Answer 2

Answer:   3. The amount of oxygen available to support burning increases.

Chullah fire or a camp fire burns brighter when it is fanned;

This is because oxygen is the most important element which helps in burning. So during the process of fanning more amount of oxygen comes in, which may result in more fire. So as the amount of oxygen increases, fire produced will also increase.
