A
LPG

B
CNG

C
coal

D
bitumen

Solution

Compressed Natural Gas happens to be a very viable alternative to traditional fuels particularly for use in the automobile industry. Being low in pollutants, high in calorific value and heat yield, economical and available in abundance globally, CNG is the perfect alternative for most.

Secondly, CNG is environment friendly as it reduces vehicular exhaust emissions significantly. Carbon Monoxide emissions are reduced to a maximum of 90 per cent and Hydrocarbon emissions by 60 per cent as compared to vehicles that use Petrol. Carbon Dioxide emissions, a cause for global warming, are also reduced significantly by 10 per cent.
Hence, Use of Diesel and Petrol as fuel in automobiles is being replaced by CNG.
Question 3
1 / -0

CNG is:

A
highly polluting

B
less polluting

C
not at all polluting

D
none of these

Solution

Correct Answer: Option B

Which among the following is considered as the cleanest fuel?

A
Cow dung cake

B
Petrol

C
Kerosene

D
LPG
Solution
Liquefied Petroleum Gas is considered as cleanest fuel because of the following reasons:
1. LPG has a high calorific value. The calorific value of LPG is about 50 KJ/g.
2. It is very neat and clean domestic fuel. LPG burns with a blue smokeless flame and leaves no ash behind. So, it does not cause any pollution. Therefore, LPG is a clean fuel.
3. It does not produce any poisonous gases on combustion.
4. LPG is easy to handle and convenient to store.
5. LPG is easy to handle and can be ignited almost instantaneously.

A
Coke

B
Coal tar

C
Coal gas

D
CNG

Solution

CNG is made by compressing natural gas which is mainly composed of methane, to less than 1 percent of the volume it occupies at standard atmospheric pressure. It is stored and distributed in hard containers at a pressure of 20–25 MPa, usually in cylindrical or spherical shapes.
Question 6
1 / -0

What are the benefits of using compost?

A
It saves the land from harmful effects of chemical fertilisers

B
Civic authorities are benefited too as they have to dispose off a reduced quantity of waste

Question 7
1 / -0

Which of the following can be adopted for saving cooking gas?
1. Using a pressure cooker instead of an open vessel
2. Keeping rice, dal etc. in water soaked condition for some time before cooking

A
1 and 2

B
2 and 3

C
1 and 3

D
1, 2 and 3
