It is a chemical reaction that happens in a mixture of gases. Simply defined, fire is a chemical reaction in a mixture of incandescent gases, typically luminous with intense heat. All fires eventually burn themselves out, unlike solids, liquids, and gases, which can exist indefinitely in the same state. As the gas mixture warms, it also rises and gives the flame its familiar teardrop taper.

The fire starts at that boundary, and then reaches a steady state: the rate of oxygen entering the mixture, the rate of gas entering the mixture, and the rate of the CO2 and water vapor being emitted stay the same. The unknowns provide atmospheric chemists and engineers research opportunities to isolate the precise chemical processes involved in combustion — and the prospect of impacting the economy and the environment.
