Fire: Friend & Foe Summary Class 7 English Honeycomb

SUMMARY OF THE LESSON 

Fire is a necessary evil. It is a boon as well as a curse. It has made our life comfortable, but we cannot touch it. It was the first great invention made by early man. 

Early man didn't know how to make fire. But he must have seen the destructive power of fire. He must have watched lightning and volcanoes. He was afraid of it. What is fire? Fire is, in fact, the result of a chemical reaction. The air has oxygen, while fuels have carbon and hydrogen. When the two combine, energy is released in the form of heat and light. This is what we call fire. 

Three things are needed to make fire-fuel, oxygen and heat. The common fuels are wood, coal, gas and petrol. Oxygen comes from the air. That is why, when we blow on burning paper, it bursts into flame. Fuel and oxygen do not make fire themselves. They need heat. A lighted match provides that heat. Every fuel begins to burn at a particular temperature. 

Fire is a good servant but a bad master. It is useful as long as it is under control. The moment it becomes out of control, it spreads havoc. Every year thousands of homes and trees are damaged by fire. Forest fire destroys trees and kills people

Fire can be put out in three ways. We can take away the fuel, or stop oxygen from reaching the burning material. The third way is to bring down the temperature below the flash point. Remove the hot air around the burning candle, and it will go out. Water also lowers the temperature and puts out the fire. 

Some fires cannot be put out with water. Oil fire is one such example. The oil floats to the top of water and continues to burn as well as spread. Electrical fire also can't be controlled with water. It is fought by using carbon dioxide. 

On the whole, we have learnt well to control fire and make good use of it in everyday life. Long ago there were no firemen. The people used to bring and throw bucketfuls of water on the flames. Now there are laws to stall fire extinguishers in every big building. There are fire brigades in every town. Trained fire fighters use their skills like cutting off power supply, pulling down weak walls and spraying water to bring fire under control. They are also trained to provide first aid to injured people. 

Fire is still worshipped in many parts of the world. It helped early man to keep off animals and settle down in safe places.

FAQs on Fire: Friend & Foe Summary Class 7 English Honeycomb

1. What are the different ways in which fire can be a friend?
Ans. Fire can be a friend in several ways. It provides heat, which is essential for cooking food, keeping us warm, and generating electricity. Fire is also used in industries for various purposes like melting metals, producing energy, and manufacturing goods. Additionally, fire plays a crucial role in the natural ecosystem by promoting the growth of certain plants and trees.
2. How does fire act as a foe?
Ans. Fire can act as a foe in numerous ways. Uncontrolled fire can cause destruction, leading to loss of lives, property, and forests. It can spread rapidly and cause accidents, such as building fires and forest fires. Fires can also release harmful gases and pollutants, contributing to air pollution and negatively impacting the environment. Moreover, accidental fires can result in injuries or even death.
3. What safety measures can be taken to prevent fire accidents?
Ans. To prevent fire accidents, several safety measures can be taken. It is important to install smoke detectors and fire alarms in homes and buildings to detect fires at an early stage. Regularly checking and maintaining electrical connections and appliances is crucial. Proper storage and handling of flammable substances, like gasoline and chemicals, should be ensured. Educating people about fire safety, conducting fire drills, and having fire extinguishers readily available are also effective preventive measures.
4. How does fire promote the growth of certain plants and trees?
Ans. Fire promotes the growth of certain plants and trees through a process called fire ecology. Some plants have adapted to fire-prone environments and have developed features that allow them to survive and even thrive after a fire. The heat from the fire helps in the germination of their seeds, and the removal of thick vegetation by fire allows sunlight to reach the forest floor, stimulating the growth of new plants. Additionally, fire can control the growth of competing plant species and help maintain a healthy ecosystem.
5. Can fire be beneficial for agriculture?
Ans. Yes, fire can be beneficial for agriculture if used in a controlled manner. Controlled burning, also known as prescribed burning, is a technique used in agriculture to improve soil fertility and remove unwanted plant material. It helps in the recycling of nutrients, control of pests and diseases, and reduction of weed growth. However, it is important to follow proper guidelines and safety protocols while using fire in agriculture to prevent accidental fires and minimize the negative impacts on the environment.
