This is because the wax oxidizes (burns) in the flame to yield water and carbon dioxide, which dissipate in the air around the candle, in a reaction which also yields light and heat. Candle wax (paraffin) is composed of chains of connected carbon atoms surrounded by hydrogen atoms. These hydrocarbon molecules can burn completely. First the heat of the flame vaporizes the wax molecules and then they react with the oxygen in the air. As long as the wax doesn't melt away from the flame, the flame will consume it completely and leave no ash or wax residue.

∙ 13y agoWhen a candle is lit, two different things happen to the wax that it is made of. Some of the wax combusts (burns), which produces the flame at the top of the candle; and some of the wax melts (which may cause it to slide away from the heat, and not end up burning).

∙ 10y agoBurning wax turns into gas. Most candles are made of paraffin which is made from petroleum and consists of hydrocarbons. When it burns, the combustion products are mostly carbon dioxide and water vapor, both of which enter the atmosphere as invisible gas. There can be other combustion by-products, but they will also be in the form of gas. There are no solid by-products to create ashes.

∙ 15y agoSome of the wax turns into liquid and then turns back to a solid. The volitile (flammable) portions turn into a gas which burns, hydorgen. * oxygen * carbon dixoide

What burns on a candle the wick or the wax?
the wick Burns but it produces heat that melts the wax
Where is the wax of the candle going?
It vapourises and burns.
What changes do you see when a candle burns?
The wax on the candle can turn in a gas
Where does the wax of a candle goes when it burns?
As the candle is burning, some of the wax melts and turns into a gas in the atmosphere.
What form of energy is being used as a candle burns?
The chemical energy stored in the candle wax.
What burns on a candle the wick or the wax?
the wick Burns but it produces heat that melts the wax
What does the wax of a candle react with when it burns?
Oxygen.
Where is the wax of the candle going?
It vapourises and burns.
What changes do you see when a candle burns?
The wax on the candle can turn in a gas
Where does the wax of a candle goes when it burns?
As the candle is burning, some of the wax melts and turns into a gas in the atmosphere.
How does a candle change physically?
As a candle burns, the candle becomes smaller as the wax melts.
What physical and chemical changes occur when a wax candle burn?
Some wax burns, and as it does so, chemical changes occurs. Wax converts to CO2, CO, and H2O. That is an exothermic reaction The rest of the wax melts with the increased temperature. That is the physical change.
What physical changes happen when a candle is lit?
There are many things that physically chance when a candle burns. The wick burns, and turns into ash, and wax of the candle melts and runs down the sides of the candle or container.
What form of energy is being used as a candle burns?
The chemical energy stored in the candle wax.
Does the color of wax on a candle matter how fast it burns?
Maybe Maybe NOT
What form of energy is produced when you use the candle?
When you light a candle, it burns the wax. That is chemical energy. The thermal energy is produced as the lighted wick continue to burn the wax. It also gives out light as it burns.
Why did the smoke from the extinguished candle reignite the candle?
because, when the wax is lit it burns off as a vapor, when the candle was extinguished the wax vapor was still in the air, and the wax acts as fuel for the flame of a candle, so the flame combusted and lit the vapor, leading back to the candle wick.
