Music: Kevin MacLeod A partially filled balloon is placed into a vacuum chamber. Whe the vacuum is turned on the pressure exerted on the balloon decreases and the balloon can expand until the bell jar is completely filled. When the air is allowed back in the jar, the pressure is reestablished and the balloon returns to its original volume. This is a great example of Boyle's Law which shows an indirect relationship between pressure and volume.

Thank you

K then
The vacuum just takes the air away from outside the balloon, so the air inside the balloon more room to expand with less resistance?
