Low temperature carbonisation of coal takes place at ______________ °C?
Correct answer: C. 700
- A. 300
- B. 1100
- C. 700
- D. 150
Explanation
Low-temperature carbonisation is commonly carried out around 500 to 700°C, whereas high-temperature carbonisation is usually near 900 to 1100°C. Thus, 700°C is the suitable listed value.
