10 Lines on Fuels

Fuels play an important role in our daily life. From preparing food, to transportation and from electricity to rocket launch, fuels influence our life to a higher extent. Fuels release heat energy on burning or by undergoing chemical reactions which can be used by mankind for different purposes. The industrial revolution would not have been possible without the use of fuels.

The world would never have been the same if fuels were not discovered. Discovery of fire was the turning point for the human civilization which showed the way to new inventions.

Ten Lines on Fuels

Set 1

1) Fuels are the substances which release heat energy when burnt or undergo chemical reaction.

2) A fossil fuel is the fuel which has been formed by the natural process of the buried organism and vegetation.

3) Coal, petroleum products, natural gas are few forms of fossil fuels.

4) Wood was the first fuel used by the mankind.

5) Animal fat was also used as fuel in ancient times.

6) Fuels can be categorized as Solid, Liquid and Gaseous.

7) Coal, Wood, Peat, Dung cakes etc. are solid fuels and Petrol, Diesel, Kerosene etc. are liquid fuels.

8) Natural gas, LPG, Methane, CNG comes under gaseous fuels.

9) Nuclear fuels like Uranium are used for the fusion and fission reaction to generate nuclear energy.

10) Burning of fossil fuels release greenhouse gases eventually causing global warming.


Set 2

1) Fuels are the materials which are used to generate energy for various purposes.

2) Industrial revolution was never possible without the use of the fuels.

3) Fossil fuels like coal, petroleum, natural gas etc. are commonly used for cooking, transportation, power plants etc.

4) Uranium is the fuel used in nuclear reactors for generating nuclear energy.

5) Bio-gas or bio fuels are generated from the biomass, food and animal waste.

6) Too much usage of fuels leads to pollution and other ecological threats like global warming.

7) Fossil fuels are the non-renewable fuels which cannot be replenished and are on the verge of exhaustion.

8) Burning of fossil fuels produces more than 20 billion tons of carbon dioxide per year globally.

9) Renewable fuels are the fuels which are produced from the renewable resources. E.g. ethanol, methanol, hydrogen etc.

10) Fuels are the driving force of human civilization since its inception, and have helped the human race for its development but compromising natural ecosystem.


Set 3

1) Fuels are substances that combine with oxygen to produce a lot of heat.

2) 'Fuel' derives from the Sanskrit word ‘Indhan’ which means 'to burn'.

3) Electric energy is also used to obtain heat, so it is also sometimes included in fuels.

4) Fuels are classified into three groups as solid, liquid and gaseous fuels.

5) The thermal value of fuel is the amount of heat that is obtained after burning 1 gram of that fuel completely in the air.

6) Hydrogen has the highest thermal value i.e. 39.4 k/j per gram.

7) A fuel that has high defoliation rate is not considered appropriate for use.

8) The quality of good fuel is that the ignition temperature should be at least.

9) The fuels that have a higher calorific value are also called good fuels.

10) Compressed natural Gas is also an example of fuel that contains 80% - 90% of methane gas.

Set 4

1) The substances that produce light and heat when burnt are called fuels.

2) Solid fuels are in their solid form such as wood and coal, they produce heat when burnt.

3) Fluid fuels are made up of mixture of different kinds of hydrocarbons such as Kerosene, Petrol, Diesel, Alcohol etc.

4) Gaseous fuels like CNG and LPG also produce heat on burning and easy to transport and can be easily controlled.

5) Coal gas is produced by the distillation of coal and has 54% Hydrogen, 35% Methane, 11% Carbon Mono-Oxide, 5% Hydrocarbons and 3% Carbon Dioxide.

6) Natural gas is a good example of fuel that originates from oil wells and contains 95% hydrocarbons, which contains 80% Methane gas which is highly inflammable.

7) Flammable methane gas is also formed when wet dung rots, which burns easily in the presence of Oxygen.

8) The cheapest and easily available fuels are called good fuels and should have higher thermal value.

9) Hydrogen is used as rocket and in places where high heat generating flame is needed.

10) CNG is used as vehicle fuel and the first CNG station was set up at Nagapattanam in Tamilnadu.


Fuels play an important role in our daily life and without it we would not be able to get the basic requirement of life like food. But the over usage of the fuels have affected our environment on a larger extent leading to pollution and global warming.
