What is Fire?
Fire is a chemical process that produces heat and light. It is a rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. At a certain point in the combustion reaction, called the ignition point, flames are produced. The flame is the visible portion of the fire.
There are three elements that are necessary for a fire to start and continue to burn: heat, oxygen, and fuel. If any one of these elements is removed, the fire will go out.
What is Combustion? and Types of Combustion – NCERT Class-8 Notes
Combustion is a chemical process that involves the rapid reaction of a substance with oxygen, releasing heat and light. The substance that reacts is called the fuel, and the source of oxygen is called the oxidizer. The fuel can be a solid, liquid, or gas, but it is usually a liquid or gas. The oxidizer is usually atmospheric oxygen, but it can also be other substances, such as hydrogen peroxide or chlorine.
In this article, we will look into the meaning of combustion, how we control fire, and types of combustion in detail. These are important concepts of NCERT Class 8 Science. Students can go through this article to get comprehensive notes on combustion and its types, and how we control fire.
