Particle motion of gas

• What is the pressure of gas due to?

  The particles colliding with the walls of the container the gas is held in
• How can we increase the pressure of a gas?

  Increasing the number of collisions per second / the energy of each collision
• How can you increase the collisions in a gas?

  Increase the temperature of the gas

  this will increase the kinetic energy of particles

  so more frequent collisions with greater forces being exerted in collisions

  on the same area
• What is the pressure of gas at low temperatures and high temperatures?


  low temperatures - low pressure high temperatures - high pressure
