Carbon and Fossil Fuels Questions

Multiple choice commercial applications bioenergy biofuels making biofuels technological and industrial development

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.

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.

Which of the following is/are measures taken for protection of fossil fuel?

  1. Gasification of coal

  2. CNG

  3. Gasohol

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

Gasification of coal, use of CNG, and use of gasohol are all methods to either extend the life of fossil fuel reserves or reduce the environmental impact of their consumption, thus serving as measures for their protection or sustainable use.

LPG cooking gas is

  1. Low pressure gas

  2. Biogas

  3. Fossil fuel

  4. Low price gas
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Liquefied petroleum gas or liquid petroleum gas (LPG or LP gas), also referred to as simply propane or butane are flammable mixtures of hydrocarbon gases used as fuel in heating appliances, cooking equipment and vehicles. 

LPG is prepared by refining petroleum or "wet" natural gas and is almost entirely derived from fossil fuel sources, being manufactured during the refining of petroleum (crude oil) or extracted from petroleum or natural gas streams as they emerge from the ground. Thus, the correct answer is option C.

Jatropha is used for the production of biodiesel because

  1. It can be easily grown under harsh condition

  2. It is a non-edible oil

  3. It is volatile

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

Biodiesel is produced from jatropha oil. Jatropha is used because it is not edible therefore, it will not create problems for humans in terms of food shortage. It also has the ability to withstand drought, naturally, repel pests, and grow in subprime soil and combat soil erosion. Thus, the correct answer is option D.

Which of the following is fossilized remains of organic materials?

  1. Natural gas

  2. Petrol

  3. Gold

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
A fossil is the remains of a once-living plant or animal that was preserved in rocks or other materials. It includes fossil fuels (oil, coal, petroleum, and natural gas) that have been formed from the remains of these dead plants and animals.It includes bones or shells of animals and leaves, seeds, or woody parts of plants. Which are subjected to tremendous pressure, heat and other conditions that convert them into fossil fuels.
So, the correct answer is 'Both A and B'
