About Gas Pressure
- 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.
