Well,
I am a chemist. Fire is the rapid oxidation process that takes place when thin gs burn. The chemical reaction is what you see, the flame. An example of this would be Octane in your fuel to make the explosion neccessary to turn the crank shaft in your car. The balanced chemical reaction equation is:
C3H8 + 5O2 --> 3CO2 + 4H2O
The byproducts of the reaction is what we know as smoke, gasses, water vapours, light and heat. The more blue or the more clear the flame is (even the harder it is to see), the cleaner it is burning. The flames that you see on a camp fire is a reaction taking place, but it is incomplete combustion because it is giving off lots of carbon and not all Carbon Dioxide and Water. Hope this helps.
Wee Man.

Fire is, simply put, the fourth state of matter. It is also known as plasma.
Plasma is a mixture of ions and free electrons.
One important technical application is the magnetohydrodynamic electrical generator, where a flame is passed between the poles of a powerful magnet. Charged particles flow to the opposite poles, creating an electric current. The fact that such a device does not have any moving parts makes it highly reliable.

rFire is a rapid oxidation process that creates light, heat, and smoke, and varies in intensity. It is commonly used to describe either a fuel in a state of combustion (e.g., a campfire, or a lit fireplace or stove) or a violent, destructive and uncontrolled burning (e.g., in buildings or a wildfire). The discovery of making fire is considered one of the most important evolution of humankind, for it allowed higher hominids to ward off wild animals, cook food, and provide warmth as well as a source of light in darkness.
