What is Gel?
A '''gel''' is a semi-solid substance material which usually [[wikt:wobble|wobbles]]. By weight, gels are mostly [[liquid]]. But gels also behave like solids. They have a three-dimensional [[cross-link]]ed [[network]] within the liquid. It is the crosslinks in the [[fluid]] that give a gel its structure. As [[colloid]]s, gels are a [[dispersion]] of [[molecules]] of a liquid within a solid. In a gel, the solid is the [[wikt:continuous|continuous]] [[States of matter|phase]]; the liquid is the discontinuous phase. Examples: [[Jelly|Jellies]], [[agar]], [[contact lens]]es, [[Organic matter|organic]] [[slime]]. {{sci-stub}} [[Category:Physical chemistry]] [[Category:Materials]]
