What are flames ( as in fire) made of?

Answer 1

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.

Answer 2

Fire is burning gases, hot enough to produce light. Flame is made up mostly of oxygen, carbon dioxide, nitrogen and water vapor. It can be different colors depending on what is burning. All fire is made by a chemical reaction.

Answer 3

fire is due to rapid oxidation of whatever is burning. The flames are made of particles of the burning substance. The colour of the flame is determined by the elements in the substance that is burning.

Answer 4

Flames are simply the visible combustion products resulting from a "fire" which is the rapid oxidation of a material.

Answer 5

Fire is the result of a fuel such as wood having its molecules excited by combustion. Some of the combusted molecules fluoresce in the visible light spectrum as their free electrons escape. There are other aspects of the flames that release their energy in non visible energy such as ultraviolet and heat as well.

Answer 6

The flame's color (we only see its color) is due to the energy emitted by the fuel molecules when the electron of their atoms move from one energy level to another as a result of heat applied.

The heat we feel in fire is actuall the heat applied to and emitted by the electrons together with the colors they emit.

Answer 7

The flames that you see are made of glowing particles of ash and soot heated until they were so hot they glowed enough to give off light.

Answer 8

to make fire u have to have three things,its called the triangle 1st heat 2 oxygen 3 fuel......FIRE

Answer 9

the result of burning materials. They are the gasses given off in the burning

Answer 10

gases burning the colour of the flame depends on what you burn
