What is combustion?

Combustion is a chemical process which involves the reaction of a substance with oxygen in order to give away heat. The substance that undergoes combustion is known as fuel. Fuels can be

  1. Solid

  2. Liquid

  3. Gas

In NCERT Science Class 8 Chapter 6 you will majorly learn about these fuels and the process of combustion. On the basis of combustion, materials can be divided into two types

  1. Combustible materials

  2. Non- combustible materials

While studying  NCERT science Chapter 6 you will also get to know what are combustible and non-combustible materials.

What is the ignition temperature?

Have ever these questions crossed your mind

  1. Why LPG burns so fast while CNG takes some time?

  2. Why kerosene is required to burn wood?  

The answers to these above-stated questions lie in their ignition temperatures.  It refers to the minimum temperature at which a substance catches fire. Now you can try attempting the above questions. As you will gradually go about the NCERT chapter 6 combustion and flame you will get familiar with the ignition temperature of various substances and how it is important for combustion.

Inflammable substances

Have you ever seen the sign given below on certain cans or cylinders? This sign refers that there is a highly inflammable substance in the cylinder and you must stay away from it. Inflammable substances are those substances which catch fire very easily.


So, what do you think can we say the ignition temperatures of inflammable substances are very low?  In NCERT  Class 8 Chapter 6 Combustion and flame we will talk about the different types of inflammable substances and what are the ways in which we can control fires caused by their burning?



This chapter also deals with flame and its structure. At the end of chapter 6 combustion and flame, you will get to learn about different types of fuels and their efficiency in causing combustion.
