I believe all liquids have intermolecular forces of attraction between the molecules, whether they are small forces such as dispersion forces or stronger ones like hydrogen bonding in water etc.
When in, "Bulk" such as in the middle of a liquid (not the surface) these forces are experienced all around the molecule in equal amounts and therefore no net force is experienced. However, at the surface of the liquid there are no attraction forces from above and so the molecules experience a net downwards pull.
This causes the molecules at the surface to be pulled into the liquid, compressing the space at the surface. This smaller, denser and more packed surface is what causes the surface tension...correct me if I'm wrong. :)
What else can I help you with?
What substance has the largest surface tension at room temperature?
Water has the highest surface tension of common liquids at room temperature. This is due to its strong hydrogen bonding, which creates cohesive forces between water molecules that pull them together and give water its high surface tension.
What do cohesion surface tension and adhesion have in common?
Cohesion, surface tension, and adhesion are all properties related to the interaction of molecules in liquids. Cohesion is the attraction between molecules of the same substance, surface tension is the result of cohesive forces at the surface of a liquid, and adhesion is the attraction between molecules of different substances. These properties all involve the forces that hold molecules together in a liquid.
What common liquids have a pH level of 5-6?
Common liquids with a pH level of 5-6 include black coffee, orange juice, and tomato juice. These liquids are slightly acidic but are safe to consume in moderation.
What liquid does gold float on?
Gold can float on water if there's a layer of oil on the surface. To break the surface tension, a drop of Dawn soap will do the trick.
Which phase of matter is the least common on earth?
Plasma is the least common phase of matter on Earth. It requires very high temperatures to exist, so naturally occurring plasmas on Earth are relatively rare compared to solids, liquids, and gases. Examples of plasma on Earth include lightning, the sun's atmosphere, and some types of flames.

Which liquid has the lowest surface tension?
if you are doing a science project......you might wanna try diffrent liquids on the effect of (surface tension).... milk water juice paperclip water is best for the atraction of ST. milk and the juice is what reduces ST the best The body contains a natural surface tension reducing substance called surfactant.It is found in the lungs and prevents the lungs from collapsing due to surface tension when you exhale
A consequence of the surface tension of water is what?
capillary action is a common consequence of surface tension.
What do cohesion surface tension and adhesion have in common?

What do cohesion and surface tension have in common with reference to water?
Between water molecules a big cohesion force exist; this is the cause of the high surface tension of water.

How do you measure surface tension and what methods are commonly used for this measurement?
Surface tension is measured by determining the force required to break the surface of a liquid. Common methods for measuring surface tension include the drop weight method, the capillary rise method, and the maximum bubble pressure method.
What are wetting liquids in thermometer?
Wetting liquids in thermometers refer to liquids that adhere to the surface of the capillary tube, allowing for a more accurate and consistent measurement of temperature. Common examples include mercury and certain organic liquids like toluene or alcohol. These liquids expand uniformly with temperature changes, providing clear readings. However, mercury thermometers are being phased out due to environmental concerns, leading to increased use of alternative wetting liquids.
What is the substance that keeps the liquid apart in an emulsion?
An emulsifier is the substance that keeps the liquid components in an emulsion from separating. Emulsifiers work by lowering the surface tension between the two liquids, allowing them to mix and remain stable. Common emulsifiers include lecithin, egg yolks, and certain proteins.
What do cohesion surface tension and adhesion all have in common with reference to water?
Cohesion, surface tension, and adhesion are all properties of water that stem from its ability to form hydrogen bonds between water molecules. Cohesion refers to water molecules sticking to each other, surface tension is the result of the cohesive forces at the surface of water, and adhesion is the attraction of water molecules to other substances.
What are the examples of surfactants?
Common examples of surfactants include sodium lauryl sulfate (SLS), cetyltrimethylammonium bromide (CTAB), polysorbate 80, and octylphenol ethoxylate. These chemicals are used in various products such as shampoos, soaps, detergents, and cosmetics to reduce surface tension and improve the wetting and spreading properties of liquids.
Is bar soap is common solvent?
No, bar soap is not considered a common solvent. Solvents are typically liquids that dissolve other substances, while bar soap is a solid surfactant used for cleaning. It works by reducing the surface tension of water and helping to emulsify oils and dirt, allowing them to be washed away, but it does not dissolve substances in the way that traditional solvents do.
