Why does aluminum foil float?

Answer 1

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.

Answer 2

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.

Answer 3

Aluminum can float on water two different ways:

1. 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.
2. 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.

Answer 4

1. 2.7 g/mL
2. 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.

Answer 5

Normally, no but it can be made into a boat shape which will float

Answer 6

because tin foil is less dense then water so it makes it float!!!!

Answer 7

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.

Answer 8

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.

Answer 9

It floats because the boat and the air inside have a density lighter than the water's density.
