The force of all gas particle/wall collisions divided by the surface area of the wall is the definition of pressure (P): One of the fundamental quantifiable variables of this phase of matter, pressure, is a property shared by all gases.
The physical amount of force applied to a certain region is known as pressure. Pressure is defined as force per unit of area. The pressure being applied to a body can be calculated by taking the amount of force being applied and dividing it by the area of contact.
