What happens if you put balloons in a vacuum chamber?
Why do the balloons expand inside the vacuum chamber?
This happens because of Boyle's law which includes pressure,temperature, and volume.
In a vacuum chamber gases get taken
out. When the air gets taken out the pressure decreases. This can be explained with Boyle's Law. Boyle's Law states that when pressure decreases volume increases and vice versa.
Now what does this have to do with a balloon you ask? Well if we put a balloon in a vacuum chamber the only gases trapped inside are the gases in the balloon and in the chamber. When turning on the vacuum all the air will get taken out thus decreasing the pressure and increasing the volume. When the gases inside a balloon gets taken out the balloon will expand because there is a lot less pressure.
