Eli5: How come fire flames go upwards and why do the flames always “dance” around?
In: 285
The light you see is the shape at which the hydrocarbon gas makes contact with the surrounding oxygen.
The hydrocarbon gas is created when fuel is evaporated from the heat of the light aka the chemical reaction.
This hot gas rises up. The outermost layer of gas hits oxygen first, then the next layer and so on making a cone.
Without any wind or irregular supply of fuel, this would be a perfect cone. Without gravity, it’s a perfect sphere.
