Combustion after the appliance of a flame is maintained by the wax. Without the wax, the wick would be consumed in a matter of seconds. In order to slow the progression of the flame, wax impedes the fame. To keep the flame from burning out, once the wax becomes liquid, it will boil and give off a slight composition of combustible gases. Wax is flammable. Once the candle burns down, the wax at the bottom doesn't melt as easily as the top due to the constant heating and cooling cycles. Therefore, the flame is essentially snuffed out because the wick cannot burn any further as solid wax yields to a lower temperature than the wick can maintain. The wick basically gets too short.

∙ 14y agoIt actually does, but it won't touch the actual wax of the candle below it. Because the wick is mainly there just to provide a source for the flame. The heat of the flame melts the wax beneath it, and it continues to burn because the wax vapours give the flame a fuel source.

Why does the wick turn black when a candle burns?
Because the flame is scorching the wick.
Why does candle wax disappear?
When the candle flame is burning, the flame heats the wax which melts it, the wick pulls in the liquid wax into the flame as fuel (this is why the wick doesn't just burn away). Think of a napkin soaking up water. The wax then burns in the flame and "disappears".
What does a candle need to stay lit?
Make sure you are not close to any wind!!!!!! In addition, oxygen and the wick are needed to continue the flame. If the wick runs out, or if the candle is put in an oxygen-free environment the candle will burn out.
Why do short candle wicks have short flames?
Because if the wick is shorter, the flame has less space to cover?
How does a candle's flame work?
Heat from the flame melts the wax in the wick. As the melted wax vapourises, and is burnt, it is replaced by more melted wax travelling up the wick by capilliary action. As long as the flame remains, the process simply continues.
Is a candle wick nessary?
Yes a candle wick is necessary to get the candle flame. The molten wax ascends the wick by capillary force and burns to create the flame.

Where does a lighted candle get its energy to give off light and heat?
The lighted candle burns wax for fuel. The heat from the flame melts the nearby wax, and it is drawn to the flame through the wick. The wick is slowly consumed by the flame, but the wax is the main fuel.
How do you shoot the candle flame in wild west island?
first you shoot the wick.
Is a wax candle waterproof?
The wax itself should be, but the flame is not. The wick is not either.

Does the flame destroy the candle?
No. It just makes the wick burn slower. However, technically part of the candle is "destroyed" hence why you can smell the scent of the candle.

Is lighting a candles wick with a match a conduction and convection?
it could be either convection or radiation that can light a candle wick with a match.The match stick does not retain enough heat by itself to light a wick by conduction. The burning match though gives off enough heat to incandesce the air around the match into a flame. By contact of this convective hot gas (flame) with the wick the temperature of the candle wax can be raised to the ignition temperature. By holding the match close to the wick, without the flame contacting it, the radiant heat from the flame can vaporize and ignite the wax as well. The closer the flame to the wick the more radiant heat can be transferred.
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.
