Why does a candle relight when you touch a match to the smoke?

When we light the candle at the candle wick, the flame of the match first heats the wax in the wick (or near the wick) to a temperature at which it first liquefies and then becomes a gas. Once the wax has become a gas and mixes with the oxygen in the air, the heat from the match ignites the mixture of gaseous wax.

Why does my candle spark when I light it?

If this is the case, you probably have been lighting your candles for way too long and not trimming the wick. This is the result of the candle consuming more wax than it can burn. Lighting a “mushroom” can lead a wick to crackle and pop and release soot into the air and onto your candle container.

How does a candle relight without touching the wick?

Procedure

1. Set each candle in its holder (if necessary)
2. Put on your protective goggles.
3. Light the first candle with the grilling lighter.
4. Blow it out.
5. Immediately hold the lighter in the smoke directly over the candle and pull the trigger.
6. Watch to see if the candle relights by lighting the smoke.

Why did the smoke ignite while the candle without smoke did not?

Here is his explanation: 1) When you are burning a candle, you are essentially vaporizing the liquid wax into a gas that is flammable. This vapor can then be used as fuel for the candle flame. 3) Therefore, as you hold a flame close to the smoke it will light the unused wax vapor that is in the smoke.

How many times can you relight a candle?

Limit a candle’s burn for no more than 4 hours at a time. The best solution is extinguish the candle after 3 hours, let it cool for a little bit, then relight it again. 5.

What happens when you lighted the candle stick?

The heat of the flame vaporizes the liquid wax (turns it into a hot gas), and starts to break down the hydrocarbons into molecules of hydrogen and carbon. These vaporized molecules are drawn up into the flame, where they react with oxygen from the air to create heat, light, water vapor (H2O) and carbon dioxide (CO2).

Why do candles only smoke when blown out?

When a candle was blown out, the flame stops immediately but the wick and the wax are both still hot, so pyrolysis continues for a few seconds. The solid particles and smelly gases are produced for a moment, but with no flame to burn them, they rise like smoke.

Why does blowing out a candle work?

Carbon dioxide molecules are heavier than air. Because of this, they push the oxygen and other molecules in the air out of the way as they sink down over the flame and candle. When oxygen is pushed away from the wick, it can’t react with the wax anymore. This makes the flame go out.
