What is a mojor difference between a sol and gel
Answers
A gel is a complex fluid consisting of two or more phases typically composed of a solid dispersed in a liquid. Sol is the liquid state of a colloid solution. Gel can be described as solid or semi-solid (jelly-like) stage of a colloidal solution. The sol can be converted to gel by cooling.

Answer:
A sol is a colloidal solution suspension of very small solid particles in a continuous liquid medium. Sols are quite stable and show the Tyndall Effect. Tyndall Effect is the scattering of visible light by colloidal particles. Artificial sols may be prepared by dispersion or condensation. Dispersion techniques include grinding solids to colloidal dimensions by ball milling and Bredig’s arc method (whereby an arc is struck between electrodes under the surface of water containing some stabilizing agents). A sol generally has a liquid as the dispersing medium and solid as a dispersed phase.
