Tyndall effect can be defined as the scattering of a beam of light by colloidal particles present in a colloidal solution. Tyndall effect can also be observed when a fine beam of light enters a room through a small hole.
Crystallisation: The process of formation of crystals from a hot saturated solution by cooling. This method involves dissolving the mixture completely in water and heating this mixture. Further, cooling of this mixture results in the formation of crystals of a less soluble solid on the surface of the solution.
An element can be defined as a basic form of matter which cannot be broken down into simpler substances by any physical or chemical means. A compound is a pure substance composed of two or more elements combined chemically in a fixed proportion by mass.
