Answer to Question #25952 in Molecular Physics | Thermodynamics for Mustarin Tamanna
pressure is a kind of force ,so why it is called pressure
When a force is applied on a surface in a directionperpendicular to the surface, the force is called thrust. Pressure on a solid surface is the thrust per unit areaof the surface. Pressure = Thrust / area Pressure is a scalar quantity. The SI unit of Pressure isN m - 2 or Pascal (Pa) Pressure varies according to the area over which the force is exerted.
