Explain About Fire? ;
A fire is a sudden chemical reaction that releases heat and light. When fuels, such as wood, gasoline, or coal, are heated, the atoms within them start to move around faster. At a certain temperature, the atoms start to break free from the fuel and mix with the oxygen in the air. When the atoms combine with oxygen, they create heat, light, water vapor, and carbon dioxide.
Source of Fire and Uses of Fire By Early Man
Fire was used by early man for a variety of purposes. It was used to provide warmth, to cook food, to provide light, and to ward off predators. It was also used as a weapon to kill prey or to intimidate enemies.
Uses of Fire
The use of fire is vast. It is used for cooking, providing warmth, providing light, signaling danger, and destroying unwanted things.
Fire Manufacturing
The fire manufacturing process begins with the selection of a fuel. The fuel is then heated until it begins to break down. The heat is then increased to the point where the fuel starts to release gas. The gas is then ignited, and the fire is born.
Types of Combustion
There are three types of combustion: complete, incomplete, and external.
In complete combustion, all the fuel is completely burned, and the products of combustion are water vapor and carbon dioxide.
In incomplete combustion, some of the fuel is not burned, and the products of combustion are carbon monoxide and other pollutants.
In external combustion, the fuel is burned outside the engine, and the products of combustion are transferred into the engine.
Incomplete Combustion
Incomplete combustion is a type of combustion that is not complete. This means that not all of the fuel is burned, and some of it is left in the form of pollutants. These pollutants can cause problems with air quality and public health.
