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.
Does kerosene float on water-?
no, beacuse there is more sugars patick present in it so it floats
Which has more surface tension clean water or soapy water?
Yes, pure water is a one molecule based structure, which hold together better than a mixture. When soap or other chemical is added, it breaks surface tension by getting in the way of each water molecule. Try putting water drops on a penny to build a bubble, then add a small drop of soap to it, you'll see that when soap is added, the water bubble collapses.
Why can a spoon hold more water than the level of its rim?
water does not lie entirely flat, the surface is convexed, causing a similar effect as a magnifying glass.
Explain how a paper clip can float in water?
Fill your container with water. Take a tissue, and rip it until you have maybe the size of half a dollar bill. Place the paper clip on the floating tissue. Poke the tissue with a pencil (not the paper clip), and when the tissue floats to the bottom, the paper clip will still be there.
Which will evaporate first-water or kerosen?
Kerosene will evaporate before water, given equal volumes and similar environmental conditions. The reason: water has considerable surface tension, brought about by hydrogen bonding between its very polar molecules. Kerosene is a hydrocarbon, and is non-polar, which means its molecules do not have a positive or a negative end. Water's surface tension resists evaporation. Kerosene's lack of surface tension (because of its non-polarity) makes it evaporate more quickly.
Is there anything such as water tension?
Yes. It is more specifically called water surface tension and it is the result of water's ability to form hydrogen bonds.
Do you think Salt water will have more or less surface tension than plain tap water?
more
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.
What are the application of surface tension in life?
They use it to take out harmful substances in a drug.
Why does acetone have a lower surface tension than water?
water is more polar than acetone
What does the term interfacial tension mean?
The term interfacial tension or surface tension means the contractive tendency of a liquid that lets it resist and external force. Interfacial tension could be observed from the floating of objects on the surface of water, even though they are more dense than water.
Do liquids that have higher tension produce drops that are flatter or more nearly sperical ttan liquids with lowersurface tension?
Surface tension causes molecules to hold to themselves more tightly. Therefore high surface tension liquids, like pure water, will form a taller drop and low surface tension substances, like oil, will spread out and be flat.
Does kerosene float on water-?
no, beacuse there is more sugars patick present in it so it floats
Does cooking oil have more surface tension than water?

Does fresh water have more surface tension than salt water?
Cold water has stronger (better) surface tension.Surface tension is dependent on temperature. For that reason, when a value is given for the surface tension of an interface, temperature must be explicitly stated. The general trend is that surface tension decreases with the increase of temperature, reaching a value of 0 at the critical temperature.From: http://en.wikipedia.org/wiki/Surface_tensionAdded emphasis for readability.dfsfdytrhjtkjkjh
How does bubble form?
Can you blow a bubble with pure water? NO WAY... because the surface tension of the water does not allow you to do so.Can you blow a bubble with soap-water solution? YES...Soap molecules contain hydrophobic chains that do not wish to stay in water. so they squeeze out to the surface of water and increases the gap between the water molecules on the surface, there by decreasing the surface tension of the water. With surface tension decreased you can blow a bubble.Here you can ask one more question...Why are Bubbles always spherical and not cuboid or some other shape?
