Some wax burns, and as it does so, chemical changes occurs. Wax converts to CO2, CO, and H2O. That is an exothermic reaction The rest of the wax melts with the increased temperature. That is the physical change.
What evidence is there when a candle burns that a physical change takes place?

What is the chemical reaction when you burn a candle?
When a candle burns the reactions that occur are both chemical and physical. Chemical reaction is when substances are mixed together to create a different material. A physical reaction is when there is a change in the appearance of the substance. For example when water turns to ice, and when chocolate melts. The chemical reaction that happens when a candle burns is when the oxygen combines with the paraffin. When this happens, this makes carbon dioxide, water and other materials. When the wax reacts with the oxygen it gives off light and heat. The more oxygen that reacts with the candle when it burns, the brighter and hotter it is. The physical reaction that occurs is when the candle wax melts. When the energy (light and heat) inside of the candle is released it helps to melt the candle.
