A coal having high volatile matter content will ________________?
Correct answer: D. None of these
- A. Give less yield of tar and gas on carbonisation
- B. Burn with a small non-smoky flame
- C. Have a very high calorific value
- D. None of these
Explanation
High-volatile coal produces greater quantities of tar and gas during carbonisation and generally burns with a long, smoky flame. Therefore all three stated descriptions are false, making none of these the appropriate choice.
