What energy is being transformed to heat when you burn a candle?

This would be chemical energy that is converted to heat. 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 as well as light energy.

4$\begingroup$ ""The heat from the wick melts the wax "" Nonsense! The heat conduction by the fabric of the wick is much too small! The wax is molten by radiated heat (IR) ! ""the wax which gets absorbed in the wick"" another nonsense, look up meaning of "absorbed". $\endgroup$– GeorgCommented May 21, 2011 at 9:57

1$\begingroup$ Thanks for the clarification. You are right -- its radiated heat. I learned something from you, bow in your general direction, and stand corrected. $\endgroup$– SaiCommented May 21, 2011 at 15:16

1$\begingroup$ @David: Thanks. Anyway I learned something and got a chance to use a Monty Python reference. So not complaining :) $\endgroup$– SaiCommented May 25, 2011 at 1:23

The energy transforms from chemical energy to heat and light energy. Because when the candle burns a chemical reaction occurs, and produces heat and light.

$\begingroup$ You need to provide more detail about what happens in a chemical reaction. $\endgroup$– Bill NCommented Mar 17, 2016 at 3:48
