Why is surface tension of water higher than surface tension of methane?
Wiki User

Hydrogen bonding. Water is a polar molecule so it is slightly negatively and positively charged on different ends and this leads to cohesion of the molecules; one to another. Alcohol is nonpolar.

∙ 11y agoBecause water molecules are more polar and smaller than alcohol molecules, they
are held more tightly and closer together than alcohol molecules giving water the
stronger surface tension.
Wiki User
∙ 13y agoWater molecules form strong attractions to other water molecules due to the two hydrogen bonds. Methane however is reliant on Van der Waals interations which are much weaker. Therefore water has a higher surface tension.

∙ 13y agoYes. I just did this lab in Chemistry. You can fit a less amount of drops of water on a penny when there is alcohol on it, than when there is no alcohol, because without alcohol, water has a greater surface tension than with alcohol.

∙ 11y agono, rubbing alcohol has more molecule weight, but since it does not have asm any hydrogen bonds like water, it would evaporate faster

What is the effect of pH on surface tension?
For most liquids, an increase in pH results in decreased surface tension. This has been attributed to lower attraction force between molecules when pH rises.
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.
What is a force that acts on particles at a liquids surface?
Surface tension. It always tends to acquire minimum surface area thats why water droplets form spherical shape.
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
Why does soap reduce the surface tension of water?
Soap will lower the surface tension of water. Like any surfactant soap will lower the surface energy by disrupting the strong inter-molecular hydrogen bonding that confers such a strong surface tension to water.
Does water have the highest surface tension?
No, mercury has a higher surface tension.
How does surface tension of water compare with the surface tension of most other liquid?
The surface tension of water is higher than that of most other liquids. Water has a surface tension of 7.29 * 10-2 J/m2 at 20oC.
Does water have a relatively high or low surface tension?
MERCURY has a higher surface tension than water. This highest surface tension between liquids is 487 mN/m at 15 0C.
How does the surface tension of water compare with the tensions of most other liquids?
The surface tension of water is higher than that of most other liquids. Water has a surface tension of 7.29 * 10-2 J/m2 at 20oC.
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.
What is the effect of pH on surface tension?
For most liquids, an increase in pH results in decreased surface tension. This has been attributed to lower attraction force between molecules when pH rises.
Why did heating the water affect the surface tension?
Surface tension is lower at higher temperatures.
What is the effect of sodium chloride on the surface tension of water?
The surface tension of water is increased for salted water.Sodium chloride increase the surface tension of water.
What properties of water is much higher than predicted?
Surface tension, boiling point.
Do small molecules have high surface tension?
Generally larger molecules with stronger intermolecular forces have higher surface tension. This tendency can be seen if you look at the surface tensions of the alkanes. Water is a clear exeption to this pattern due to the very strong hydrogen bonds.
What makes a needle to float in water?
Water surface tension hold the needle on the water surface.
What property of water let's bugs walk on water?
surface tension
