True or False: Liquid oxygen should have a larger surface tension than liquid bromine (assuming T and P are the same for both liquids). False: Surface tension of liquids increase as Intermolecular Force strength increases. Both O2 and Br2 are non-polar molecules, and have only dispersion forces. Those dispersion forces are stronger for Br2, however, since it has many more electrons (70 vs. 16) than does O2.
Surface tension is an effect where the surface of a liquid is strong. The surface can hold up a weight, and the surface of a water droplet holds the droplet together, in a ball shape.Some small things can float on a surface because of surface tension, even though they normally couldn't float.urface tension has the dimension of force per unit length, or of energy per unit area. The two are equivalentâbut when referring to energy per unit of area, people use the term surface energy âwhich is a more general term in the sense that it applies also to solids and not just liquids.
