Which amongst the following is not free state of carbon?

  1. Diamond

  2. Graphite

  3. Coke

  4. Petrol
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Diamond,graphite and coke exists in free state of carbon where as the petroleum is the mixture of hydrocarbons where carbon and hydrogen are present.So the substance which is not available in free state is petrol.
Hence option D is correct.

During fractional distillation, the crude petroleum is heated to a temperature of about:

  1. $600^{\circ} C$
  2. $400$ to $ 500^{\circ}C$
  3. $200^{\circ}C$
  4. $100^{\circ}C$

B Correct answer
Explanation

Fractional distillation of crude oil involves heating it to temperatures typically between 350 and 400 degrees Celsius to separate components based on boiling points. Option B is the closest standard range provided in educational materials.

B Correct answer
Explanation

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

B Correct answer
Explanation

 A. Carbonisation is applied to the pyrolysis of coal to produce coke.

 B. Cracking is the process whereby complex organic molecules such as kerosene or long chain hydrocarbon are broken down into simpler molecules such as light hydrocarbons by the breaking of carbon-carbon bonds in the precursors.
C. Refining is an industrial process plant where crude oil is processed and refined into more useful products such as petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene, and liquefied petroleum gas.
D. In the destructive distillation of powdered coal, heated coal turns to coke.

What is the source of sulphur dioxide emissions?

  1. Agricultural forms

  2. Petroleum refineries

  3. Hydroelectric power stations

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Sulphur dioxide emissions are given out by those industries which refine the sulphur containing products like petroleum refineries which employ catalytic processes to remove the sulphur from the petrol called as desulphurization which gives immense sulphur in the atmosphere as pollutant.

Producer gas is a mixture of:

  1. $CO\, and\, H _2$
  2. $CO\, and\, N _2$
  3. $SO _2\, and\, H _2$

  4. none of the above
Reveal answer Fill a bubble to check yourself
A,B Correct answer
Explanation
Producer gas is a mixture of flammable gases and non-flammable gases. Flammable gases are carbon monoxide and hydrogen. Non-flammable gases are mainly nitrogen and carbon dioxide.
Producer gas has lower heating value than the other gaseous fuels. It is used mainly as a fuel in large industrial furnace.
