Pressure (symbol: p) is the force per unit area acting on a surface in a direction perpendicular to that surface.
Pressure is transmitted to solid boundaries or across arbitrary sections of fluid normal to these boundaries or sections at every point.
It is a fundamental parameter in thermodynamics and it is conjugate to volume.
