Is Burning Candle Wax a Physical or Chemical Change?

Answer

Melting candle wax is a physical change because when a candle is burning, the flame melts the wax. The wax goes from solid to liquid, but it is always wax, just in different forms If the melted was cools again, it will go back to being the same solid wax as before. a physical change is when the same compound changes form but the compound is completely unchanged while a chemical change is when bonds have changed and the molecule that existed is completely different

The physical change occurs when the heat displaces the bonds that solidify the wax. Upon cooling, the wax is able to form the bond again. The chemical changes are much more complex.
