Balloon in a bag - measuring pressure
#9
Our bag is not blown up and a very small increase of the air volume inside it ΔV (Δp/p)V = 0.03 V  does not increase the pressure inside (Δp=30hPa, p=1000Pa). Only a small peak when the bag adopts the new volume (its mass is not zero!) will appear. When I hit the bag with some air inside I observe a single sharp peak of about 1hPa (see the figure).

   

The origin of multiple peaks is still unclear.
