What Form of Matter Is Fire?

Question

Is fire a solid, liquid, or a gas?

Answer 1

This question puzzled me for years after learning that solid, liquid or gas are the only forms of matter. That actually isn't true, obviously. It took me a long time to learn the answer, before the Internet (lol).

Fire is a chemical reaction. It is the actual burning of whatever fuel is present (wax in a candle, for example). The candle is the fuel for the chemical reaction along with oxygen in the air. The flame is the reaction, a chemical reaction. I thought that was fascinating.

Answer 2

the following is a Wikipedia definition:

A flame is an exothermic, self-sustaining, oxidizing chemical reaction producing energy and glowing hot matter, of which a very small portion is plasma. It consists of reacting gases and solids emitting visible and infrared light, the frequency spectrum of which depends on the chemical composition of the burning elements and intermediate reaction products.

Answer 3

There are 4 elementals of universal creation:
earth elemental, water elemental, air elemental
and fire elemental.

They are respectively solid, liquid, gas, and, well... fire.
As you can see fire is all by itself.

Answer 4

The flame itself is gas. The fuel can be gas, solid oror liquid.

Answer 5

neither.
fire is what we call ENERGY
not matter
