Why does the candle relight when you put burning match near the smoke?

The smoke from the candle has vaporized wax, which is highly flammable vs carbon soot. When the flame touches the stream of vaporized wax (smoke) the heat is transferred back to the wick relighting it.

Why is there still smoke coming out a candle after it is gone out?
When a candle "goes out" the burning of the wax has stopped, but there is still some burning of the wick material. Typically this burning is less intense and less "clean" than the burning of the wax and gives off more smoke. Once the wick stops burning, there should not be any more smoke.
When burning a candle where does the smoke originate?
The wax and the wick burn, but not completely, the unburnt part being mainly carbon n the form of very small particles. These are quite hot and glow white, yellow, and red, and are resonsible for the 'flame' and its colour. After the particles leave the immediate area of the flame they cool down and don't glow any more. They are now the smoke.
What are the Qualitative observation before and during burning of a candle?
Before burning, the candle appears solid, with a wick protruding from the top. During burning, the candle's wax melts and the wick ignites, producing a flame and releasing heat and light. The flame may flicker and produce smoke as it consumes the wax.
Why can you light a candle by putting a match flame in the smoke of a candle which has been blown out?
A very good question my freind and im surprised no one has given you the answer. This is very unusual thing since smoke is carbon dioxide and is NOT flamable but however the candle is coated in "proffin" so its the proffin in the smoke that causes the candle to light back up. im not registerd to this site i just thought i would answer your Q if you had any other Q's or wanted to thank me my email is: j0k3r@live.com that is a zero not an o lol WRONG /\ Actually, smoke is quite flammable. Smoke is generally seen from fires that are burning every inefficiently (such as one that is just put), thus the smoke contains a lot of the unburnt fuel. Efficient fires to not produce smoke. Anyway, the smoke from the blown out candle is fuel...as it travels upwards it mixes with the oxygen in the air...thus we have two side of the fire triangle. However, since you cooled the candle (by blowing on it) you removed the last part, the heat; thus combustion stopped. When you light the smoke with a match, you re-introduce the heat and combustion begins anew. Never heard of "proffin" nor was I able to find it on google or anywhere. Did you mean paraffin? Candles are made of paraffin (that is actually what burns) the wick allows the flame to be incident on the surface of the wax; the wax vaporizes and is actually what burns not the wick. -nickccoates@gmail.com
Which common examples can you think of where burning happens in everyday life?
Common examples of burning in everyday life include lighting a candle, cooking food on a stove, using a fireplace, and burning a match to create fire. Additionally, burning can occur in the form of incense sticks, smoke from cigarette or electronic smoking devices, and even when using a lighter.

Why does a candle smoke when it's blown out but not while it's burning?
When a candle is blown out, the wick continues to smolder and release smoke due to incomplete combustion of the wax. While the candle is burning, the flame consumes the wax efficiently, leaving no leftover material to create smoke.
Black smoke from candle physical change or chemical change?
The black smoke produced from a burning candle is a physical change. This is because the change in appearance (from no smoke to black smoke) does not involve a change in the chemical composition of the candle wax or the oxygen in the air. The black smoke is primarily made up of tiny carbon particles that result from incomplete combustion of the candle wax.

How does the air above a burning candle feel?
The air above a burning candle can feel warmer than the surrounding air due to the heat generated by the flame. It may also feel slightly different in terms of air quality, as the burning process releases smoke, soot, and other combustion byproducts.
What happens when you put salt on a burning candle?
Putting salt on a burning candle can help extinguish the flame by cutting off the oxygen supply. The salt melts and can create a crust over the wick, preventing it from burning. However, adding salt can also generate some smoke and may produce a foul smell.
What does a candle let out?
A candle when it burns lets out smoke.
Can you relight a Black And Mild?
Yes but it will be harsh and most likely unpleasant to smoke.
Why is burning a candle chemical change?
Burning a candle is a chemical change because the wax in the candle undergoes combustion, reacting with oxygen in the air to form new substances like carbon dioxide, water vapor, and heat. This process involves breaking and forming chemical bonds, leading to a irreversible change in the chemical composition of the wax.
