Carbon and Fossil Fuels Questions
-
mercury
-
liquid diamond
-
liquid gold
C
Correct answer
Explanation
Petroleum is frequently referred to as liquid gold due to its immense economic value and importance in the global economy.
A
Correct answer
Explanation
Petrol (gasoline) is a refined product of petroleum and is widely used as a fuel for internal combustion engines in motor vehicles.
D
Correct answer
Explanation
CNG (Compressed Natural Gas) is considered a cleaner fuel compared to petrol, diesel, or coal because it produces fewer harmful emissions, such as carbon monoxide and particulate matter.
C
Correct answer
Explanation
Fossil fuels are generally categorized into three main types: coal, petroleum (oil), and natural gas.
-
Petrolium conservation
-
Petrolium coal reservation Association
-
Petrolium conservation Reservation linstitute
-
Petrolium conservation Research Association
D
Correct answer
Explanation
PCRA is the Petroleum Conservation Research Association, an Indian government organization established in 1978 to promote energy efficiency and conservation in the petroleum sector. Note: correct spelling is 'Petroleum' not 'Petrolium'.
B
Correct answer
Explanation
Petrol and diesel are both refined products obtained from crude oil, which is petroleum. Therefore, the statement that they are not obtained from petroleum is false.
-
Refining
-
Degradation
-
Carbonisation
-
None of these
C
Correct answer
Explanation
Carbonisation is the slow process by which vegetation (like wood) is converted into coal under high pressure and temperature over millions of years.
B
Correct answer
Explanation
Diesel is a fuel derived from petroleum, which is a fossil fuel. Therefore, the statement that diesel is not a fossil fuel is false.
A
Correct answer
Explanation
Natural gas, coal, and petroleum are all fossil fuels. They are formed over millions of years and exist in limited quantities, making them exhaustible.
-
Liquid petrolium gas
-
Liquified petrolium gas
-
Compressed natural gas
-
None
B
Correct answer
Explanation
LPG stands for Liquified Petroleum Gas, not Liquid Petroleum Gas. The term 'Liquified' is more accurate because the gas is compressed and cooled to convert it into liquid form for storage and transportation.
-
Coal tar
-
Coke
-
Coal gas
-
None
B
Correct answer
Explanation
Coke is a tough, porous, and black substance that is an almost pure form of carbon. It is obtained by processing coal in the absence of air.
A
Correct answer
Explanation
Coal tar is a complex mixture of substances used as a starting material for manufacturing various products, including synthetic dyes, drugs, explosives, perfumes, and plastics.
-
For making candles ointments and Vaseline.
-
For making paints
-
For lubrication
-
None
A
Correct answer
Explanation
Paraffin wax is a white, solid substance obtained from petroleum refining, commonly used in products like candles, ointments, and Vaseline due to its waxy properties.
-
Coal
-
Coke
-
Petroleium
-
Natural gas
C
Correct answer
Explanation
Petroleum is often referred to as black gold because of its immense commercial value and dark, viscous appearance when extracted from the ground.
