Which will float and which will sink a piece of Styrofoam a piece of oak and a gold ring?
The piece of Styrofoam will float, the piece of oak will sink, and the gold ring will also sink. Styrofoam is less dense than water so it floats, while oak and gold are denser than water so they will sink.
Does mass alone determine wheter an object will float or sink?
No. The key to whether an object floats or sinks is the average density, i.e., mass divided by volume. Also, whether an object will float or not also strictly depends on the surface volume. A piece of tin foil shaped into a boat will float and the same mass of tin foil shaped into a crumpled up ball will not float.
Does the piece of lungs tissue float or sink in water?
Lung tissue is denser than water and will sink when placed in it.
Will a tooth brush sink or float?
This depends on the density: if the density is greater than 1 g/cm3 (density of water) an object sink; if the density is lower the object float.I tested just now four tooth brushes: three sink, one float !
Will a piece of iron float in water?
No, a piece of iron will sink in water because its density is greater than that of water.
Why might a tightly crumpled ball of foil sink but a flat piece of foil of the same mass float in water?
The tightly crumpled ball of foil has a smaller volume with less air trapped inside, making it denser and likely to sink. The flat piece of foil has a larger surface area and traps more air, increasing its buoyancy and allowing it to float despite being the same mass as the crumpled ball.
What is the reason that a crushed tin ball of foil will sink and and flat piece of it floats?
A flat piece of tin foil may float on top of water due to surface tension. A crushed ball of foil does not have near the amount of surface area in contact with the surface of the water, so the surface tension is not sufficient to keep it suspended. Note that if you place a flat sheet of foil in the bottom of a container and pour water in on top of it however, it will not rise to the top to float; you have to place it on top carefully in order to get it to float.

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.

Does copper wire sink or float?
A short piece may be supported by the surface tension of water, but a coil of copper wire would sink.
Do clothes float or sink?
it will float as long as it is not fully covered 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.
Is aluminum foil float on water?
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.)
