Correct answer: D. Ignition temperature
- A. Smoking tendency on burning
- B. Coke oven gas yield on carbonisation
- C. Chance of catching fire during storage in open space
- D. Ignition temperature
Explanation
Volatile matter escapes readily on heating, so coal with more volatile matter ignites at a lower temperature. It generally burns with more flame and smoke, rather than having a reduced smoking tendency.
