If you put water into water, it would eventually get mixed.
Fresh water is less dense than salt water and fresh water from rain or rivers will "float" on underlying salt sea water.
Water of different temperature and different salinity have different densities and do make layers in the oceans and lakes of the world.
Ordinary water will usually mix rather than separate, unless it is frozen into ice, which is less dense than liquid water.
There is also "heavy water" that has deuterium in the place of ordinary hydrogen and is ABOUT 11% denser than ordinary water, which will float above it.

∙ 10y agobecause density, d=0.890 - K and d=1.000 - Water, so potassium floats, but alkali metals react with water to produce hydrogen gas and heat, the reaction is exothermic which can vaporize some water.
calsium density d= 1.54
metal calcium (which is denser than water) reacts with water, alkaline aqueous calcium hydroxide is formed

∙ 7y agoPotassium floats on water, since potassium's density of 0.890g/cm^3 is less than water's density of 1.000g/cm^3

∙ 11y agoFluorine is a gas, so it will neither sink nor float, it will expand to fill whatever container it's in. If bubbled through water, it will quickly rise to the surface then dissipate.

What does 'like oil on water' mean?
water sinks in water, or rather, oil floats on water, and does not mix
How can you determine whether a soild object is more dense or less dense than water?
You can put a uniform object into water.If it sinks density is higher than water,if floats lesser than water.If you can place anywhere in water,density is equal to water.
Which is strong electrolyte potassium chloride or calcium chloride?
Both potassium chloride and calcium chloride are strong electrolytes when dissolved in water or when molten.
What does neutrally buoyant mean?
Something that neither floats nor sinks, stay in the middle of the tank or water subject it's in. Exp: bamboo with a balloon neither floats nor sinks in the tank. It stays in the middle on the 4 gallon tank.
How call you tell if a substance is more or less dense then water?
if it sinks its more dense if it floats its less dense
What sinks in water sinks to the bottom then floats again?
Not Yassine JR
Soap or styrofoam which one floats?
Styrofoam floats on water, Soap sinks.
Why iron nail floats on mercury but sinks on water.?
Iron has a higher density than water, so it sinks in water; but is less dense than mercury so it floats.
How does the density of each material relate to how high it floats in the water?
if its heavier than water it sinks. lighter floats
A solid that floats on water but sinks in methylated spirits?
Ice.
How does a submarine works that floats then sinks and then again floats?
A submarine sinks as it fills its' ballast tanks with water. Then it uses pressurized air to empty them and float again.
What floats in a bucket of water for 1 minute and then sinks to the bottom?
seamen
What does 'like oil on water' mean?
water sinks in water, or rather, oil floats on water, and does not mix
Why wood floats on water?
the density of water is higher than the density of wood... & so an iron piece sinks & a ton of wood floats...
How do you estimate the density of a liquid?
You can put it in a glass with water and see if it floats or sinks

What density table material floats on water but sinks on oil?
pine wood?
