D-It will become a temporary magnet because the domains will easily realign.
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.
