When the plunger is pulled, the volume inside increases. This reduces the pressure inside, and the air pressure outside forces liquid in, in an effort to make the pressure inside and outside the syringe equal again.

you can soak it in a high concentration of salt water which causes it to lose its turgor pressure ,therefore it shrinks in size by diffusional water from inside the potato moves to the salt solution)
The air pressure is the same, inside or outside the paper bag.
The pressure in a container is due to the particles of the gas hitting the inside walls of the container.

A piston is a plunger, or a plug that moves inside a cube, a cylinder. The piston diameter is the diameter of this plunger/plug. It's a tiny bit smaller than the diameter of the cylinder the piston moves in.
The difference between a piston and a plunger may be understood if you observe what forms the seal that precludes the fluid from passing either the Plunger or Piston. The 'piston' is a steel block equipped with elastomers that makes wall contact with the cylinder wall. As it moves inside the cylinder it wipes the wall and displaces the entire content of the cylinder. In this case the seals form part of the piston. The 'plunger' is a steel block that moves through a hole that is equipped with elastomer seals. The plunger displaces a portion of the cylinder contents, i.e., the volume of the plunger that enters the cylinder. The plunger does not wipe the walls of the cylinder. The seals, in case, are a part of the cylinder block. Umair Aslam Mechanical Engineer PARCO, Pakistan
Measure to the edge of the plunger (or piston) where it touches the inside of the syringe cylinder. http://www.northcumbriahealth.nhs.uk/palliativecare/clinical/syringe/05.php
if the cylinder is on the inside, it would not affect the surface area. otherwise, subtract the part of the inside cylinder that touches the outside from the cylinder
The standard CBR600F (ie 1987-1989 models) cam chain is tensioned by a plunger inside a housing bolted to the centre rear of the cylinder block. This plunger pushes on the cam chain rear guide. There is no external or manual adjustment, instead, the plunger is under spring pressure and engine oil pressure. Some people consider that the original tensioners are unreliable, and aftermarket manual tensioners are available. APE makes one, and their website shows how to adjust it.
they bounce and hit each other inside the cylinder and cause the pressure.
The pressure from the air inside of it
Gas expands when heated and shrinks when cooled. If the gas inside a closed cylinder is cooled, it will shrink, so it will push against the walls less. Therefore, less pressure.
