A coal having higher volatile matter content will necessarily have lower____________________?
Correct answer: C. Ignition temperature
- A. Ash fusion temperature
- B. Calorific value
- C. Ignition temperature
- D. Caking index
Explanation
A higher volatile-matter content generally makes coal ignite more readily, so its ignition temperature is lower. Volatile matter alone does not necessarily determine ash fusion temperature, calorific value, or caking index.
