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.
That 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.
Aluminum can float on water two different ways:
Normally, no but it can be made into a boat shape which will float
because tin foil is less dense then water so it makes it float!!!!
Aluminium is denser than water. So it should sink. But it depends on the shape of the aluminium. If it is flat it might float.
I'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.
It floats because the boat and the air inside have a density lighter than the water's density.
No but it is made of aluminum which is the most prevalent element in the earth.
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.
It is a physical change because it can be reversed. All you have to do is weld the foil back together!
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.
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.
yes
it floats because the xenon gas particles are heavier that the aluminum foil's.
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.
Aluminum is element. Aluminum foil is made entirely of aluminum.
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.)

Tin foil... tin Aluminum foil... aluminum :)
Because all aluminum foil is not equal. Aluminum foil is available in a variety of thicknesses.
Only a single component makes up aluminum foil, which is the aluminum element. Hence, aluminum foil is considered as a pure substance.
it is an element
