Cohesion \Co*he"sion\, n. [Cf. F. coh['e]sion. See {Cohere}.]
   1. The act or state of sticking together; close union.

   2. (Physics) That from of attraction by which the particles
      of a body are united throughout the mass, whether like or
      unlike; -- distinguished from adhesion, which unites

            which, being increased, turns a fluid into a solid.
