  1. What happens when 1 million bouncy balls are let loose? San Francisco Ballapalooza

  2. Justify – TPS How can the bouncy balls act as an analogy for molecules being released? Why didn’t they bouncy balls stay in the same place? What made them move? EVERYONE MUST WRITE SOMETHING!

  3. Objectives • SWBAT discuss how the pressure on a surface is created. • SWBAT draw how diffusion of gases occurs Put it in your learning logs!

  4. Gases • Gases are one of three states of matter. • They move in constant random motion. • They fill an entire container and are spread very far apart from one another.

  5. What Gases Look Like at Atomic Level

  6. Pressure • The collisions of gas molecules with a surface are what creates pressure. • Pressure the amount of force that is exerted per unit area of surface. • Student-Wall Demonstration

  7. Pressure Has Many Units • Pressure is measured with a barometer and it is measured in many different types of units. • The units of pressure are atm, bar, mm Hg, Pa, and torr.

  8. The Sad Story of My First Love

  9. Justify – TPS • Why did the people closer to the air canister smell it sooner then the people further away from it?

  10. Diffusion • Diffusion is the movement of particles from regions of higher density to regions of lower density. • Because gases are constantly moving in random motion, they spread out from one another very quickly. • The random motion of gases is what explainsthe process of diffusion and the rate at which gases diffuse. • Gases move very fast. Therefore, gases diffuse through a room at a relatively fast rate.

  11. You’ve Seen Diffusion Before!

  12. Summarize

  13. Exit Tweet • In 140 characters or less, summarize how pressure is created and why the motion of gases explains diffusion.

  14. Closing Time • No Homework tonight • If you are still confused on stoich., you should come in for tutoring today or Thursday after school to get help. • Stoichiometry will keep coming up for the rest of the year so you need to master things you do not understand!
