Candle wax burning is a chemical change. During the process of burning, the wax undergoes a chemical reaction with oxygen from the air, resulting in the formation of new substances and the release of energy in the form of heat and light. This to due to the fact that candle waxes is a hydrocarbon compound , namely, it is the paraffin wax.
Therefore, to be more specific, the combustion equation can be written as follows:
Paraffin Wax (C25H52) + Oxygen (O2) → Carbon Dioxide (CO2) + Water Vapor (H2O)

∙ 15y agoIt is a chemical change because you can't put it back together exactly the way it was before. Yes, a chemical change is taking place.
Even simple cooking produces chemical changes.
The smoke and the temperature change are good signs a chemical change is taking place

Is candle burning physical change?
Physical change means change physically while chemical change means change chemically or change in chemical properties.Like if you would drop a chip of zinc in sulphuric acid it will its color will be changed which is no doubt a physical change.But,also its properties are changed as it will be transformed into zinc sulphate from simple zinc,thus it also undergoes a chemical change. Now,with your question,the candle breaks but the candle remains the candle,so,its not a chemical change but a physical change only.Hope it helps!
