Aluminum has a density of 2.7g/cc which is higher than that of water (1.0g/cc) and ordinarily would sink; if the can was empty and thus (like a boat) able to displace more weight in water (by virtue of its volume) than its own weight, it could then float. However, if it was filled with water, its overall density considering both the metal and the container's content, would be higher than water, and it would sink.
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.
Because the overall density of a can is less than the density of water, a solid aluminium pole has a density greater than water
You can conserve energy by building a solar energy unit using aluminum cans.
Depends on the medium, and whether the ball is solid or not. A solid ball would float on mercury, sink in water. If it were hollow enough (or filled with, say, cork) it would float in water.
Industrially it's quite simple - steel cans are magnetic while aluminum cans aren't.
No, aluminum soda cans will sink in water because aluminum is denser than water. The air trapped inside a closed soda can may cause it to briefly float, but it will eventually sink.
figure it out you stupid
Empty ones do. Full ones don't.
Aluminum powder will sink in water because it is denser than water.
Depends on what they're dropped into. Water - no. But drop them into something that's denser than aluminium and they will float.
Shape the aluminum to look like a boat, so it displaces enough water to float. The force supporting the aluminum is the buoyant force. It is equal to the weight of the volume of water displaced.

More aluminum cans!!!
Yes
No aluminum cans are not compounds. Aluminum cans are made of aluminum which is an element and is very metallic.

A solid bar of aluminum would not float, since its density (almost 3 grams per cc) is greater than that of water (1 gram per cubic centimeter). For an object to float in water, its density would have to be less than 1.0.
