Factors Affecting Gas Pressure

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

  Move about in random directions
• What happens when gas particles hit the walls of a container?

  They rebound and change direction
• What do gas particles exert when they collide with container walls?

  A force that creates pressure
• How is pressure defined in terms of force and area?

  Pressure = force / area
• What two factors mainly determine total pressure in a gas?

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

  Pressure increases with temperature
• What happens to gas particles when heated?

  They gain kinetic energy and move faster
• What is the effect of increased concentration on gas pressure?

  Higher concentration leads to higher pressure
• What happens if the volume of a container is decreased while keeping the number of particles constant?

  Pressure increases due to more collisions
• How does volume relate to pressure in gases?

  As volume decreases, pressure increases
• What happens to pressure in flexible containers like balloons?

  Pressure changes with volume and temperature
• What occurs when the number of collisions increases in a gas?

  Pressure increases due to more force
• What is the relationship between collisions and pressure in a gas?

  More collisions result in higher pressure
• What happens to the pressure of a gas when its temperature is increased?

  Pressure increases due to faster particle movement
• What is the effect of a flexible container on gas pressure?

  It can expand or shrink with pressure changes
• What should you be aware of regarding expandable containers?

  They complicate the relationship between pressure and volume
• What factors affect gas pressure in a container?

  • Temperature: Higher temperature increases pressure
  • Concentration: More particles increase pressure
  • Volume: Smaller volume increases pressure
• How do temperature, concentration, and volume interrelate in gas pressure?

  • Temperature increases kinetic energy, leading to more collisions
  • Increased concentration means more particles collide with walls
  • Decreased volume results in more collisions per unit area
