Question

an explosion is an example of ____.
○ fusion
○ combustion
○ instant oxidation
○ detonation

Explanation:

To solve this, we analyze each option:

• Fusion: Combining light nuclei (e.g., in stars), not explosions.
• Combustion: Rapid burning (e.g., fire), slower than explosion.
• Instant oxidation: Oxidation (like rusting) is slow, not explosive.
• Detonation: A rapid, violent explosion with shock waves, matching an explosion's nature.

Answer:

D. detonation
