One instance of a practical application of melting wax is in candles. Candles have a wick that does not burn, but rather allows the wax to be sucked up the length of the wick and vaporized, and it is the wax vapor that burns when we see a candle. If wax did not melt, it would not be able to be drawn up the wick in candles, and there would have to be a different design or different material used for all types of candle.
Another interesting application could be in coffee cups. Wax absorbs a certain amount of heat when it melts, so if a layer of wax were held between two layers of a coffee cup, it could ideally melt and bring the coffee down to some ideal temperature fairly quickly. Because it is only some certain amount of wax that is being melted, it would then level off at this desired temperature and not cool the beverage too much.
There are certainly more real world applications for melting wax, and it just takes a bit of imagination to discover them.

Why the melting point of candle wax cannot be too high?
Candles contain organic compounds with low melting points.
Is melting of wax is chemical change or physical?
Yes it is!:Pwhen a candle is lighted the solid wax changes into liquid wax,then it turns into vapour to produce flame.new substances like Co2 and H2O are formed alongwith the evoulation of light and heat.
