Let’s Summarise NCERT Solutions For Class 7 English Honeycomb Chapter 8 Fire Friend and Foe

NCERT Solutions For Class 7 English Honeycomb Chapter 8 Fire Friend and Foe, Our ancestors were already aware of lightning and volcanoes before they knew about the fire, hence, the fire was dangerous, powerful, frightening and a miraculous mystery for them. But science has informed modern men that it is only a result of a chemical reaction.

FIRE

O₂ + CO₂ + H₂ ==> HEAT + Light

When oxygen present in the air combines with carbon and hydrogen present in the fuel, energy is released in form of heat and light and this is FIRE. Requirements for making fire are – fuel, heat, and oxygen. Fuel and oxygen are easily available to us in the form of wood, oil, and gas, and from air respectively. But providing the heat to an object to make it catch fire is the tricky part. Every fuel burns at a particular temperature which is ‘flashpoint’ or ‘kindling temperature’.

Fire will be a good servant if you handle it with care but it can be a cruel master if it goes out of control.

Fire – Our Friend	Fire – Our Foe
It is used in our house daily for cooking food, burning candles, warming our houses, producing electricity.	It can cause damage to life, houses, and even forests.

You can control fire by deducting any one of its three requirements.

• It can be stopped by taking away the fuel.
• It can be minimised by cancelling the oxygen supply. For eg, blankets are thrown over burning objects.

• You can control fire by reducing the flashpoint. For eg, spraying water cools down the temperature and the fire, eventually, stops.

However, you cannot use water to put out –

• Electrical fires because a person might get a shock as water is a good conductor of electricity.
• Oil fires as oil is lighter than water and it will float above it, this may even cause rapid spread of fire as water flows quickly.

One must reside in using fire extinguishers in these cases.

Gone are the days when people used to form human chains and pass buckets of water from ponds and wells to the fire hazard. Now – a – days, there are trained and skillful firefighters to handle this. The trained team of firefighters is the fire brigade. They take training to handle all kinds of fire. They learn first-aid as well to deliver an immediate remedy to people suffering from burn injuries.

Fire is a dear friend if it can be used properly, but can turn dangerous if it goes out of control. None the less, fire is worshipped as God in many cultures around the globe.
