Question 2
1 / -0

Which of these is the main constituent of petroleum gas?

A
Butane

B
Propane

C
Methane

D
Ethane

Solution

Petroleum gas is a mixture of ethane, propane and butane. Butane, being a major part of the composition is about 95%.
Question 3
1 / -0

What is the source of fly ash?

A
Petroleum

B
Natural gas

C
Coal

D
All of the above

Solution

Fly ash is a fine powder formed when large amount of coal is burnt in sufficient quantity of air in places like thermal power stations etc. The ash is carried by atmospheric air due to strong current of air in the furnace, Hence, this ash is called fly ash. It causes respiratory problems when inhaled by man..
Question 4
1 / -0

Which one of the following is NOT a fossil fuel?

A
Coal

B
Biogas

C
Petroleum

D
Natural gas

Solution

Biogas is formed by anaerobic degradation (fermentation) of plants and animal wastes. Hence, it is not a fossil fuel.
Question 5
1 / -0

Study the characteristics given below:

It is a tough, porous and black substance.
It is a pure form of carbon.

Based on the above characteristics, identify it from the following.

A
Kerosene

B
Petrol

C
Coke

D
Lubricating oil

Solution

Coke is a tough, porous, black substance. It is almost a pure form of carbon and used in the manufacture of steel.
Question 6
1 / -0

Which of the following statements is true about petroleum?

A
Lighter than water and soluble in it.

B
Heavier than water and insoluble in it.

C
Lighter than water and insoluble in it.

D
Heavier than water and soluble in it.

Solution

Petroleum has less density than water so it floats on water. It is insoluble in water because petroleum is non-polar while water is polar.
Question 7
1 / -0

Which of the following properties is NOT a characteristic of a good fuel?

A
High ignition temperature

B
Low cost

C
Causes minimum pollution

D
Readily available

Solution

Fuel is said to be good if it has the following characteristics: (i) Low ignition temperature. (ii) Low cost. (iii) Causing minimum pollution on burning. (iv) Readily available.
Question 8
1 / -0

Why is producer gas not a good fuel?

A
It contains CO which is poisonous.

B
It contains CO₂which is abundant.

C
It contains CO₂which does not burn.

D
It contains N₂ which does not burn.

Solution

Producer gas is not a good fuel because it contains nitrogen which does not burn.
Question 9
1 / -0

Which of the following is most harmful for the human body?

A
CO

B
CO₂

C
Oxides of nitrogen

D
Lead compounds

Solution

Carbon monoxide is the most harmful substance for the human body.
Question 10
1 / -0

What are the characteristics of a rocket fuel?

A
Light and compact

B
High calorific value

C
Burns rapidly

D
All of the above

Solution

A fuel should have the following characteristics to act as a rocket fuel: (i) It should be light and compact. (ii) It should produce high energy on burning.
Question 11
1 / -0

Which of the following is formed during the process of anaerobic fermentation?

A
Biogas

B
Natural gas

C
Water gas

D
Petroleum

Solution

Biogas is produced by the decomposition of animal dung, domestic and agricultural waste in the presence of anaerobic bacteria. It contains methane in bulk (50 - 68 %) and other gases in relatively low proportions i.e. CO₂(25−35 etc.
Question 12
1 / -0

Which of the following has the highest boiling point?

A
Kerosene

B
Petrol

C
Diesel

D
Water

Solution

Water has the highest boiling point.
Question 13
1 / -0

A How is coke superior than coal as a fuel?

A
Coal is a mineral and burns releasing smoke while coke is a residue.

B
Coal is an impure form of carbon, while coke is a pure form of carbon.

C
Only coal consists of atoms of carbon, hydrogen, oxygen and sulphur while coke mainly consists of carbon.

D
All of the above

Solution

Coke is almost a pure form of carbon, it is a good fuel and burns without smoke. While coal is an impure form of carbon and burns releasing smoke.
Question 14
1 / -0

Which of the following is in descending order of the quality of coal?

A
Peat > bituminous > lignite > anthracite

B
Bituminous > peat > lignite > anthracite

C
Anthracite > bituminous > lignite > peat

D
Lignite > anthracite > bituminous > peat

Solution

Anthracite is by and far the most superior quality of coal which contains 94-98% carbon. It is lustrous. It burns without smoke and gives more heat and little ash. Hence, the grading of coal from superior to inferior is Anthracite, bituminous, lignite, peat.
Question 15
1 / -0

Which of the following is an example of a liquid fuel?

A
Paraffin wax

B
Coal gas

C
LP.G.

D
Alcohol

Solution

Fuels can be classified on the basis of their physical state like solid, liquid and gas. Alcohol is an example of liquid fuel.
