In this activity, students investigate gaseous diffusion and effusion. After completing a laboratory experiment to gain a basic understanding of diffusion and effusion, students investigate carbon monoxide and hydrogen sulfide.

By the end of this activity, students should be able to:

  • understand the difference between diffusion and effusion
  • relate the diffusion of gases to the kinetic theory model for gases
  • link gaseous diffusion to the movement of toxic gases like carbon monoxide and hydrogen sulfide
  • provide a simple rap/poem/song to highlight the some of the dangers of poisonous gas diffusion.
