Pressure:
It is define as the physical force acting on an object.
It is expressed as force per unit area, and can be calculated by using following formula.
P =F/A
p = pressure
F = force
A = area
This force is perpendicular to the surface of object.
Units:
Its system international unit is pascal (Pa) and one pascal is equal to the N/m².
The atm is also used to express the pressure. It is stand for atmosphere and one atm is equal to the 101325 Pa.
