Particle Motion in Gases

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

  It changes the pressure of the gas
• What is the state of particles in a gas?

  They are very far apart and in constant motion
• What causes the pressure of a gas?

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

  Increase collisions per second or energy
• 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
• What is the relationship between temperature and average kinetic energy of gas particles?

  Temperature is related to average kinetic energy
• What occurs to particle collisions at high temperatures?

  There are more collisions per second
• What type of collisions occur at low temperatures?

  Fewer and lower energy collisions
• Where can you find more questions on the pressure of gases?

  In the vision workbook
• What is the main focus of this video?

  Pressure of gases and temperature relation
• How does the average kinetic energy of particles change with temperature?

  It increases with higher temperatures
• If the temperature of a gas is increased, what happens to the energy of the particles?

  The energy of the particles increases
• Why do gas particles exert pressure on the container walls?

  Due to collisions with the walls
• What is the effect of low temperatures on gas collisions?

  Fewer collisions occur
• What is the relationship between kinetic energy and temperature in gases?

  Higher temperature means higher kinetic energy
• How does the pressure of a gas change with temperature?

  Pressure increases with temperature
• If you want to increase the pressure of a gas, what should you do to its temperature?

  Increase the temperature of the gas
