Because 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).
Oil is less dense than water. That is why oil floats on water.
Oil is less dense than water, but it is more viscous (has more resistance to flow). Perhaps that's what you were getting at.
Correct!Therefore oil floats on water.
because water can float that all I Know
claim
Kerosene and turpentine are less dense than engine oil. So is water and rubbing alcohol and other common liquids.
Oil and water do not mix. Since ice is made of frozen water, it floats on oil because it will not mix with it and also because ice is relatively light
more dense substances sink, less dense substances float. oil will not sink in water, it will float, it is less dense.
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

Oil IS already less dense than water.
No, in general most oils are LESS dense than water.
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.
The density of water is greater than that of oil.
oil
Oil is less dense than water.
No, it is more dense than water and cooking oil.
Kerosene and turpentine are less dense than engine oil. So is water and rubbing alcohol and other common liquids.
oil
Because oil is less dense than water.
Yes, syrup is more dense than water because of the sugar and oil is less dense than water, like all other oil.
No. Oil floats on water because it is less dense than water.
