Explain about Suspensions

Sol is a colloidal system, in which solid particles are dispersed in a liquid. When the particles of a solid are separated into large aggregates of particles and dispersed in a liquid, the food system is referred to as a suspension. In a suspension, the particles tend to sink to the bottom of the mixture if they are heavier than the liquid but rise to the top if they are lighter. A mixture of flour and water is an example of a mixture in which the particles are heavier than the liquid. If it is stirred and heated,  a suspension of this kind will change to a gel.
