No, things can also float in gases like air or other fluids with different densities. The key factor is the buoyant force, which is the upward force exerted by a fluid on an object immersed in it, supporting the object's weight and allowing it to float.

Why does only light things float in salt water?

Whether things float or sink this depend only on the density , the density of the salt water is aprox. 1030 kilogram per meter cube so if you but things have density less than that they will float , things with higher density sink.


Does oil float on all liquids?

No. Depending on the purity, ethanol (the alcohol in booze) can float on kerosene, but only barely. For the most part, yes.


Can light things float on water?

If it has enough surface area such as a leaf or bigger yes so long as it lands on the water in such a way it traps a little air under it, note..even concrete can float, many septic tanks are made of concrete and will float in only about a foot of water if you dont remember to fill them with water before it rains


What causes thing to float in the ocean water?

Atoms like oxygen and hileum like a water bottle floating but only when it has oxygen in it. If you crushed the bottle it will have less oxygen making it not float but not all atoms make things float. Also your welcome if it helped.


Can water dissolve in anything?

Water can mix with other liquids that are polarand can form Hydrogen bonds. Its a bit involved to go into here but suffice to say that liquids only mix with other liquids that are like them. Liquids that can form hydrogen bonds will mix with water, oils or hydrocarbons cannot do so and do not mix with water, that's why oils float on top.Think of the BP oil spill, instead of mixing with the water the oil floated to the top. Look up water on wikipedia and they'll go into its properties to degree level probably.Also in terms of water dissolving solids it can again only dissolve things which it can hydrogen bond with which includes sugar and ionic crystals like table salt. This is a general answer some things will still not dissolve but that's way too complicated to talk about here. Hope this helped. =]


Is it true that a human can only float when there is salt in the water?

Yes if theres enough salt in the water you can float


Will an egg float in ice cold water?

Only an altered egg float.


Why can metal float?

For something to float, it must displace the same amount of water as it weighs. Answer:To float in water, a solid metal object must be lighter than the water equivalent to its volume. This would make lithium (at S.G. 0.53) the only metal that would float in water.Objects which are hollow and made of metal float because the contained volume of the object divided by the weight of the object is less than 1 gm/cm3, the density of water. Solid metal objects can float in liquids which have a density greater than they exhbit thesmelves. As an example, almost all metals will float in mercury

Well not all organs can float, but lungs can float on water


Do all frozen liquids float on their liquid as ice floats on water?

No. Exactly the opposite. Water is the only known substance whose solid form floats in its liquid form. Which, incidentally, is a lucky accident, since life on earth would be impossible if ice sank in water.
