Question

What is pressure. how does it change with area

Answer 1

pressure is the force over per unit area. it changes as lesser the area larger will be the pressure. Mark brainliest if you like

Answer 2

It is the ratio of the force applied to the surface area over which the force is applied. Since the pressure is dependent on the area over which the force is acting, the pressure can be increased and decreased without any change in the force.For example a brick sitting on a surface exerts a force equal to its weight on the object it is resting on. Now we know that a rectangular brick has a wide surface and a thin surfaces on the sides. By changing the orientation of the brick resting on a surface, we are effectively changing the pressure acting on the surface by the same brick. See the image below for more information.
