Concept explainers
(a)
Interpretation:
The boiling point range corresponding to the petroleum fraction containing the hydrocarbons that gives fuel in a car has to be stated.
Concept Introduction:
Fossil fuels like coal, petroleum and natural gases are accumulated in the earth over a very long time. They are present in limited quantity and once they get exhausted, they cannot be produced quickly in nature. So, Fossil fuels are known as the non-renewable source of energy. Petroleum is composed of the mixture of different hydrocarbons.
(b)
Interpretation:
Whether the octane rating of “straight-run” gasoline that is obtained by the fractional distillation of petroleum is greater than
Concept Introduction:
The measurement of the ability of gasoline to ignite properly inside an internal combustion engine is known as the octane number of gasoline. The efficient and smooth combustion corresponds to the large octane number.
(c)
Interpretation:
Whether the “straight-run” gasoline is used to fuel a car or not has to be predicted. The reason corresponding to the correct answer has to be stated.
Concept Introduction:
Power obtained from the utilization of chemical and physical resources, to do work is known as the energy. Gasoline is the source of chemical energy whereas hot gases are the source of heat energy. During the explosion of gasoline into hot gases, the chemical energy is converted into heat energy.
