What is pressure and what causes it?

Bumping particles. The particles in a gas move quickly in all directions, but they don't get far before they bump into each other or the walls of their container. When gas particles hit the walls of their container they cause pressure.

People also ask, what is the formula used to calculate pressure?

Pressure is defined as force per unit area. It is usually more convenient to use pressure rather than force to describe the influences upon fluid behavior. The standard unit for pressure is the Pascal, which is a Newton per square meter.

What can pressure be used for?

pressure (symbol Pa) In physics, the force on an object's surface divided by the area of the surface. The SI unit is the pascal; 1 pascal is equal to the pressure exerted by a force of 1 newton on an area of 1m 2. In meteorology, the millibar (symbol mb), which equals 100 pascals, is commonly used.
