Weekly Quiz Competition

Question 1
1 / -0

Assertion: Fuel oil is better than coal for use in industries.
Reason: It has a high calorific value than coal and does not leave smoke or ash on burning.

A
Both Assertion and Reason are true. Reason is the correct explanation of Assertion.

B
Both Assertion and Reason are true. Reason is not the correct explanation of Assertion.

C
Assertion is true and Reason is false

D
Both Assertion and Reason are false.

Solution

Petroleum produces less $$CO_2$$ emission than coal during production. It produces less $$CO_2$$ than oil and coal. It is easily transported via pipelines, which reduces fuel cost for transportation.
Hence the correct option is $$A$$.
Question 2
1 / -0

When an oil well is drilled through rocks, what comes out first?

A
Petroleum

B
Natural gas

C
Crude oil

D
Residual oil

Solution

When a well is drilled through the rock, petroleum comes out first.
Hence, option B is correct.
Question 3
1 / -0

Which property of coke makes it useful in the manufacture of steel?

A
It generates intense heat but little smoke

B
It used as reducing agent

C
Both A and B

D
None of these

Solution

Coke is used as a fuel and a reducing agent in melting iron ore. It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel.
Question 4
1 / -0

Natural gas occurs:

A
above the petroleum oil

B
below the petroleum oil

C
above sea level

D
None of these

Solution

Petroleum occurs deep down under the earth between two layers of impervious rocks. Oil deposit are usually found mixed with water, sand and salts. Natural gas occurs above the petroleum oil trapped under the rocks.
Thus option $$\text{A}$$ is correct.
Question 5
1 / -0

Compared to oil, an advantage of using natural gas is that it:

A
prevents respiratory problems

B
prevents headaches

C
causes less air pollution

D
prevents over combustion

Solution

Natural gas tops other fossil fuels when it comes to clean burning. Since the process of natural gas combustion is almost up to the mark, the level of byproducts disseminated to the environment is little. In addition, advances in technologies have massively reduced nitrogen oxide, a common pollutant emitted by natural gas. The blue flame witnessed during the process of burning natural gas is an indication that the gas is burning perfectly.
Question 6
1 / -0

Which component of petroleum has a boiling point greater then $$350^{\circ}C$$?

A
Kerosene oil

B
Lubricating oil

C
Diesel oil

D
Petroleum gas

Solution

Lubricating oil boils at temperature greater than $$350^{0}C$$. So the correct option is D.
Question 7
1 / -0

Petroleum oil is found:

A
deep underground (sea beds)

B
in mountains

C
in glacier

D
in river

Solution

Petroleum oil is found deep underground in seabeds.
Question 8
1 / -0

Naphthalene balls are obtained from coal tar and are used as

A
mosquito repellant

B
moth repellant

C
honey bee repellant

D
snake repellant

Solution

$$\text{Naphthalene balls are used as moth repellents.}$$ Naphthalene balls are solids that turn into toxic gas. The toxic gas kills insects and may repel animals
Question 9
1 / -0

Though a few (gas-based) industries have been established, good reserves of natural gas in India remain unutilized. These vast resources of natural gas can be used in the production of :

A
Graphite

B
Carbide

C
Fertilizers

D
Synthetic petroleum
Question 10
1 / -0

The dead aquatic organisms that were buried under the sand and clay of the sea bed, were converted to petroleum owing to:

A
absence of air

B
high temperature

C
high pressure

D
all of the above

Solution

The dead aquatic organisms that were buried under the sand and clay of the seabed, were converted to petroleum owing to the absence of air, high temperature, and high pressure.
High temperature: The organic material is compressed between Earth’s mantle, with very high temperatures, and millions of tons of rock and sediment above.
Absence of air: Oxygen is completely absent in these conditions, and the organic matter begins to transform into a waxy substance named kerogen.
High pressure: With more heat, time, and pressure, the kerogen undergoes a process called catagenesis, and transforms into hydrocarbons. In this way, Petroleum is formed.
Hence, option D is correct.
