particle motion in gas

• Temperature of a gas

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


  Particles have lower kinetic energy
• At low temperatures


  Fewer collisions per second and lower energy collisions
• At low temperatures


  Gas pressure is relatively low
• At high temperatures


  Particles have higher kinetic energy
• At high temperatures


  More collisions per second and higher energy collisions
• At high temperatures


  Gas pressure is relatively high
• You'll find plenty of questions on the pressure of gases in the revision workbook
