factors affecting gas

• What are gas particles free to do in a container?

  Move about in random directions
• How do gas particles create pressure in a container?

  By colliding with the walls and exerting force
• What is pressure defined as?

  Force exerted per unit area
• What two factors mainly determine total pressure in a gas?

  Number of collisions and energy of collisions
• How does temperature affect gas pressure?

  Higher temperature increases particle speed and collisions
• What happens to gas particles when heated?

  They gain kinetic energy and move faster
• If the concentration of gas particles increases, what happens to pressure?

  Pressure increases due to more collisions
• How does volume affect gas pressure?

  Decreasing volume increases pressure with constant particles
• What is the relationship between particle concentration and pressure?

  Higher concentration leads to more collisions and higher pressure
• What happens to pressure when the volume of a container decreases?

  Pressure increases as particles collide more frequently
• How do flexible containers like balloons behave with changes in temperature and concentration?

  They expand or shrink instead of increasing pressure
• What happens to a balloon when the number or force of collisions increases?

  The balloon expands rather than increasing pressure
• What should students be aware of regarding expandable containers?

  They complicate the relationship between pressure and volume
• What are the main factors affecting gas pressure?

  • Temperature: Higher temperature increases pressure
  • Concentration: More particles lead to higher pressure
  • Volume: Smaller volume increases pressure
• How do gas particles behave in a container?

  • Move randomly in all directions
  • Collide with walls, exerting force
  • Create pressure through collisions
