Lignite is a 

  1. Gaseous fossil fuel

  2. Liquid fossil fuel

  3. Solid fossil fuel

  4. Inorganic mineral
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Lignite, also known as brown coal, is a combustible sedimentary rock which is formed from naturally compressed peat. It has a low heat content and used as a fuel to generate energy. Since, it is non-renewable source of energy, it is considered as a fossil fuel and because it's a rock, so it is a solid fossil fuel.
So, the correct answer is 'Solid fossil fuel'.

Green fuel is:-

  1. Leaded petrol

  2. Unleaded petrol

  3. Gasohol

  4. Low sulphur diesel
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Green fuel, also known as Green Petrol, is a type of fuel distilled from plants and animal materials, believed by some to be more environmentally friendly than the widely-used fossil fuels that power most of the world. It contains low amount of sulphur. So the above selected option is correct

Petrol is known as gasoline in

  1. U.S.A.

  2. U.K.

  3. Parts of India

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Petrol is short term for "refined petroleum or distillate petroleum" In American English, it is called "Gasoline" which is commonly shortened for"gas". It has become popular as the trade name of petrol in the U.S. While UK and India or its part thereof it is called petrol ( British English). 

Hence, the correct answer is 'U.S.A'

Which of the following is a fossil fuel?

  1. Petroleum

  2. Wood

  3. Cow dung

  4. Dry leaves
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Fossil fuel is a general term for buried combustible geologic deposits of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, natural gas or heavy oils by exposure to heat and pressure in the Earth's crust over hundreds of millions of years.

For example- petroleum, coal, etc.

What can we observe if petrol gets finished ?

  1. Less vehicles on roads

  2. Less trees around us

  3. Less water around us

  4. More vehicles on roads.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

If petrol is not there for use, we will be using alternative methods like CNG etc , but they are also limited . So there will be decrease in vehicle use.

So, the correct answer is 'less vehicles on the road'

Biodiesel is obtained from

  1. Jatropha

  2. Cedrus

  3. Eicchornia

  4. Opuntia
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Biodiesel refers to a vegetable oil or animal fat-based diesel fuel consisting of long-chain alkyl (methyl, ethyl or propyl) esters. Biodiesel is typically made by chemically reacting lipids with an alcohol producing fatty acid esters.

Jatropha oil is produced from the seeds of the Jatropha curcas, a plant that can grow in wastelands across India, and the oil is considered to be an excellent source of bio-diesel. India is keen on reducing its dependence on coal and petroleum to meet its increasing energy demand and encouraging Jatropha cultivation is a crucial component of its energy policy
Large plots of waste land have been selected for Jatropha cultivation and will provide much needed employment to the rural poor of India. Businesses are also seeing the planting of Jatropha as a good business opportunity.

Thus, the correct answer is option A.

Which one of the following can be used in place of petrol?

  1. Ethanol

  2. Butanol

  3. Propanol

  4. Methanol
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Over the last few years more and more alternatives for petrol have been sought. As oil reserves run out, petrol prices rise and the climate continues to change, people are increasingly looking towards ethanol fuel as a potential solution to all of these problems.
Ethanol is more commonly known as the alcohol found in alcoholic drinks. It is a colourless and flammable liquid (at room temperature and pressure); it is its flammable nature that makes it useful as a fuel.
The two main sources for ethanol fuel are either sugar beet which can by fermented directly, or from cereal grains. In the later case the starch must first be broken down into sugars, this is accomplished (for fuels) by treating it with dilute sulphuric acid.
Thus, the correct answer is option A.

Natural gas that was formed from ancient prehistoric forests is called

  1. Fossil fuels

  2. Petroleum

  3. Gobar gas

  4. LPG
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Fossil fuels are energy sources formed from the remains of ancient plants and animals buried under high pressure and temperature over millions of years. Petroleum is a specific type of fossil fuel, not the general term for all such materials.

Fossil fuels are 

  1. Conventional resources

  2. Non-conventional resources

  3. Non-renewable resources

  4. Both A and C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

  • Conventional sources of energy are generally non-renewable sources of energy as the accumulation or creation of conventional sources of energy takes years, once they are exploited or consumed. 
  • Fossil fuels are an example of conventional resources. Petrol, diesel, coal, natural gas, etc are examples of fossil fuels that are obtained by the microbial action on the dead matter for a long time. 
  • They are used as a source of fuel and energy from ancient times and it takes years to form once they are exploited.

Thus, the correct answer is option D.
