What role does cohesion and adhesion play in surface tension?

Cohesion holds hydrogen bonds together to create surface tension on water. Since water is attracted to other molecules, adhesive forces pull the water toward other molecules.

How do the particles in a liquid create surface tension?

The surface tension of a liquid results from an imbalance of intermolecular attractive forces, the cohesive forces between molecules: A molecule in the bulk liquid experiences cohesive forces with other molecules in all directions. A molecule at the surface of a liquid experiences only net inward cohesive forces.

Which substances do you think will experience the greatest adhesive force?

A hydrogen bond (H-bond) is an example of an intermolecular force(IMF). IMFs occur between all molecules, but hydrogen bonds are the strongest.

Do other liquids have surface tension?

Because of the relatively high attraction of water molecules to each other through a web of hydrogen bonds, water has a higher surface tension (72.8 millinewtons (mN) per meter at 20 °C) than most other liquids….Contact angles.

Does Pentanol have more surface tension than pentane?

Students see that even though the only difference between pentanol and pentane is an -OH group, pentanol has basically the same surface tension has decane; a molecule that has a noticeably greater surface tension than pentane.

Why does glycerin have a high surface tension?

This high surface tension is due to the strong association between molecules of glycerol [6]. Firstly, the surface tension of glycerol is higher than most of the organic liquids [6]. This high surface tension is due to the strong association between molecules of glycerol [6] .
