C Correct answer
Explanation

Glycol added to petrol acts as anti -icing agent

Anti -icing is a application of chemicals that not only de-ice, but also remain on a surface and continue to delay the reformation of ice for a certain period of time, or prevent adhesion of ice to make mechanical removal easier.

Which of the following is desirable in diesel and kerosene but is undesirable in gasoline?

  1. Paraffins

  2. Mercaptans

  3. Aromatics

  4. Naphthenic acid
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Aromatics are desirable in diesel and kerosene but is undesirable in gasoline. It is a mixture of paraffin (alkanes), cycloalkanes (naphthenes), and olefins (alkenes). Aromatics are a base component of gasoline derived from crude oil. Refiners manipulate these substances – mainly mixtures of chemicals like benzene, toluene, and xylene – to increase the octane rating, a measure of how well the fuel actually works.

The layer containing petroleum oil and gas is:

  1. below water

  2. between water and sand

  3. below sand

  4. above the water
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The density of gasoline ranges from 0.71–0.77 kg/L, where as that of water is 1kg/L, oil is less dense than water so it will "float" on water. Gas is less dense than both and will float to the top. higher densities having a greater volume of aromatics. Since gasoline floats on water, water cannot generally be used to extinguish a gasoline fire unless used in a fine mist. The petroleum products will separate by density.
