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.
The âstickyâ property of water is called cohesion. The cohesion between water molecules is so strong that when they come in contact with another substance, such as air, the water molecules at the surface create a sticky skin.â This is known as surface tension. Water has a high surface tension. These bonds are so strong that they can support the weight of insects such as water striders.
