This model is based on the kinetic theory and can be used to explore the relationship between pressure and volume of a gas at a constant temperature. In the model below, the inital conditions are set to a temperature of O°C (273 K), a volume of 22.4 dm3 and 1.0 mol of the gas argon, Ar.
To work with the model:
- choose new values of volume from the drop down menu
- press the update button to refresh the display
- press initialise to restore the starting value of volume = 22.4 dm3
- press clear to clear the display

The applet is based on the kinetic theory. Note that:
- the gas consists of particles (atoms or molecules) in continuous random motion
- the gas particles are point-like: they are infinitely small
- the gas particles move in a straight line unless they have a collision
- any attractive or repulsive forces between the particles are ignored unless the particles collide

These are the basic postulates of the kinetic theory.
