"Burning of anything is a chemical change"- analyse this statement.

Let off think of burning a candle made with wax. Wax is a mixture of various hydrocarbons. Organic compounds made of hydrogen and carbon are known as hydrocarbons. In the burning of a wax, three States of matter can be observed simultaneously. There is a a thin liner inside the wax. When we add fire to it, the hydrocarbon particles around the liner melt into liquid. The liquid wax absorbs heat and vaporizes first. Then the vaporizes wax starts the reaction with oxygen of air and produces carbon dioxide, water vapor, light and heat.
Therefore burning anything is chemical change.
