Can aluminium float in water

Answer 1

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.

Answer 2

Aluminum pellets will not float in water. Aluminum's density is 2.7 g/cm3. Water's density is 1.0 g/cm3. Since aluminum has a higher density (it is heavier) it will sink in water.

*** However, if the pellets are very small, the surface tension of the water will hold them, causing them to "float." :)

Answer 3

Aluminum can float in water if its density is less than the density of water, which is approximately 1 g/cm³. Aluminum has a density of about 2.7 g/cm³, so it will sink in water. However, thin sheets or foil of aluminum can sometimes appear to float due to surface tension.

Answer 4

Put aluminum film in the water and see it for yourself.

Yes, it will float as long as it has a big surface. It will not if it is a small piece.

Answer 5

Aluminum powder floats on water due to the surface tension of the water. However if you break that surface tension by adding detergent or soap to the water the aluminum powder sinks.
