oil is denser than water, it breaks the surface tension because it is another liquid with a higher density. we dont break the surface tension because we are a solid. the oil is a liquid... look at a lava lampp for example, it has oil and water but the oil is constantly moving upward because it has a hgiher density- the heat causes it to rise and the density causes it to sink. so oil with slip right through water destroying the surface tension
Oil is NOT denser than water. Oil is less dense than water which is why oil floats on water. This makes your answer completely incorrect.

Does oil break surface tension in 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.
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.
Does vegetable oil have more surface tension than water?
No. Vegetable oil's surface tension is approximately 34 dynes/cm while ultrafiltrated water is 72.40 dynes/cm.
Why does water have higher surface tension than oil?
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 you test how much weight the surface tension of water can hold?
Small insects such can walk on water because their weight is not enough to penetrate the surface. A carefully placed small needle can be made to float on the surface of water even though it is several times as dense as water. If the surface is agitated to break up the surface tension, needle will quickly sink.
How are small insects able to walk on the surface of water?
The oil on their feet is strong enough to repel the water and there weight is spread out enough that when their feet touch the water, the oil and the water repel each other like when you pour oil on water the oil floats on the top... same principle
Why does a drop of water placed on the surface of oil contracts to form a spherical shape?
The surface tension of the water and the fact that oil and water cannot wet each other.
What is the scientific explanation behind the oil on water effect?
The oil on water effect is due to differences in density and surface tension between oil and water. Oil is less dense than water and does not mix with it because of its hydrophobic nature. When oil is poured onto water, it forms a thin layer on the surface due to its lower density. The surface tension of water also plays a role in keeping the oil molecules together and preventing them from mixing with the water molecules.
How does soap effects the surface tension if water?
the surface tension has bonds, and the soap breaks those bonds, so if the soap water is put onto a surface.. it will slip off
How doe soap make it possible for water and oil to mix?
The chemical properties in soap break apart the surface tension of water which doesn't allow water and oil to mix. When you add the soap, the two liquids mix homogeneously.
Why does oil move away from water?
Oil and water are not co-soluble, or "miscible." Because they don't mix, the difference in surface tension causes oil and water to pool separately.
