Gel
solid jelly-like material that can have properties ranging from soft and weak to hard and tough. Gels are defined as a substantially dilute cross-linked system, which exhibits no flow when in the steady-state
A gel is a semi-solid substance material which usually wobbles.
By weight, gels are mostly liquid. But gels also behave like solids. They have a three-dimensional cross-linked network within the liquid. It is the crosslinks in the fluid that give a gel its structure.
As colloids, gels are a dispersion of molecules of a liquid within a solid. In a gel, the solid is the continuous phase; the liquid is the discontinuous phase.
Examples: Jellies, agar, contact lenses, organic slime.
