Burning of candle is physical change or chemical change

As all told it is both physical and chemical change.
Burning a candle involves both physical and chemical changes.
it is both chemical as well as physical change as
thumbzz up plzzz
The physical changes in the candle is that the wax melts, then freezes back into solid state again, and the chemical changes are that the wick burns, soot, and smoke. water vapor and carbon dioxide are formed. and When the wax burns, and the wax combines with the oxygen to form CO2, carbon monoxide, carbon particles (incomplete burning/oxidation) and water. After it burns, you can 't get the wax back.
hence it is both physical and a chemical change
As we know
Chemical Change- is when something can not be changed back to its normal self
Physical Change- is when it can turn back in to its normal self
So burning of candle is involves both physical and chemical changes.
The wick is burnt, so by definition involves a chemical change. Specifically, this is the reaction of the fibre and oxygen in the air forming carbon oxides and water.
And the physical changes are the wax being melted and some of it vapourised; the same chemical change as above also takes place, as some of this vapour is burnt along with the wick.
In other way : you can say the wax has to be vapourised in order to react with oxygen. The wick is just there to soak up the melting wax and lift it up to reach the oxygen.
The flame is above the top of the candle: the vapourised wax is what is burning.
it is physical change. because after the candle is burnt new material is not formed
