Carbon and Fossil Fuels Questions

Multiple choice evs how to save fuel define fossil fuels conservation of fuels reason for finishing of materials (resources)

Which of these is not a fossil fuel?

  1. Coal

  2. LPG

  3. Bio gas

  4. All are fossil fuel
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

LPG is a fossil fuel which contains low carbon. It is a fossil fuel that does not occur during isolation. LPG is found naturally in combination with other hydrocarbons, crude oil, and natural gas. LPG is produced during natural gas processing and oil refining process.

Coal and Natural gas are also the fossil fuels and are obtained from earth crust.

Biogas is a mixture of methane ,carbon dioxide ,hydrogen and hydrogen sulphide. it is produced by anaerobic degradation of animal waste such as cow dunk in presence of water.

Hence options C  is correct.

Depletion of petrol can be controlled by:

  1. using CNG

  2. using LPG

  3. using kerosene

  4. none of above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Petrol is a limited resource and can be exhausted if not used wisely. Natural gas is stored under high pressure as CNG. CNG can be used as a fuel instead of petrol as it is less polluting. It is a cleaner fuel.

Excessive burning of fossil fuels is a major cause of  Global Warming.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Excessive burning of fossil fuels is a major cause of "GLOBAL WARMING".

Explanation :
Carbon dioxide (CO2), which, while not  the most potent greenhouse gas, 

is nevertheless the main driver of the greenhouse effect. When fossil fuels - coal, oil and natural gas - are burnt they release CO2 into the atmosphere. Because of this, the layer of greenhouse gas is getting thicker, which is, in turn, making the Earth warmer. Thus the ongoing unlimited burning of fossil fuels is the cause of climate change and global warming.

The gas which is produced from vegetation and animal residue is called ______________.

  1. natural gas

  2. bio gas

  3. bio chemical gas

  4. none of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Shrubs, farm waste, animal and human waste are used to produce biogas for domestic consumption in rural areas.The biogas plants using cattle dung are known as ‘Gobar gas plants’ in rural India. These provide twin benefits to the farmer in the form of energy and improved quality of manure.
