Why do non polar molecules usually have a much lower surface tension than polar ones?

because they form London Dispersion bond which is the weakest among the inner-molecular bonds

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.
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.
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 do you slow down molecules?
You decrease the temperature. Temperature is the measurement of the average speed of the molecules in a substance. The faster the molecules are moving, the higher the temperature. The slower, the lower the temperature.
How soaps lower the surface tension of fat an oil?
Actually, the soaps lower the surface tension of water, allowing fats and oils to be washed away. Soaps are a long molecule with a polar end, which is hydrophilic, and a non-polar end, which is hydrophobic. Water is polar, so the hydrophilic end faces the water. Fats and oils are non-polar, so the hydrophobic end faces them. Water surrounds the fats and oils and is able to wash them away.
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.
What is the effect of detergent on the surface tension?
Detergent has the effect of reducing the size of the water molecules thereby reducing the surface tension of the water. This allows for the small water molecules to integrate themselves farther into fabric to remove contaminants.
Why did heating the water affect the surface tension?
Surface tension is lower at higher temperatures.
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 surface tension is a unique characteristic of liquid?
BEcause as the name suggest,first of all it is a tension or like a pull.Molecules of water are freely movable comparatively to solid. So at the surface there is jiggling of molecules ,some goig to atmosphere and some are being pulled back by lower molecules who want to come at surface.
Does gasoline have a low surface tension?
yes it is lower than the surface tension of water
Surface tension of water on adding detergent?
Well If you have a pie pan filled with milk and then drop 4 diffrent colors of food coloring droped in but not touching then get a tooth pick with detergent on it and touch it in the foodcoloring will swirl out like tie die in the pan.
What are compounds that lower the surface tension of water?
Unit cells
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 concentration affect surface tension?
As the strength of intermolecular forces(IMFs) increases, vapor pressure decreases. This is because when IMFs are stronger it is harder for the compound to go to the gas phase, this means that the pressure the compound is exerting on the surrounding environment is lower.
What causes detergent to lower the surface tension of water?
Some mood music.
Why do organic liquids have lower surface tension than water?
water has hydrogen bonding. this is between the OH and the H of another molecule. this is a strong bond that organic molecules other than alcohols don't have.
