Surface tension is the cohesive force at the surface of a liquid that makes it behave as an elastic sheet. It results from the greater attraction of liquid molecules to each other than to the molecules in the air.
5 Must Know Facts For Your Next Test
Surface tension is measured in force per unit length (N/m).
It is caused by cohesive forces between liquid molecules.
Surface tension allows small objects, even those denser than water, to float on its surface without sinking.
Temperature affects surface tension; higher temperatures generally decrease it.
Surfactants can reduce surface tension by disrupting molecular interactions at the surface.
