Understand that by using a syringe is the good
example of showing the air pressure movement. As you pull the syringe plunger
out, there is an increase of fluid, and if you push it in, the chance of
decreasing the fluid will happen. In this case, you will find the state of mass
and volume. By comprehending the air pressure, firstly take a note to
understand the properties of air. The force of air pressure in a syringe causes
the reduce of weight when we try to raise the density of the air in a
compressed manner.
