Why do you think the flame goes out when we put a jar over the candle? Placing a jar over the candle limits the amount of oxygen in the air around the candle. Without enough oxygen to react with the wax, the chemical reaction cannot take place and the candle cannot burn. When a candle burns for a while, it eventually gets smaller and smaller.
Melting, on the other hand, is a change of state, when you melt water it maintains the same chemical formula, but the bonds between the molecules are broken. If enough heat is applied pretty much anything will melt, but most things that burn do so because of their carbon content; carbon has a melting point of 3500 o C, so a chunk of wood would ...
