What happens when an inflated air balloon is pricked with a pin? Name the property of thegaseous state exhibited by this observation.

When an inflated air balloon is pricked with a pin, the following happens:

1. The pin punctures the balloon's surface, creating a hole.
2. The air inside the balloon is under pressure, so when the balloon is punctured, the air rushes out quickly.
3. This rapid escape of air causes the balloon to burst or deflate quickly.

The property of the gaseous state exhibited by this observation is called "compressibility". Gases are compressible, which means they can be easily squeezed or compacted. In the case of the balloon, the air inside is compressed. When the balloon is punctured, the compressed air expands rapidly, causing the balloon to burst.
