Not sure if this is actually a chemistry question so excuse the flair if it’s wrong. I’ve heard that blowing slowly on a fire introduces more oxygen into it, which is needed to grow the fire. But don’t we breathe out carbon dioxide???
And when you blow quickly, I suppose you’re separating/distributing the embers but I need someone to confirm this and elaborate further.
In: Chemistry
The air you breathe out still contains oxygen, your lungs dont use all oxygen you breathed it. Just a part of it gets replaced by carbon dioxide.
If you blow quickly, you seperate the flame from its fuel, causing the fuel to cool down, so that it does not burn anymore (and the existing flame vanishes, as it has nomore fuel).
