chemical changes are those changes which do not take time to take change like burning of a candle and and forming wax from the candle ..
pure substance are the substance which do not have any mix element with them they are pure

pure substance and mixture
. Pure substances cannot be separated into any other kinds of matter, while a mixture is a combination of two or more pure substances. 2. A pure substance has constant physical and chemical properties, while mixtures have varying physical and chemical properties (i.e., boiling point and melting point).
fillteration -Filtration is the direct separation of the entire solution through a filter, where the solid is trapped on the filter and the liquid passes through.
Decantation.-Decantation is pouring the liquid away from a precipitated solid, keeping the solid in the original container.
