From physical point of view

The fire was always interesting to people and people tried to conquer it and to use it from the first moments they saw it. And it is necessary to say that they really succeeded.
The fire is the combination of the scorching gas and plasma that are released in the result of the free or involuntary heating of the combustible material to the certain point, the chemical reaction, and the touch of the high-tension current with the combustible material.
The fire is the main base of the burning process and has the quality to self-spread thanks to the touched combustible material. The proper temperature of the fire depends on the source that provoked the reaction of inflammation or on the material that takes part in the reaction of burning.
The fire is possible thanks to the atmosphere we have and the oxygen it contains. Fire is unable to burn in the place where there is no oxygen. The chemical reaction of burning consists in the taking the oxygen that is changed into carbon dioxide in the result of burning.
The combustible material may be everything from the chemical acids to the ordinary wooden things and fabrics.
The way to put out the fire depends on the source of its inflammation. For example it is forbidden to put out the fire with the water if it started from the current influence. If you do that it will start to burn with new power.
The fire is the stage of burning that may cause serious damages and injuries.
