Also, what is being decreased inside the syringe?
When the syringe plunger is pulled out, the volume of the chamber increases but the amount of gas remains constant because it is in a closed system. The pressure inside the syringe chamber decreases. The lower pressure on the marshmallow causes its vol- ume to increase according to Boyle's Law.
Beside above, what is an example of Boyle's Law in real life? Perhaps a more straightforward way is to say Boyle's law is the relationship between pressure and volume. An example of Boyle's law in action can be seen in a balloon. Air is blown into the balloon; the pressure of that air pushes on the rubber, making the balloon expand.
Also Know, what happened to the pressure and volume of air inside the syringe when the plunger was pushed in?
Because the air cannot escape from inside the syringe, when you then try to push in the plunger, the air inside the plunger is compressed into a smaller volume.
What happens to the gas pressure inside the syringe?
If you press on the plunger, you increase the pressure of the air and thus the air in the balloon contracts or decreases its volume. The opposite happens when you close the opening of the syringe and pull the plunger back. This time you decrease the pressure of the air inside the syringe—and its volume increases.
