Water is denser than oil because strong forces of hydrogen bonding are present in between the water molecules so that are very close to each other and thus water has high density. While on the other hand in oil long chains of hydrogen and carbon are present, oil is non polar so the chains of carbon and hydrogen are far apart and do not attract each other. Thus oil is less denser than water and floats on water.
The concept of density can be understood by the thing that one tonne of oil and one tonne of water has equal weight but one tone of oil occupies more space than one tonne of water as water molecules are present very close to one another or in other words water is more dense than oil.

∙ 11y agoBecause its particles aren't as close together weighing it down. Water particles (H2O) are closer together (making the substance more dense) because they "want" to hydrogen bond with each other, which is energetically favorable. Oil (or any hydrocarbon) mainly "want" to just not be pushed up to another molecule so are farther apart at normal temperatures. Under very cold conditions this is less so (water is peculiar in that when it freezes it actually becomes less dense, that's why ice floats).

∙ 13y agoYes, Water weighs more than Oil as Oil floats on water.

∙ 9y agoWater is not heavier then oil. Oil is less dense then water which is why it floats on top of water.

∙ 13y agooil is less dense than water and therefore floats. It is however more viscous (gloupy)

Why oil is more denser than juice?
Juice is much denser than oil. Juice will sink and some what combine with water while oil floats on top of water.
What Oil floats on water because it is denser true or false?
Oil floats on water because water is denser than oil.
Does water have greater density than oil?
No, water has more density than oil. If something denser than water(Eg=Iron) is dropped to water, it sinks, while less denser will float. Oil floats on water. Really I've tested it
Is chloroform denser than water and oil?
Yes It Is! because of its chlorine content.
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.
Why oil is more denser than juice?
Juice is much denser than oil. Juice will sink and some what combine with water while oil floats on top of water.
What Oil floats on water because it is denser true or false?
Oil floats on water because water is denser than oil.
Which is denser oil or water?
what i think is oil is denser because denser mean mass which is heavy and that is why the oil goes on the bottom when you add oil with water
Why does a small pebble sink in water?
because a pebble is denser than water thus making it sink oil is not denser than water.
Is mustard oil denser than water?
yes
Does oil float on fresh water?
yes , because oil is less denser than water
Does water have greater density than oil?
No, water has more density than oil. If something denser than water(Eg=Iron) is dropped to water, it sinks, while less denser will float. Oil floats on water. Really I've tested it
Is water denser than oil?
No, in general most oils are LESS dense than water.
Is vegetable oil denser than mouthwash?
Oil has a density of about 0.8 - 0.9. Mouthwash (which is naminly water) has a density of about 1. So no, mouthwash is denser.
Is chloroform denser than water and oil?
Yes It Is! because of its chlorine content.
Why would a small pebble sink and an oil tanker floats?
Because a pebble is denser than water thus making it sink oil is not denser than water. you can test this by pouring some oil in a glass of water it floats on top of the water it doesn't sink it is the same theory with the oil tanker in the sea.
Is cooking oil denser than water?
Olive oil is not denser than water. This can be verified by placing olive oil and water together and observing how olive oil stays on top of the water, proving itself to be lessdense.
