Gas pressure is the pressure on an object caused by a gas.

Pressure in gases is caused by particles colliding with the object or walls of the container.


The particle model of a gas showing the particles as red balls and their speed and direction shown by the arrows. The longer the arrows the faster they are moving.

The gas pressure can be increased in two ways.


Increasing the temperature of the gas which makes the particles move faster. This causes the particles to hit the walls of the container more often and with a greater force.	Increasing the number of particles in the container.
