The aluminum foil is less dense than the water which makesit float. Aluminum foil is not less dense than water. It is more dense. The reason that aluminum foil floats is that the surface tension of the water will hold the sheet of foil. If you still think that the aluminum foil is less dense than water, try floating a roll of foil in a bucket.

∙ 10y agoThat depends upon the shape of the aluminum. For example, in the shape of a boat it will float. In the shape of a solid sphere, it will not float.
A thin sheet of alu foil may stay on the surface as long as there is no water sprayed on it nor immersed under water, then it will sink.

∙ 13y agoAluminum can float on water two different ways:
- It can rest on the surface without breaking the surface tension. Small bits of aluminum foil can be laid onto the surface of a cup of water and they will not sink immediately. If you have a steady hand, you can even float a steel needle on the surface of water. Lower it down with a fork.
- It is formed into a hollow shape. An aluminum can, full of air will float because the weight of water it displaces is greater than its weight. An aluminum boat will float for the same reason but it will sink once it fills with water.

- Th density of aluminum is 2.7 g/mL, which means the metal will sink in water, but is still relatively light. Chemical Properties: The surface of aluminum metal is covered with a thin layer of oxide that helps protect the metal from attack by air.

Wiki User
∙ 14y agobecause tin foil is less dense then water so it makes it float!!!!
Wiki User
∙ 13y agoAluminium is denser than water. So it should sink. But it depends on the shape of the aluminium. If it is flat it might float.
Wiki User
∙ 10y agoI'm assuming you mean why aluminum cans float in water. This is because
the density of the aluminum can is lower than the density of water.
Wiki User
∙ 11y agoIt floats because the boat and the air inside have a density lighter than the water's density.

What minerals are in aluminum foil?
No but it is made of aluminum which is the most prevalent element in the earth.
What keeps things colder plastic wrap or aluminum foil hypothesis?
aluminum foil
What elements are in aluminum foil?
Aluminum foil is not an element as the foil has a small amount of other stuff added to it to make it an alloy. Aluminum element would only have aluminum atoms and no other compounds added to it. An alloy has two or more metals together.
Is aluminum foil cut in half a physical or chemical change?
It is a physical change because it can be reversed. All you have to do is weld the foil back together!
What material keeps things colder plastic wrap or aluminum foil?
aluminum foil is better at blocking temperature from getting out than plastic wrap. the atoms in the element aluminum are bigger and have more neutrons/electrons and protons than the elements in plastic wrap.
How can aluminum foil float in water?
A thin aluminum foil can float on water if placed carefully flat on the surface because of the surface tension of water. If you were to submerge it, the foil will sink.
Can you make a piece of aluminum foil float in air?
yes
Why do boat made from aluminum foil float in xenon gas?
it floats because the xenon gas particles are heavier that the aluminum foil's.
How does aluminum foil boat float?
An aluminum foil boat floats because it is more dense than water, therefore the surface tension of the water is able to hold the boat up.
Is a aluminum foil a compound or elements?
Aluminum is element. Aluminum foil is made entirely of aluminum.
Is aluminum foil float on water?
A thin aluminum foil, (which is denser than water) could float on the surface if carefully placed, by virtue of the surface tension of water. But if submerged, the foil would sink due to its higher density. Generally speaking, a denser substance will sink in a less dense substance. Assuming standard temperatures, since aluminum has a density of about 2.7 grams per cubic centimeter and water only has 1 gram per cc, aluminum would sink. (An aluminum boat would float because it displaces a greater mass of water than its own weight.)
Is aluminum foil an element?
Aluminum foil is made of Aluminum, which is an element. So yes Aluminum foil is a element
Does aluminum sink or float in water and why?
Generally speaking, a denser substance will sink in a less dense substance. Assuming standard temperatures, since aluminum has a density of about 2.7 grams per cubic centimeter and water only has 1 gram per cc, aluminum would sink. A thin aluminum foil could float by virtue of the surface tension on water (but if submerged, will sink). An aluminum boat would float because it displaces a greater mass of water than its own weight. An aluminum block could also float on a liquid of higher density than the aluminum.
What elements is used in cookwear and cooking foil?
Tin foil... tin Aluminum foil... aluminum :)
Why do the pieces of aluminum foil have different masses?
Because all aluminum foil is not equal. Aluminum foil is available in a variety of thicknesses.
Why is aluminum a pure substance?
Only a single component makes up aluminum foil, which is the aluminum element. Hence, aluminum foil is considered as a pure substance.
Is aluminum foil iron?
Shut up....iron is an aluminum foil
