Explain sol -gel transformation

During sol -gel transformation, a three dimensional network is formed by the interlocking of dispersed particles. The liquid phase is entrapped in the interstitial areas of this structure. When this happens, the sol loses its fluidity and becomes a gel. The change from sol to gel may be brought about by a change in the concentration of dispersed phase or a change in temperature .Gelatin dispersed  in hot water is a sol, but when cooled it becomes a rigid, transparent gel. Other examples of sols that turn to gels are fruit jellies and custards.
