very short summary of the chapter fire:friend and foe

Answer 1

Friends are those who inform you, yours fault
Foe- foes are those who can not say or inform you, yours fault, etc.

This is the difference between friends and foe.

Answer 2

A short summary of the chapter is as follows. Fire is a good servant but a very bad master. It is important for our everyday life but at the same time we should make sure that there is no accident due to it.

The particular temperature at which a fuel burns is known as the kindling temperature of the fuel or its "flash point". We can put out a fire in the following three ways.

(1) Take the fuel away

(2) Stop the oxygen supply

(3) Lower the temperature or remove the heat. A water spray will not be able to douse an oil fire.

As a matter of fact, it can be fatal. Water will get carried away with burnt oil and hence fire will spread. In the same way, for electric fires also water should not be used as it may create electric shocks.
