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.)

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.
Why might a tightly crumpled ball of foil sink but a flat piece of foil of the same mass float in water?
A tightly crumpled ball of foil might sink in water because it's density is greater than water. When foil is flat it's density is less than water and it will float.
Can you make aluminum float in water?
yes
What happens to aluminum foil in salt water?
Electrolysis will start.
Is aluminum foil a mixture or compound?
it is an element
How can aluminum foil float in water?

Why does aluminum foil float?
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.
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.
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.
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.
How does a tin foil raft float?
A tin foil raft, which is just a flat piece of tin foil (which we know is really aluminum foil), floats by means of the surface tension of the water that supports it. We all know that aluminum is more dense than water. A block or other chunk of aluminum would sink in water. But because the aluminum foil is thin, its mass is "spread out" over a wide area, and this causes a broad interaction with the surface tension characteristic of water.

What keeps water colder aluminum foil or plastic wrap?
aluminum foil
What will you do with an aluminum sheet to make it float in water?
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.
Why does tin foil float?
because tin foil is less dense then water so it makes it float!!!!

How can I keep water cool?
cover it with an aluminum foil
