Webster's Unabridged Dictionary: Library in Itself

The dictionary's 1913 edition of the 1900 International, renamed Webster's Revised Unabridged Dictionary, has in modern times been used in various free online resources, as its copyright lapsed and it became public domain.

Surface tension

Surface tension (surface tension)
. (Physics) )
Sur"face ten"sion
  1. That property, due to molecular forces, which exists in the surface film of all liquids and tends to bring the contained volume into a form having the least superficial area. The thickness of this film, amounting to less than a thousandth of a millimeter, is considered to equal the radius of the sphere of molecular action, that is, the greatest distance at which there is cohesion between two particles. Particles lying below this film, being equally acted on from all sides, are in equilibrium as to forces of cohesion, but those in the film are on the whole attracted inward, and tension results.
