## What is pressure determined by?

### • Air density and thickness of atmosphere• P=pgh

Pressure is determined by the force acting on a unit area of a surface. It is defined as the ratio of force to the surface area over which the force is applied. Mathematically, pressure = force/area or P = F/A, where P is pressure measured in pascals (Pa), F is the force applied in newtons (N), and A is the area of the surface in square meters (m²). Thus, the greater the force applied over a smaller area, the greater the pressure, and vice versa.
