2. (a) What are Some Common Uses of Fire?

Ans: Some common uses of fire are to cook food, generate electricity and keep our houses warm during the winters.

(b) In What Sense is It a “Bad Master”?

When a fire gets out of control, it becomes the “bad master”. It becomes dangerous and burns everything that comes into contact with it and causes the destruction of life and property.

Ans:

(i) Fuel – coal, cooking gas, wood

(ii) Oxygen – air

(iii) Heat – smouldering paper, lighted matchstick, burning coal.

4. What are the Three Main Ways in Which a Fire Can Be Controlled or Put Out?

Ans: A fire can be put out by removing one of the three things which are responsible for its cause.

(i) Ceasing the oxygen supply. If oxygen doesn’t reach the fire, it will    immediately stop.

(ii) Removing the fuel, as burning cannot take place without the fuel. 

(iii) Bringing the fuel’s temperature below its ‘flash point’.

5. Match the items in Box A with those in Box B.

Ans:

6. Why Does a Burning Candle Go Out When You Blow on It?

Ans: When a candle is blown out, the hot air around the candle gets replaced by the cold air. The cold air then lowers the temperature of the candle below the flashpoint. As we know that no fuel burns below its flash point, so the candle goes out. 

7. Spraying Water is Not a Good Way of Putting Out an Oil Fire or an Electric Fire. Why Not?

Ans: Spraying water onto an oil fire could be dangerous. When water is sprayed on an oil fire, the oil separates from the water and floats on the surface and hence continues to burn. The water flows quickly and carries the burning oil with it which further spreads the fire. In an electrical fire case, when the water is sprayed, it conducts an electric current and the person might get an electric shock and get severely injured.

8. What are the Three Main Ways in Which a Fire Can Be Controlled or Put Out?

Ans: Some things that we should do to prevent fire at home or school are:

(i) Inflammable substances must be handled with care. 

(ii) To prevent fire due to short circuits, the fuse should be scrutinized regularly and overloaded wires should be replaced with new wires.

(iii) Inflammable substances like petrol and kerosene should not be stored in schools or at home. People should be made aware of storing fuel and their flashpoints. 

(iv) Fire extinguishers must be installed and people should be taught about how they should be used in the hour of need.

(v) Contact numbers of the fire brigade and police should be kept on the speed dial in case of any emergency.

(vi) Any kind of fire should not be taken lightly and should be prevented before it spreads.
