Particle motion in gases

• Temperature of a gas

  Related to the average kinetic energy of the particles
• At low temperatures


  Particles have lower kinetic energy, fewer collisions per second, lower energy collisions, lower gas pressure
• At high temperatures


  Particles have higher kinetic energy, more collisions per second, higher energy collisions, higher gas pressure
• You'll find plenty of questions on the pressure of gases in the revision workbook
