What is fire ? Write down the merits and demerits of fire? How fire is a bad master
but a good servant?
Answers
Answer:
to master – the useful resource of fire. Generating light and heat, fire has many uses and might provide more benefits to people today than at any other point in history. However, when not controlled, fire can cause great destruction and injury.
Long before gas and electricity were invented, people depended on fire for light and heat. With the wide range of light and heat-generating inventions available today, fire as a source of light and heat tends to be reserved to fireplaces, tiki torches, campsites and barbecue pits. Electricity is a cheaper resource than fuel for fire. Electricity is also easier to control.
Power for Homes and Industries
The electricity that powers our homes comes from power plants, most of which have fire at the core of production. Power plants use generators that utilize fire for processing. These power plants generate greater amounts of electricity than wind or solar-powered sources, but they also cause greater damage to the environment. Coal and other types of fossil fuels used for fire release pollutants when burned.
Benefits to the Environment
Fires occurring in nature can restore ecological balance and facilitate regeneration. Over time, forest floors become littered with debris and choked by heavy undergrowth that competes with trees for nutrients and water. Wildlife can even be displaced from its natural habitat. Low-intensity fires clear forest floors with minimal damage to the trees. Fires can also rid forests of insect infestations and potential diseases.
Today, low-intensity forest fires are often intentionally started to pre-empt larger and more destructive ones that may occur in fire-prone regions.
The Dangers and Damages of Fire
Fires require oxygen and fuel to be ignited. With oxygen present in the air, faulty electrical wiring, cigarette butts, static electricity, and even concentrated sunlight can act as fuel and a destructive fire can start. Fires are made more deadly by smoke and toxic gases emitted from consumed materials. According to the U.S. Fire Administration (part of FEMA), there were 1.3 million fires in 2015 that led to 3,280 deaths, 15,700 injuries and more than $14 billion in damages.uTypes of Industrial Pollutants

For nearly 200 years, American consumers have relied on industrial processes to create the products we use every day. From the smallest electronic devices to the largest vehicles, industrial methods of production have revolutionized modern life. Unfortunately, a major side effect of increased industrial production is pollution. Industrial pollution can affect the air we breathe, the water we drink, the ground we walk on and even the light we see and sounds we hear.
Answer:
Fire is the visible effect of the process of combustion – a special type of chemical reaction.

In a nutshell,
Fire removes low-growing underbrush, cleans the forest floor of debris, opens it up to sunlight, and nourishes the soil. Reducing this competition for nutrients allows established trees to grow stronger and healthier. History teaches us that hundreds of years ago forests had fewer, yet larger, healthier trees.
You must be careful to use fire wisely and under control so that it will not hurt you. Don't play with the candle flames. Fire is a good servant but a bad master. we learned how to build and extinguish fires safely, since fire is a good servant but a bad master.
Explanation:
Fire is a bad master because it has high temperature and it can burn any object. fire is a bad master because it can burn you.
