What is Fire, (As in a Naked Flame)?
What is it, Liquid, solid, gas?
How is it made?
How is it Maintained?
Answers:
FIRE is rapid oxidation. It is a chemical reaction between oxygen and other materials (solid or liquid). The flame you see is the point at which the material is converted into a gas. This point is called the sublime.
To maintain sublimation (flame) you must have a constant supply of materials (solid or liquid) and a constant supply of oxygen.
Fire is made by raising the temperature of a material (solid or liquid) to its point of sublimation in an oxygen filled enviornment.
FYI, RUST is slow oxidation
Fire is neither gas, solid nor liquid. It is a sort of illusion: there is nothing there, although you can see it. It's sort of like a heat wave- think of it as thermal imaging.
Fire is produced my extreme heat, where a material combusts. Any combustion needs oxygen from the air to burn- with out oxygen, there is no fire.
By the way, a common misconception is that when you throw water on a fire, you are putting out the FLAMES. Infact, you are putting out water ever is on fire and cooling it. Without heat, fire can not be made.
Alos, a little extra, you know you have CO2 fire extinguishers, that's a gas inside. It does not work like water- the CO2 (carbon dioxide) is actually extremely cold. As it is jetted onto a fire, it restricts the oxygen to the material, making combustion, and hence fire, impossible.
It is a rapid exothermic chemical reaction that produces heat and light. What you see is the light given off by the reaction.
The flame is a glowing gas. It glows due to the heat given off by a combustion reaction (i.e. burning). To maintain the flame, you need to maintain the combustion reaction that produces the heat - meaning the fuel must not be depleted, and there needs to be sufficient oxygen.
A flame is the gaseous products of combustion (usually carbon dioxide and steam) which are so hot that they are radiating in the visible spectrum. So a flame is a mixture of very hot gases.
Flame is a low-temperature 'partial plasma', which is a distinct state from solid, liquid or gas. It is usually formed by ionising a gas, which means electrons have been separated from their molecules/atoms. It is maintained as described in the other answers!
