Describe the thermal effect of an explosion.

Explanation:
The thermal effect is the heat energy released by the explosion. When the explosive reaction happens, a huge amount of energy is liberated very quickly, and a portion of that energy appears as radiant heat that can burn exposed skin or ignite materials at a distance. A fireball or bright flash is a visible sign of this radiant energy, but the essential thermal impact is the heat that is generated and transferred. The other effects described—noise and vibration from blast waves, and structural collapse from overpressure—are mechanical effects, not thermal ones. So heat generation from the explosion is the best description of the thermal effect.
