What is fire?
fire is a chemical reaction between a fuel and an oxidizer with release of energy in the form of light and heat.
For it to occur, 3 elements are required:
Prometheus. The titan friend of mortals, to whom he gave fire by stealing it from the gods
Fuel: Any substance capable of burning.oxidizing: It is the oxidizing component of the reaction, regularly it is the oxygen present in the air.Heat: It is the energy that is contributed so that the fuel and the oxidizer react in a certain time and space.
Additionally, a chain reaction is required, which is the factor that allows the reaction to progress and be maintained once it has started.
How Does Water Put It Out?
First water and fire they are, luckily, incompatible elementsotherwise it would have been very difficult to put out fires before the invention of fire extinguishers.
After knowing the factors that produce it: fuel, oxidizer (oxygen) and heat, it is easier to explain how water works in this task.
When a fire starts the heat of the combustion itself generates more combustionso that, as long as there is fuel and oxygen, it does not go out.
As water cannot burnis a natural extinguisher: when it comes into contact with the material, the water turns into water vapor, in whose gaseous state it absorbs a large amount of heat and cools the fire, until it prevents the fuel from continuing to react to the fire. .
Discover Why is Snow White?
Besides, when water moistens the fuel, it isolates it from the rest and prevent it from continuing to burn.
It is also for this reason that when an object is wet it is not possible to light itunless on top of the water there is some component that can function as fuel.
similarly another how to put out a small fire It is usually hitting some clothes, this works because for a short time it eliminates the oxygen present.
It is the same principle that those bells that are sold to extinguish a candle follow, obstructing the entry of air (with oxygen) around the burning.
