Question
Explain with an example how can you put out fire by cutting the supply of oxygen.
Answer

Oxygen is one of the three elements essential for causing fire. If we can disrupt the supply of oxygen then we can put of the fire.
This can be applied in case of small fires. If we throw a damp blanket or a sack over the fire, it cuts off the supply of oxygen and the fire is immediately put off.
