottom of the ocean. This is true. Aluminum foil is not biodegradable. your welcome, : )
Tin foil is typically made from aluminum, which is a widely available and commonly used material. Aluminum is extracted from bauxite ore through a process called electrolysis, and it is then rolled into thin sheets to create foil. Most aluminum foil production is concentrated in countries like China, the United States, and Germany.
Most mirrors are made of glass with an aluminum foil behind them.
