Dear all,

 

Why is pressure defined as an intensive property?

 

Pressure is defined as the sum of the forces(perpendicular to the area under consideration) exerted by molecules of the fluid per unit area.

 

Say,there is a vessel containing gas exerting a pressure of X bar.When a significant amount of gas is removed,pressure exerted by the gas decreases.This is understandable since force is function of mass.

Therefore,pressure exerted by a mass of fluid depends of depends on the amount of molecules contained in the mass.This is contradictory to temperature - an intensive property ,whose value remains unchanged irrespective of the amount of fluid present in the vessel.

 

I'm not able to wrap my head around the idea that pressure is an intensive property.Kindly help
