Why does water float on oil?
The oils have low density as compared to water and oils are non polar organic compounds while water is a polar compound, so oil can not mix with water and floats on waters surface.
Why mosquito float on the surface of water?
Due to the property of surface tension water surface would act as a stretched membrane. So water skaters, mosquitoes could easily walk on the surface. If oil is mixed with water then surface tension would fall and mosquito cannot breed. That is why we sprinkle oil in fine droplets on stagnant water
How does a needle float on water?
the way it float is surface tension!!
What kind of objects float above water?
Any item that is lighter than the water will float on the surface of the water.
What makes a needle to float in water?
Water surface tension hold the needle on the water surface.
Is USP mineral oil soluble in water?
No, it is not. Oil and water do not mix. If you pour oil into water, the oil will float to the surface. If you pour water into oil, the water will sink to the bottom and the oil will float on top.
How do you separate water from synthetic oil?

What liquid does gold float on?
Gold can float on water if there's a layer of oil on the surface. To break the surface tension, a drop of Dawn soap will do the trick.
Does cooking oil have more surface tension than water?
Because of the polarity of the water molecule, hydrogen bonds form between them. This results in the higher surface tension. Oil is nonpolar, so hydrogen bonds do not form between the molecules, so the surface tension is less.
How can we separate soap and oil from water using a decanter?
Oil float over the water surface; use a decantation funnel for separation.
Why does water float on oil?

How oil spills act as water pollutant?
Oil will float to the surface of the water.So,any living things in the water cannot get any oxygen and they will die .

Do oil sink or float in water?
Float.
What type of water is most likely to float on the surface of the ocean?
Ice is a form of water that will float on the surface of the ocean.
Will crude oil float on water or sink?
Most (but not all) oil is less dense than water. That oil which is less dense than water will float. That oil which is denser than water will sink.
How does a needle float on water?
