Explain the following:- (a) tyndall effect (b) crystallization and (c)

1.	Explain the following:- (a) tyndall effect (b) crystallization and (c) elements and compounds
Answer» \tTyndall 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.\tCrystallisation: The process of formation of crystals from a hot saturated solution by cooling.\xa0This 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.\t\tAn element can be defined as a basic form of matter which cannot be broken down into simpler substances by any physical or chemical means.\xa0A compound is a pure substance composed of two or more elements combined chemically in a fixed proportion by mass. \t
