Carbon and Fossil Fuels Questions

Multiple choice commercial applications water and air and their importance natural resources and their types promotion of renewable resources protecting our environment

Which of the following is / are fossil fuels ?

  1. Coal

  2. Petroleum

  3. Natural gas

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

They all are fuels because they release heat energy when they are burned. They are fossil fuels because  they were formed from the remains of living organisms millions of years ago.

Energy source which do not evolve $CO _{2}$


  1. Oil

  2. Coke

  3. Nuclear energy

  4. Other organic substance
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The processes for which any CO2 is not evolved is :

  • all the forms of nuclear energy,
  • hydroelectricity (though dam reservoirs in the tropics might free a little methane, which is a greenhouse gas, because of the decaying of biological debris in the water),
  • sun rays,
  • wind,
  • tidal energy,
  • geothermal energy,
  • biomass if replanted.
  • So the correct option is C.

Multiple choice zoology meaning of life energy flow and loss energy flow in a food chain energy flows

Select correct answers :
(1) Flow of energy
(2) Flow of materials
(3) Flow information
(4) Flow of smoke

  1. 1, 2, 3 correct

  2. 1 and 2 correct

  3. 2 and 4 correct

  4. 1 and 3 correct
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Ecosystems are characterized by the flow of energy, the cycling of materials (nutrients), and the flow of information (e.g., biological signals). Smoke is not a standard component of ecosystem functional flow.

Which of the following is a non-polluting fuel used in vehicles ____________.

  1. Petrol

  2. Diesel

  3. LPG

  4. Kerosene
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

LPG (Liquefied Petroleum Gas) is considered a cleaner fuel compared to petrol or diesel, as it produces significantly fewer pollutants when burned in vehicle engines.

Multiple choice biology pictorial feature of plant kingdom uses of bryophytes introduction to bryophytes cryptogams

Peat is used at a fuel in some countries. Remains of which plant give rise to peat?

  1. Moss

  2. Ferns

  3. Angiosperms

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

Peat, also known as turf, is an accumulation of partially decayed vegetaation or organic matter.Sphagnum "moss", also called peat moss, is one of the most common components in peat, although many other plants can contribute.

So, the correct option is A. (moss)

Multiple choice biology pictorial feature of plant kingdom uses of bryophytes introduction to bryophytes cryptogams

Peat, obtained from Sphagnum moss, is used as ______________.

  1. Fuel

  2. Manure

  3. Corrosive

  4. Both (a) and (b)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Peat consists of deposits of vegetable matter which have accumulated in bogs and swamps and slowly decomposed, becoming somewhat carbonised and compacted. It is dark brown in colour. Peat is built by Sphagnum moss, for this reason, Sphagnum is called peat moss. Peat is used as fuel and manure.

So the correct option is D.

Which one contains hydrocarbons similar to those of petroleum?

  1. Tannin

  2. Starch

  3. Latex

  4. Resin
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Latex, particularly from plants like Hevea brasiliensis and certain members of Euphorbiaceae and Asclepiadaceae, contains complex hydrocarbon chains similar to petroleum hydrocarbons, which has sparked interest in petrocrops.

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'.

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.
