The correct answer to the question is:
A) Explosion
Explanation:
1. An explosion is a rapid expansion of gases resulting from a chemical action. This expansion creates a pressure wave that moves outward from the source of the explosion.
2. During an explosion, the sudden release of energy causes the gases involved to rapidly expand, generating a high-pressure wave that can cause damage to its surroundings.
3. Explosions can occur in various scenarios, such as chemical reactions, combustion processes, or even from the sudden release of compressed gases.
4. The pressure wave produced by an explosion can have destructive effects, making it important to handle explosive materials with care and follow safety precautions.
In summary, an explosion is the correct term for the rapid expansion of gases resulting from a chemical action that produces a pressure wave.
