What Does fire Mean
From the Latin focus , fire is the heat and light produced by combustion . Fire is born from a chemical oxidation reaction and involves the generation of flames and the emanation of water vapor and carbon dioxide. It could be said that fire is the visual manifestation of the aforementioned combustion process.
The flash point is known as the temperature at which a material catches fire. When the oxidation reaction begins, the heat that is given off allows the fire to be maintained for a certain period of time . The amount of energy produced by a fuel can be expressed by its calorific value .
The temperature and color of the flame depend on the type of gases evolved during the combustion process. Wood, when burning, generates orange, red and yellow flames. Hydrocarbons, on the other hand, tend to produce bluish flames.
The cultural value of fire in the development of man is incalculable. Anthropologists believe that human beings became aware of their superiority over other animals by dominating fire. When man discovered how to generate it, he began to use it to produce heat and defend himself, since the animals flee from the flames.
The friction was the original method for lighting a fire, followed by percussion (two stones collide to produce a spark). Currently, it can ignite fire with tools such as matches or matches and lighters .
In addition to all the above, we cannot ignore that the term fire is also used to refer to the burners that are used in the kitchen to prepare any dish.
In the same way, we must not forget that, within what would be the field of Alchemy or Western Cosmogony (scientific theory that deals with the origins and creation of the World), it is established that fire is one of the four fundamental elements . Thus, it is always presented in conjunction with water, land and air.
It is no less interesting to note that there is an expression that is used with some frequency, that is part of our cultural heritage and that makes use of the term that we are now analyzing in depth. We are referring to the so-called “wisp”. This is a phenomenon that occurs mainly in cemeteries and swamps and that basically consists of the birth of small flames that float a few meters from the ground.
Those are flames that are produced when matters that are in the process of putrefaction, whether vegetable or animal, ignite.
Likewise, we cannot ignore that there are what is known as fireworks. These are the set of flames, sparks and fumes that are produced when rockets, firecrackers and all kinds of pyrotechnic devices are ignited that give rise to a beautiful show where lights, sound and color become the protagonists. At parties and shows of various kinds is where those take place.
Finally, it should be noted that it is known as a wildfire that burns something that was not intended to burn.
