What are fossil fuels?

• Synthetic materials created in laboratories
• Natural fuels formed from the remains of living organisms over millions of years.
• Minerals extracted from underground mines
• Renewable energy sources like solar and wind power

What are the different components we get during destructive distillation of coal?

• Coal gas, coal oil, coal residue

What is meant by destructive distillation?

• a material is heated to high temperatures in the absence of oxygen, causing it to break down into simpler substances

• a material is crushed into smaller particles, resulting in its transformation into new compounds

• a material is exposed to sunlight, leading to its decomposition into various elements

• a material is cooled to low temperatures in the presence of oxygen, causing it to break down into complex substances

What is the prosess of seperation of petroleum into different components?

• Chemical synthesis
• Biological extraction
• Fractional distillation
• Mechanical separation

What is coal made up of?

• Hydrocarbons

• Meteorite fragments
• Water

• Remains of animals

Which is a more cleaner fossil fuel

• Coal
• Diesel
• Kerosene
• Natural gas

What is the Indian association which monitors the level of fossil fuels?

• Petroleum Conservation Research Association (PCRA)
• Indian Fossil Fuel Monitoring Agency (IFFMA)
• National Association for Fossil Fuel Oversight (NAFFO)
• Fuel Conservation and Monitoring Authority of India (FCMAI)

Why do fossil fuels cause global warming?

• Fossil fuels emit oxygen into the atmosphere
• Fossil fuels absorb heat from the sun
• Fossil fuels cause global warming by releasing carbon dioxide and other greenhouse gases when burned.
• Fossil fuels reduce the Earth's temperature
