Carbon and Fossil Fuels Questions
-
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.
-
Tough,black and porous
-
Black, thick liqid and unplesant smell
-
Black , and soft
-
None
B
Correct answer
Explanation
Coal tar is a black, thick liquid with an unpleasant smell, which is a byproduct of the destructive distillation of coal.
-
Paraffin wax
-
Coal tar
-
Bitumen
-
None of these
C
Correct answer
Explanation
Bitumen is a petroleum product that is sticky, black, and highly viscous, making it ideal for road surfacing and waterproofing.
-
Nitrogen gas
-
Carbon dioxide gas
-
Hydrogen gas
-
Oxygen gas
B
Correct answer
Explanation
Coal is primarily carbon; when it burns in the presence of oxygen, it reacts to form carbon dioxide gas.
-
Cellulosic Manufactured Fibers
-
Synthetic Fibers
-
Protien Fibers
-
Manufactured Fibers
B
Correct answer
Explanation
Synthetic fibers are chemically manufactured from petrochemical sources like crude oil and natural gas. Manufactured fibers is a broader category that includes both synthetic and cellulosic types.
-
Gum
-
Amber
-
Both Gum and Amber
-
None of these
B
Correct answer
Explanation
The word electricity is derived from the Greek word for amber, 'elektron'. Thales of Miletus observed that rubbing amber with fur produced static electricity, which can create small sparks.
-
Fossil Fuels
-
Solar Fuel
-
Geothermal
-
Hydrothermal
A
Correct answer
Explanation
Fossil fuels, such as coal, oil, and natural gas, are energy sources formed from the remains of ancient plants and animals buried over millions of years.
-
Flammable
-
Corrosive
-
Toxic
-
Caution
A
Correct answer
Explanation
Flammable materials are substances that can easily ignite and burn when exposed to a flame or spark.
-
Explosive
-
Caution
-
Toxic
-
Implosive
A
Correct answer
Explanation
Explosive materials are defined by their capacity to release energy rapidly and violently. Implosive is the opposite, involving a collapse inward.
-
Combustion
-
Decomposition
-
Synthesis
-
Oxidation
A
Correct answer
Explanation
Combustion is a high-temperature exothermic chemical reaction between a fuel and an oxidant (usually oxygen) that produces heat and light.
-
Gum
-
spices
-
fodder
-
kerosene
D
Correct answer
Explanation
Gum, spices, and fodder are biological products derived from forest plants. Kerosene is a fossil fuel product derived from petroleum.
-
Internal combustion engine
-
Electricity
-
Motorcycles
-
Natural gas
A
Correct answer
Explanation
The development of the internal combustion engine allowed for the use of liquid fuels like gasoline (derived from oil), which eventually replaced coal as the primary power source for transportation.
-
petroleum
-
coal
-
natural gas
-
diamonds
A
Correct answer
Explanation
Petroleum is a fossil fuel extracted from the Earth and refined into products like gasoline. Coal and natural gas are also fossil fuels, but petroleum is the primary source for gasoline.
-
coal
-
water
-
oil
-
natural gas
B
Correct answer
Explanation
Fossil fuels are hydrocarbons formed from ancient organic matter. Water is a renewable resource and not a fuel source formed from fossils.
