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 the elastic tendency of a fluid surface which makes it acquire the least surface area possible. Surface tension allows insects, usually denser than water, to float and stride on a water surface. At liquidâair interfaces, surface tension results from the greater attraction of liquid molecules to each other than to the molecules in the air. The net effect is an inward force at its surface that causes the liquid to behave as if its surface were covered with a stretched ...
