Meaning
Gas pressure is the pressure on an object caused by a gas.
About Gas Pressure
- Pressure in gases is caused by particles colliding with the object or walls of the container.
- Each time a particle in the gas hits an object or the walls it provides a force.
- The more particles that hit the object or walls, the bigger the overall force it will experience.
- The faster the particles hit the object or walls, the bigger the force that each particle collides with.
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. |
