Question 1
1 / -0

Which of the following statements is correct?

A
LPG is petroleum gas in liquid form.

B
LPG is liquefied methane.

C
LPG is liquefied propane.

D
LPG is a mixture of methane and ethane.

Solution

Liquefied Petroleum Gas (LPG) is actually petroleum gas in liquid form. When gas is compressed under pressure, it turns into a liquid. This makes it easy to store and transport the gas.
Question 2
1 / -0

When a well is drilled through the rock, ................ comes out first.

A
petroleum

B
natural gas

C
crude oil

D
residual oil

Solution

Refer to figure: It shows different resources present at different levels below the earth's crust
Question 3
1 / -0

LPG used as domestic fuel is mixed with a strong smelling volatile liquid for __________.

A
better combustion

B
good smell/fragrance

C
detection of gas leakage

D
higher calorific value

Solution

If the gas leaks in air, it can be easily detected due to smell and preventive measures can be taken. Hence, LPG is mixed with a strong smelling volatile liquid.
Question 4
1 / -0

Petroleum is:

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

$$\bf{Hint}$$: Like dissolves like - polar compounds are soluble in water.

$$\bf{Correct \ answer:}$$ Option $$C$$

$$\bf{Explanation}$$:
Petroleum is a naturally occurring liquid which consists of a complex mixture of hydrocarbons of various molecular weights, plus other organic compounds.
It is a highly volatile liquid form of hydrocarbon which is non-polar in nature.
As we know that water is a polar solvent in which only polar compounds are soluble, therefore Petroleum due to its non-polar nature is insoluble in water and it is lighter than water as it has less density and it is highly volatile in nature.
Question 5
1 / -0

Which of the following names represents the foul smelling, black, thick, viscous liquid obtained from destructive distillation of coal?

A
Coke

B
Coal tar

C
Coal gas

D
None of these

Solution

Coal gas is a flammable gaseous fuel made from coal and supplied to the user via a piped distribution system. Town gas is a more general term referring to manufactured gaseous fuels produced for sale to consumers and municipalities.
Coke is a fuel with few impurities and a high carbon content, usually made from coal. It is the solid carbonaceous material derived from destructive distillation of low-ash, low-sulphur bituminous coal. Cokes made from coal are grey, hard, and porous. While coke can be formed naturally, the commonly used form is man-made. The form is known as petroleum coke, or pet coke is derived from oil refinery coker units or other cracking processes.
Coal tar: a thick, oily liquid consisting mainly of hydrocarbons, produced by the destructive distillation of organic substances such as wood, coal, or peat. Coal tar is among the by-products when coal is carbonized to make coke or gasified to make coal gas.
Question 6
1 / -0

While leakage in L.P.G. gas cylinders, gas which gives fowl smell is:

A
Butane

B
Propane

C
Methane

D
Ethyl mercaptan

Solution

It is 'ethyl mercaptan' which is responsible for the pungent smell. Ethyl mercaptan is used as an additive to odorless gases like butane, propane, etc. to give foul smell which helps to identify the leakages in the L.P.G cylinders. - Ethyl mercaptan is an organic compound having molecular formula $$C_2H_5SH$$
Question 7
1 / -0

Which of the following is a fossil fuel?
1. Tar
2. Coal
3. Petroleum

A
$$1$$ only

B
$$1$$ and $$2$$ only

C
$$2$$ and $$3$$ only

D
$$1,2$$ and $$3$$

Solution

Coal and petroleum are fossil fuels. Tar is not a fossil fuel.

Fossil fuels are made from decomposing plants and animals. It is a natural fuel.

Tar is a black mixture of hydrocarbons and free carbon. It is obtained from several organic compounds during destructive distillation. Tar can also be produced from wood, coal, petroleum, or peat.

Hence, option $$C$$ is correct.
Question 8
1 / -0

Lead particles are released into the air by the burning of ___________.

A
coal in thermal power stations

B
petrol in automobiles

C
biomass in chullahs

D
LPG for cooking

Solution

Leaded petrol used to be a source of high levels of lead in the air of major cities. Significant reductions in the levels of airborne lead were achieved over recent years as the result of air pollution legislation introduced to remove lead from petrol.
Question 9
1 / -0

Which of the following is used as an anti -knocking compound?

A
TEL

B
$$C_2H_5OH$$

C
Glyoxal

D
Freon

Solution

An anti-knocking agent is the substance which is used to reduce the engine knocking. It increases the octane number of the fuel. It helps in auto-ignition by raising the temperature and pressure. TEL is tetraethyl Lead which is used as an Anti-Knocking compound.
Question 10
1 / -0

Match the following.
Column II Column II
1. Paraffin wax (p) Domestic fuel
2. Petrol (q) Used for manufacturing steel
3. LPG (r) Candles
4. Coke (s) Aviation Fuel

A

C
1 - (s); 2 - (r); 3 - (p); 4 - (q)

D
1 - (r); 2 - (s); 3 - (p); 4 - (q)

Solution

1. Paraffin wax is used to make candles.
2. Aviation fuel is a specialized type of petroleum-based fuel used to power aircraft.
3. LPG is the liquefied petroleum gas used as domestic fuel.
4. Coke is used to make steel.
