Ice \Ice\ ([imac]s), n. [OE. is, iis, AS. [imac]s; aksin to D.
   ijs, G. eis, OHG. [imac]s, Icel. [imac]ss, Sw. is, Dan. iis,
   and perh. to E. iron.]
   1. Water or other fluid frozen or reduced to the solid state
      by cold; frozen water. It is a white or transparent
      colorless substance, crystalline, brittle, and viscoidal.
      Its specific gravity (0.92, that of water at 4[deg] C.
      being 1.0) being less than that of water, ice floats.
      [1913 Webster]

   Note: Water freezes at 32[deg] F. or 0[deg] Cent., and ice
         melts at the same temperature. Ice owes its cooling
         properties to the large amount of heat required to melt
         it.
         [1913 Webster]
