Oil is not as dense as water. So, even when they are mixed, the water molecules can still slide down in between the oil molecules, thereby causing the oil molecules to form a layer on the surface of the water.

What happens if oil and water are mixed together without an emulsifier?
Water is denser than oil because particles in the oil are more separated between each other than in water. This results in oil rising to the top, while water stays at the bottom of the recipient.
What rises when oil and water are mixed together?
The oil will rise to the top and float on the water.
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.
If you pour oil into a cup of water will the oil poison the water?
No. The oil should drain off of the water. Water and oil don't mix, so there would be no contamination. If there is something else mixed with the oil, though, it can possibly mix with the water.
What are examples of a homogenuous mixture?
Any mixture that looks the same throughout such as salt water (mixed well). Things such as oil mixed with water would not be because the non-polar oil will not disolve in the polar water or vice versa.
What happens if oil and water are mixed together without an emulsifier?
Water is denser than oil because particles in the oil are more separated between each other than in water. This results in oil rising to the top, while water stays at the bottom of the recipient.
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
Why only mono-molecular layer of oil formed on water?
This is because the oil and water want to interact as little with eachother as possible since the waters intramolecular forces are much stronger than an oil's. By forming a mono layer the surface area of the oil and water molecules are minimized as opposed to being mixed and having much higher surface area contact.
Why does water go straight to bottom when mixed with oil?
Water is heavier than oil. Oil floats on water.
What rises when oil and water are mixed together?
The oil will rise to the top and float on the water.
Why does a drop of oil placed on the surface of water spread over the entire surface?
because the water has more density than the oil so the oil spreads only on the surface.
What will happen if oil mixed with warm water?
Not a lot, water and oil don't mix and so the oil will float on top of the water.
When water and oil are mixed and they separate which one separates to the top?
oil
Why does oil in a bowl of water get repelled when washing liquid is dropped on it?
The oil is not repelled. It is floating on the surface of the water as a thin film. Water has very high surface tension, but when soap or detergent is added to water that surface tension suddenly drops. The water surface now contracts like a punctured rubber sheet toward the remaining area of high surface tension, dragging the oil film floating on its surface with it.
How can you tell if head gasket is blown?
Water mixed with oil? Oil mixed with water? White smoke out of tailpipe? Lack of compression on 2 adjacient cylinders?
If oil is mixed with boiler feed water?
Oils and water are not miscible.
Why does the oil remain on the surface of the water in the puddle?
the oil is denser
