1. What is Combustion?
Combustion is a process in which a substance, burns in the presence of oxygen, or reacts with oxygen to produce heat and light. It is a chemical process.
2. What is meant by Calorific Value?
The calorific value of a substance is the amount of heat energy contained in it. When a certain amount of a substance undergoes complete combustion at a constant pressure, the amount of heat energy released determines the calorific value of the substance. The unit in which the calorific value is measured is kilo-joule per kilogram, KJkg-1.

7. What is the difference between Combustion And Flame?
The most basic difference between combustion and flame is that combustion refers to only heating without any flames because most of the energy gets converted to heat during burning, thereby leading to less light energy compared to flame. In case flames are created during the process of combustion, it is known as burning.
8. Why does paper burn with a yellow flame according to Chapter 6 of Class 8 Science?
An insufficient flow of oxygen while combusting this piece of paper leads to the production of solid carbon particles, which rise through the flame. These particles become hot, burn and ultimately give a yellowish light. That is why a piece of paper will usually burn with a yellow flame.
