Pressure and Volume - how to use the “PV=constant equation”

• What causes pressure in gases?

  Gas particles colliding with container walls
• How can we increase the pressure of a gas?

  By increasing temperature, number of particles, or decreasing volume
• What is the relationship between pressure and volume of a gas?

  Pressure and volume are inversely related
• If the volume of a gas increases, what happens to its pressure?

  The pressure decreases
• What is the pressure of a gas occupying 1.5 m³ at 100 Pa?

  150
• What units are used for the pressure in the gas cylinder example?

  Kilopascals
• What factors affect gas pressure in a container?

  • Temperature
  • Number of gas particles
  • Volume of the container
