The effect of pressure and temperature on particles

The effect of pressure when a gas is heated

The pressure of a gas is due to the particles colliding with the walls of the container that the gas is held in

  • If gases are compressed into a smaller volume, there will be more particles hitting the container wall every second

  • The more frequent the collisions with the container wall the higher the pressure


  • Increasing the temperature makes particles move faster and increases the frequency of collisions with the container walls

  • Therefore, increasing the temperature increases the pressure if the volume stays constant
