Surface Tension of Common Alcohols
Surface tension is a property of liquids that arises due to the cohesive forces between molecules at the surface of the liquid. The following table provides a curated list of surface tension values for common alcohols at 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
