If coal has more energy per gram than nitroglycerin, why isn't its combustion considered an explosion?
A) Its lower explosion level (LEL) is too low for it to be considered a true explosion.
B) It requires too high an ignition temperature.
C) The rate is too slow.
D) The concentration is never high enough for an explosion.
Ignition Temperature
The minimum temperature required to cause a substance to ignite and continue burning independently without external heat sources.
Explosion Level
A term describing the concentration range of a substance in air within which the substance can explode.
- Understand the relationship between reaction conditions (temperature, concentration) and reaction speed.

Final Answer :
C
Explanation :
The rate at which coal combusts is significantly slower than that of nitroglycerin, which is why its combustion is not considered an explosion. Explosions require a rapid release of energy, and while coal may contain a high amount of energy per gram, it releases this energy slowly when it burns.
