Gases and Particle Models

Learners use the kinetic-molecular model to explain gas pressure and temperature, then derive and apply the gas laws: Boyle's, Charles's, Gay-Lussac's, the combined law and the ideal gas law. They link gas volumes to stoichiometry and finish by asking when the ideal model breaks down for real gases.

  • 4 lessons
  • About 110 minutes
  • Gases check: 10 questions
  • Ways to answer: choose an answer, draw a graph, type a number, place on a number line, put in order and sort into groups

What learners will discover

  • Explain pressure and temperature with the kinetic-molecular model and convert between degrees Celsius and kelvin.
  • Apply Boyle's law to pressure–volume changes and explain the inverse relationship with particle collisions.
  • Apply Charles's law, Gay-Lussac's law and the combined gas law using absolute temperature, and interpret their graphs.
  • Use the ideal gas law and molar volume, including in stoichiometry, and identify conditions where real gases deviate from the ideal model.
