Answer to Question #25952 in Molecular Physics | Thermodynamics for Mustarin Tamanna

Question

pressure is a kind of force ,so why it is called pressure

Answer 1

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.
