Surface Tension of Common Esters
Surface tension refers to the tendency of the surface of a liquid to minimize its surface area. The surface tension of esters is influenced by the molecular structure of the specific ester in question.
The following table provides a curated list of surface tension values for different esters under 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
