Capillarity \Cap`il*lar"i*ty\, n. [Cf. F. capillarit['e].]
   1. The quality or condition of being capillary.

   2. (Physics) The peculiar action by which the surface of a
      liquid, where it is in contact with a solid (as in a
      capillary tube), is elevated or depressed; capillary
      attraction.

   Note: Capillarity depends upon the relative attaction of the
         modecules of the liquid for each other and for those of
         the solid, and is especially observable in capillary
         tubes, where it determines the ascent or descent of the
         liquid above or below the level of the liquid which the
         tube is dipped; -- hence the name.
