Question

The material A is a fossil fuel which is extracted from the earth. It is said to be formed from the buried, large land plants by a very slow process called carbonisation. When ‘A’ is heated in the absence of air in a process called ‘B’, it gives three products D, E and F. The product ‘D’ is used as a reducing agent in the extraction of metals, the product E is used as an industrial fuel whereas the product F has been traditionally used for metalling the roads. (a) What could be the material ‘A’? (b) What is the (i) physical state and (ii) colour of ‘A’? (c) Name the process ‘B’. (d) What are D, E and F?​

Answer 1

Answer:

Coal is a fossil fuel. It was formed by the process of carbonisation. Carbonisation is the process by which plant material or vegetation buried deep under the earth was slowly converted into coal. This is a very slow process and usually takes millions of years.
