Syringe inside a Vacuum Chamber
Up until now, we’ve been changing the air particle density inside of a syringe by pushing down or pulling up on its plunger when its blue cap is on. But that’s not the only way we can change the air particle density of a closed system. This time, we will change the air particle density around a syringe by placing it inside a sealed vacuum chamber and then seeing what happens as we suck out half the air.
By now, you should have been able to predict that the plunger in the syringe would move up. In fact, knowing that we are sucking out exactly half the air from the box, you should have been able to predict that the plunger would move from 15 up to 30. However, if you still need help visualizing the air particles in the syringe and in the box so that you can predict what will happen, you can always check out this explanation.
