Compression and Expansion of air

Along with the sixth graders in Udavi we did an experiment that indicated on how air behaves in various pressures. All we needed was a syringe, and a balloon. and we got started. The children took the balloon and kept it inside the syringe and gave pressure. They noticed that the balloon shrunk in size.

This they concluded was because of the intense pressure it created to the captured air.



Then they expanded the air and saw that the balloon drastically increased in size, and this was due to expansion of air and created low pressure.
