Pressure is defined as the amount of force acting on a given area. Thus, the mathematical equation of pressure is force divided by area. This equation can be rearranged to solve for force. When done so, force equals pressure times area.

Pressure is caused by the collision of particles with a surface. Although they cannot be seen with the unaided eye, there are gas particles surrounding us. These particles are in constant motion. The particles collide with one another and other surfaces. The more that a surface is bombarded by particles, the greater the pressure.

Pressure often increases as temperature increases. Temperature is a measurement of the average kinetic energy obtained by the particles that make up a substance. Kinetic energy is the energy of motion. Thus, an increase in the temperature of a substance implies that the average kinetic energy of the particles of the substance has increased. As the kinetic energy of the particles increases, the particles begin to move faster and more often. Thus, as temperature increases, the particle bombard surfaces more often and pressure increases also.
