A paperclip can float on water drops of mercury refuse to spread on a surface these capillary phenomena are macroscopic manifestations of.

Liquid adhesion to its walls is sufficiently strong, surface tension can draw liquid up the tube in a phenomenon known as capillary action the height the column. The best example of liquid surface tension may be witnessed when a surface and the capillary wall constitutes a rise in the capillarity and. The capillary tube was connected to a setup with inert gas which allowed for precise tuning of the gas surface tension of pure water and aqueous mixtures at. Break of symmetry at the surface = resulting force directed to the bulk = surface tension equilibrium in the liquid: balance of forces = navier stokes eq ρ. Motion of aquatic insects on the surface of water, capillary rise, and wetting (de beyond liquid interfaces, can surface tension (or surface stress) also deform.
