It is made up of hot fragments of whatever material is burning, products of incomplete combustion and free radicals.

i asked this question to several teachers and they replied gas. i think it is just the electrons in an excited state and other sub atomic matter plus the extra heat.

Fire, or flame, is primarily an extremely hot gas, even hot enough to give off light. It is mainly composed of oxygen, carbon dioxide, nitrogen, and water vapor.Fire is a chemical reaction which creates a burst of heat and light. This is called ignition point, and what we see is a flame. When heat changes the state or shape of an objects, we call this combustion.There are three main elements which are required to ignite a flame. Without any of these three elements, it is not possible to start a fire. These three elements are: Oxygen, Fuel and Heat.
OR
A fire or flame typically occurs when combustible airborne chemicals (fuels) oxidize (or burn) in such a way that heat is released (exothermic) and the electron activity or the temperature (incandescence) of the reaction emits visible light. The fire is the volume in the air where the chemicals are reacting in this way and emitting light. So, I guess the best answer I can give is that fire is made of vigorous chemical reactions.
Most fires also "feed" themselves because the heat produced by the flame drives more fuel particles from a solid or liquid source into the air.
Note that it is possible to have an invisible "fire" if the fuel burns in a way that does not produce visible light. Some alcohols burn with invisible flame - but that is not what people typically imagine when they think of fire. This kind of fire is also the region/volume of vigorous exothermic chemical reaction.
It is also possible to have fire without oxygen by combining other reactive chemicals, but in our atmosphere burning by oxidation is by far the most common phenomenon. It is also possible to have fire outside our atmosphere (no air), but the principles are essentially the same: mix stuff, chemical reaction makes heat and typically light.

God does not care about our mathematical difficulties. He integrates empirically. ~~~Albert Einstein (1879-1955)~~~~
To divide a cube into two other cubes, a fourth power or in general any power whatever into two powers of the same denomination above the second is impossible, and I have assuredly found an admirable proof of this, but the margin is too narrow to contain it.~~~Pierre de Fermat (1601-1665)~~~
