The heat from the wick melts the wax which gets absorbed in the wick and then gets burnt (which is really oxidation) to produce heat energy<span> as well as light </span>energy. The energy<span> transforms from chemical </span>energy<span> to heat and light </span>energy<span>. Because when the </span>candle burns<span> a chemical reaction </span>occurs<span>, and produces heat and light.
