With reference to fossil fuels, consider the following statements :
- 1Coal is the most abundant fossil fuel and has high specific energy and energy density.
- 2The action of heat and pressure changes plant matter in stages from anthracite to bituminous to lignite coal.
Which of the statements given above is/are correct?
general-sciencechemistry
- A2 only
- B1 only
- CBoth 1 and 2
- DNeither 1 nor 2
Explanation
Coal is the most abundant fossil fuel by reserves and a high-energy-density fuel — statement 1 is correct as framed. But the coalification sequence runs from peat to lignite to bituminous to anthracite with increasing heat and pressure (carbon content rising); statement 2 reverses it to anthracite-to-lignite, which is wrong. Hence only statement 1 is correct.
