Encyclopedia Article for gel

coherent mass consisting of a liquid in which particles too small to be seen in an ordinary optical microscope are either dispersed or arranged in a fine network throughout the mass. A gel may be notably elastic and jellylike (as gelatin or fruit jelly), or quite solid and rigid (as silica gel, a material that looks like coarse white sand and is used as a dehumidifier). Gels are colloids (aggregates of fine particles, as described above, dispersed in a continuous medium) in which the liquid medium has become viscous enough to behave more or less as a solid. Contraction of a gel, causing separation of liquid from it, is called syneresis. Compare sol
