Fire is the rapid oxidation of a fuel (combustion) with associated flame, heat, and light. The flame itself is a thin region of gas where intense chemical reactions are taking place. The reacting gas in this area is often hot enough to glow visibly, although some flames can be nearly invisible. Typical flames are just incandescent gas, and are plasmas, because they are hot enough to be sufficiently ionized.

For example, when a lighter is held to a candle. This applied heat causes the fuel molecules in the wick to vaporize, in this state they can then readily react with oxygen in the air, which gives off enough heat in the subsequent exothermic reaction to vaporize yet more fuel, thus sustaining a consistent flame. The high temperature of the flame tears apart the vaporized fuel molecules, forming various incomplete combustion products and free radicals, these products then react with the oxidizer involved in the reaction. Sufficient energy in the flame will excite the electrons in the pre-combusted products, which results in the emission of visible light (see spectrum below for an explanation of which specific radical species produce which specific colors). As the combustion temperature of a flame increases, (if the flame contains small particles of unburnt carbon or other material) so does the average energy of the electromagnetic radiation given off by the flame (see blackbody).

Fire is made of a triangle (the triangle of fire). The three sides are : Heat, Fuel and Oxygen. You need all 3 to make fire. Hope this helps x

my goodness.... this question appears to be simple... yet it is taken me awhile to think about the answer.....

Actually fire can be made of anything that is flammable (which means, can easily form CO2 and H2O from O2). Fire itself is a product of a friction between two surfaces, that produces enough heat to combust/ react with the flammable reactants.

PS: I guess that is the most reasonable answer I can come up with XD~~

Fire is made from the combustion (burning) of a FUEL in the presence of OXYGEN and is started by a form of IGNITION - spark, flame, excessive heat, friction, .. etc

Fire is white/yellow/red hot particles of carbon reacting with oxygen to form CO2.
