Particle Motion in Gases

• How does changing the temperature of a gas affect its pressure?

  It changes the number and energy of collisions
• What is the state of particles in a gas?

  Constant random motion
• What causes the pressure of a gas?

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

  Increase collisions per second or energy
• What happens to gas particles at low temperatures?

  They have lower kinetic energy and fewer collisions
• What is the relationship between temperature and kinetic energy of gas particles?

  Higher temperature means higher average kinetic energy
• How does gas pressure change with temperature?

  Pressure increases with higher temperatures
• What is the effect of high temperatures on gas particles?

  They have higher kinetic energy and more collisions
• What are the key concepts related to gas temperature and pressure?

  • Temperature relates to average kinetic energy
  • Low temperature = lower pressure
  • High temperature = higher pressure
  • Pressure is due to particle collisions
