Oil is less dense than water
While certainly true, and part of it, it isn't the whole story. If this were the case, there wouldn't be many of the solutions that we know and love each day (think of beer...ethanol has a density of about 0.8, water is 1...how can it be mixed?).
The main component for this is that there are significantly different forces holding the water molecules to other water molecules, and oil molecules to other oil molecules. Water is very polar (has ends with unequal electron distribution, a slight charge), and oil is non-polar: all the electrons are evenly spread-out. The water molecules are attracted to each other by this separated charge, the oil molecules are attracted to each other due to the lack of separated charge, but they are not attracted to each other. That's where the density comes into it!

Is oil liter than water?
well water weighs more becuz the oil happens to be light
If you pour some oil into a glass of water will it sink or float?
The oil will float on top of the water because it is less dense than water. Oil and water do not mix well due to their different densities and polarities, causing the oil to form a distinct layer on top of the water.
Is water denser than oil?
Yes, water is denser than oil. Water has a higher density because its molecules are tightly packed together, while oil molecules are more spread out and have lower density. This difference in density is why oil floats on top of water.
Oil floats on to of water because?
oil is less dense than water, so it floats on top of the water. This is due to the difference in molecular structure and weight of the two substances. Oil and water do not mix easily because they are immiscible, resulting in oil forming a separate layer on top of the water.
How does oil catch fire on water?
Oil can catch fire on water due to the high temperatures that burning oil can reach. When oil is spilled or leaked onto water, it can create a large surface area, allowing it to ignite more easily. The heat from the flames causes the oil to vaporize, creating a flammable layer on top of the water that can sustain a fire.
Why does vegatable oil sit flat on top of water?
vegatable oil sit flat on top of water because of density. Density of vegetable oil is more then water .Hence oil float
How does oil get into water?
Oil and water can't mix. They won't go together. The oil with just sit it the water or on top of the oil the water.
How does oil sit on top of water in an oil spill?
Oil is less dense than water, so it sits on top. It is also organic so is immiscible in water.
Why does oil sit on water?
oil has a least density than water so threfore it sits on top of it
When you mix thick vegetable oil and water together why does the vegetable oil sit on the top?
Vegetable oil is denser then water, so it floats on top. Oil is also a lipid, which is hydrophobic, meaning it does not like water. They do not mix.
How do you separate oil and water in a container?
they separete on their own if you let the container sit, the oil rises to the top
Oil floats on water because its density is what on water?
Type your answer here... the oil has more density
Why does vinegar sit on top of water and not mix in?
The vinegar sit on top of the water because the water is more dense than the vinegar
What are some ways of separating of a mixture?
Put two difference types of liquids that have different density's. Like put water and olive oil and the oil will sit on top of the olive oil.
What Does Iceland Sit On Top Of?
Iceland sits on top of water.
Does oil create a barrier on top of water?
oil is less dense then water so oil floats on top of water.
How we can separate oil from water?
Allow the mixture to sit until the oil and water have separated. Then pour off the oil.
