Surface Tension Surface tension is the skin-like surface of a liquid due to the cohesive forces between the liquid molecules. The diagram below shows an imagined magnified view of the surface of water, the molecules of liquid at the surface do not have other like- molecules above them.
What are some of the primary conditions that affect surface tension? The surface tension. characteristics of a fluidic substance stay basically stable, but can be changed by temperature variations, chemicals that modify the bonding characteristics of the molecules, oxidation and the presence of impurities.
