particle motion in gases

• How is the temperature of a gas related to the energy of its particles?

  Temperature relates to average kinetic energy
• What happens to gas pressure when the temperature changes?

  Changing temperature alters gas pressure
• What is the state of particles in a gas?

  Particles are far apart and in motion
• What causes the pressure of a gas?

  Particles colliding with container walls
• How can you increase the pressure of a gas?

  Increase collisions or collision energy
• What effect does increasing the temperature of a gas have on particle collisions?

  It increases the number and energy of collisions
• What happens to gas pressure at low temperatures?

  Gas pressure is relatively low
• What happens to gas pressure at high temperatures?

  Gas pressure is relatively high
• How does the kinetic energy of particles change with temperature?

  Higher temperature means higher kinetic energy
• What are the key ideas about gas pressure and temperature?

  • Temperature relates to average kinetic energy
  • Low temperatures lead to fewer, lower energy collisions
  • High temperatures lead to more, higher energy collisions
  • Pressure increases with temperature due to more collisions
