Does water float

Answer 1

Ice (solid water) floats on liquid water.

Fresh water floats on salt water (less salty floats on more salty).

Warm water floats on cold water.

I was in a fjord in northern Norway some summers ago and the glacial runoff (fresh water) floated on the sea water of the fjord. A layer about 3 centimeters thick on top of the water in the inner part of the fjord was not salty at all ( I tasted it). When you stirred you could see the differences in optical density too. This also caused trouble for boats as hydrodynamic drag increases noticeably when there is a layer of fresh water on top of the salty water.

Answer 2

The obvious correct answer is ice floating on liquid water.

It is also possible to float pure water on top of salt-water - which sort of qualifies as "floating water on water". You can observe the phenomena by first dissolving a lot of salt into some water and then adding a bit of food coloring to dye it. Next take some regular tap water and add a bit food coloring of a different color. CAREFULLY pour the tap water on top of the salt water avoiding mixing the two as much as possible and you will see two distinct layers at 2 different colors. It will persist for some time while the dyes gradually diffuse into the different layers and as the salt in the salt water gradually diffuses into the upper layer. The pure water - which is less dense - will "float" on the salt-water - which is more dense.

It is actually possible to do a similar trick with hot and cold water but it's much more difficult to keep them from mixing. The cold water will be a little more dense than hot water so you would put that in first and then add the hot water. Until thermal equilibrium is established, the hot water essentially "floats" on the cold water.

Answer 3

sometimes . . . Its the only liquad in its solid form to float on its liquad form. This is because water forms hydrogen bonds, which form large spaces of air, creating the ice to be less dense then liquad water. this is just a joke don't write this I'm just messing with you

Answer 4

Water does not float on more water. Water combines into ... water.

Answer 5

Yes. Ice, which is solid water, will float on top of liquid water.

Answer 6

no, it would mix with itself

Answer 7

Yes.

It's call undercurrent

Answer 8

It depends what liquid it is.
