Why is there more smoke when a fire goes out?

This is because of the heating of the earth’s surface during the day. The air just above the surface becomes heated and expands. In turn, it begins to rise, since it is lighter, resulting in vertical movement in the atmosphere. The more unstable, the higher smoke will be lifted.

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 match work?

Basically when you shake the match violently you move the fire away from its source of fuel. The flames themselves will have some momentum which you can see from the way the flame “tilts” as you move the match. When you move the match very quickly you move the source of fuel faster than the flames can readjust course.

What smoke comes out of matches?

As antimony oxidizes, sulfur oxides form, creating that burnt-match scent. The smoke you’re seeing is actually tiny unburned particles resulting from an incomplete combustion. Individually, they’re a little bit too small to see but grouped together, they form smoke. There’s also some water vapor in there.

Why does some wood smoke more than others?

The density of wood, of course, refers to the amount of organic matter it contains. With more organic matter, hardwood varieties contain more fuel than their softwood counterparts. Therefore, they are able to burn brighter and hotter to create a more complete combustion process.

What is the smell after blowing out candle?

But what about the smell? Ricky – The smell you get from a burning candle is due to the tiny proportion of pyrolysis products that didn’t burn properly in the flame. 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.

Is fire possible by blowing?

If the air consists no oxygen, there is no chance of continuing combustion as oxygen is totally absent. So, blowing other gases like carbon dioxide etc extinguishes fire.

Do matches produce smoke?

When the flame is going, most of that is being consumed by the combustion process and reduced to a soot that is too sparse and fine to see. Blow out the flame, and the hot wooden match is still giving off that charred vapor, which rises as smoke until the match cools and stops producing it.

Why is smoke white or black?

The type of fuel and how hot it’s burning. In general, a hotter fire will convert more fuel into elemental carbon, which forms into tiny particles that absorb light and appear in the sky as black smoke. These tend to reflect light, making the smoke look white.

Why do candles smoke when they blow out?

Again, this is so you maximize the amount of wax vapor around the wick and have a clear smoke trail to follow. This fire trick is based on how candles work. When you light a candle, the heat from the flame vaporizes the candle wax. When you blow the candle out, vaporized wax briefly remains in the air.

Why does blowing on a flame stop it from burning?

This is because the flame is boiling the wax, which becomes a vapor, which then burns. All of these processes are driven by the heat from the flame. As you blow on the flame, you moving it away from the wax and disrupt this process.

How does the traveling flame trick work?

How the Traveling Flame Trick Works This fire trick is based on how candles work. When you light a candle, the heat from the flame vaporizes the candle wax. When you blow the candle out, vaporized wax briefly remains in the air.

How does the candle fire trick work?

This fire trick is based on how candles work. When you light a candle, the heat from the flame vaporizes the candle wax. When you blow the candle out, vaporized wax briefly remains in the air. If you apply a heat source quickly enough, you can ignite the wax and use that reaction to relight the wick of the candle.
