Surface Tension


Definition
Surface Tension is a measure of the enhanced intermolecular forces at the surface of a liquid
 
Key Context
Liquid molecules contain intermolecular forces that hold the fluid together. These cohesive forces exist between each molecule and its neighboring molecules. A surface molecule does not have neighboring molecules above the surface, so it exhibits greater intermolecular forces with its remaining neighbors.

Greek/Latin Etymology
Latin root tension meaning “to stretch.”
