Question 1
1 / -0

The density of coal is _______ when compared to coke.

A
more

B
less

C
same

D
can't say anything

Solution

Coal is a naturally available substance whereas Coke is prepared substance with some impurities and high Carbon content, usually made from Coal.While Coal is Solid mass in physical appearance, Coke is Porous ( it means that it has large surface area ).
So the density of coal is more than the coke as coke is porous which has large surface area.
Hence option A is correct.
Question 2
1 / -0

List I List II
A Kerosene I Metalling of roads
B Diesel II Jet aircraft fuel
C Paraffin Wax III Generation of electricty
D Bitumen IV Lubricants

A
(A)-I, (B)-II, (C)-III, (D)-IV

B
(A)-I, (B)-III, (C)-IV, (D)-II

C
(A)-II, (B)-III, (C)-IV, (D)-I

D
(A)-IV, (B)-II, (C)-III, (D)-I4
Solution
- Kerosene is used in jet aircraft as fuel.
- Diesel is used in the generation of electricity.
- Paraffin wax is used as a lubricant.
- Bitumen is used for metalling of roads.
Hence, option $$C$$ is correct.
Question 3
1 / -0

LPG is ___________.

A
Liquefied petroleum gas

B
Low petroleum gas

C
Liquid pressure gas

D
None of these

Solution

LPG is short for liquefied petroleum gas. It is used as a fuel in industries and homes.
Hence, option $$A$$ is correct.
Question 4
1 / -0

Which amongst the following is not free state of carbon?

A
Diamond

B
Graphite

C
Coke

D
Petrol

Solution

Diamond, graphite, and coke exist in the free state of carbon whereas petroleum is the mixture of hydrocarbons where carbon and hydrogen are present. So the substance which is not available in a free state is petrol.
Hence, option D is correct.
Question 5
1 / -0

Coke is used in the preparation of :

A
Water gas

B
Producer gas

C
Graphite artificially

D
All of the above

Solution

Coke is used in the preparation of water gas ($$CO+H_2$$), producer gas ($$CO+N_2$$) and graphite by artificial methods.
$$C+H_2O\longrightarrow CO+H_2$$ ..... (water gas)
$$C+air\longrightarrow CO+N_2$$. ..... (producer gas)
Hence, option $$D$$ is correct.
Question 6
1 / -0

__________ is widely used as fuel in factories and thermal power stations.

A
Petroleum

B
LPG

C
Coal

D
CNG

Solution

Coal is widely used as a fuel in coal-based industries due to its advantages as its high calorific value. It releases less amount of smoke after burning. So, coal is a widely used fuel in factories and thermal power stations.

Hence, option C is correct.
Question 7
1 / -0

Which of the following is an example of an inexhaustible resource?

A
Crude oil

B
Groundwater

C
Coal

D
None of these

Solution

Renewable resources are those which get renewed or replenished. Groundwater can be replenished when it rains and the rainwater percolates into the soil and collects underground. Crude oil and coal are non-renewable sources.
Question 8
1 / -0

Coal and petroleum are called ________.

A
Fossil fuels

B
Renewable energy

C
Green energy

D
Natural fuels

Solution

Coal and petroleum are called fossil fuels. They serve as source of energy as on combustion, they release heat energy.
Question 9
1 / -0

Process used in purification of water is:

A
carbonation

B
carboxylation

C
carbonisation

D
chlorination

Solution

Chlorination of water is done during purification of water to kill bacteria, viruses and other microbes in water.
Question 10
1 / -0

Select the correct alternative(s).
Coal is a fossil fuel and it cannot be prepared in a laboratory or industry because the formation of coal:
(A) is a very slow process.
(B) needs very low pressure and low temperature
(C) needs very high pressure and high temperature.
(D) causes air pollution

A
A and B

B
B and D

C
C and A

D
D and A

Solution

Coal is a fossil fuel formed from dead plant matter that got buried deep inside layers of soil. The formation of coal involves various biological and geological processes which occur at very high temperature and pressure over a long period of time. But the formation of coal doesn't cause any air pollution.
Only statements A and C are correct

Hence option $$c$$ is correct.
