Question

In science, what is the structure of fire?

Is it ions? Or protons? Or quarks? Or another?

There are no any article about science of fire in encyclopedia and wikipedia...

Thus, I hope that any one scientist can help me to explain it.

Thank you.

Answer 1

fire is a plasma state, a superheated gas state.

the reason we see fire is that fire is an energy source as well, that is why we see the fire, it gives off light because of electrons vibrating, which gives off photons.

Answer 2

Fire is usually an oxidation chemical reaction.  Various compounds of carbon and hydrogen form covalent bonds with oxygen.  It is exothermic, meaning it releases more heat than it consumes.  I'm not sure what you mean by the structure of a chemical reaction.  Some samples:

C + O2 -> CO2

2H2 + O2 -> 2H2O

Answer 3

fire is simply a (complicated) chemical reaction involving molecules, specifically an oxidation reaction ( reaction with oxygen). Of course, the reaction emits light which is the visible flame.

Answer 4
