Question

What happens if there is higher carbon content in the coal?

  1. More pollution
  2. More clean air
  3. More efficiency of coal
  4. More time need for burning of coal

hintHint:

More efficiency of coal

The correct answer is: More efficiency of coal


    The typical carbon content for coal (dry basis) ranges from more than 60 percent for lignite to more than 80 percent for anthracite. Anthracite is the grade of coal that has the highest percentage of carbon followed by bituminous coal, lignite and peat. Higher the grade of a coal, lower is its ash content and thus greater combustibility.

    _________is not a fossil fuel.

    The correct option is c)Thorium.
    Fossil fuels are made by decomposing plants and animals. These fuels are found in the Earth's crust and contain carbon and hydrogen that can be burned to produce energy. Coal, oil and natural gas are examples of fossil fuels. Fossil fuels are non-renewable resources and waiting millions of years for new deposits of coal, oil and natural gas to form is not a viable solution.
