Why does an inflated paper bag burst loudly when hit with a strong hand?

When an inflated paper bag is hit with a strong hand, it bursts loudly due to a combination of factors. Let's explore these factors in more detail:

1. Air Pressure: When a paper bag is inflated with air, the air inside creates pressure against the walls of the bag. The pressure inside the bag is higher than the atmospheric pressure outside. This pressure difference keeps the bag inflated.

2. Structural Integrity: The structural integrity of the paper bag plays a crucial role in determining its ability to withstand external forces. Paper bags are typically made of thin, lightweight materials that are not very strong. The bag's ability to withstand pressure depends on the strength of the paper and the quality of its construction.

3. Force of Impact: When a strong hand strikes the inflated paper bag, it applies a significant force to the bag's surface. This force compresses the air inside the bag, increasing the pressure even further.

4. Weakest Point: The force of the impact is concentrated on a specific area of the bag's surface. This area becomes the weakest point of the bag, where the pressure is highest. The weakest point is usually where the bag is most likely to burst.

5. Failure of the Bag: When the force of the impact exceeds the bag's ability to withstand the pressure, the weakest point of the bag gives way, causing the bag to burst. The sudden release of the pressurized air creates a loud noise, similar to a small explosion.

In summary, an inflated paper bag bursts loudly when hit with a strong hand because the force of the impact exceeds the bag's ability to withstand the pressure, causing the weakest point of the bag to give way and release the pressurized air.
