Q & A: Syringe Physics | Department of Physics ...

Oct 22, 2007 · Alex- thanks for the tip. I see only one correction that's really needed. When you pull back on a syringe you increase the volume V that the air is distributed in. That causes (approximately) the pressure to go down as 1/V. Of course this pressure isn't zero, but it is less than atmospheric pressure.

How to Prevent Air Bubbles from Causing Piston Bounce
