Catalyst• In your journal, respond to the following

question:Would it be a good idea to inflate my road bike

tires to high pressures in Los Angeles during the summer? Why or why not? Think CHEMISTRY!

Pressure Stations!

• Groups of 4 (we will number off)• Each station has an activity and 2-3 journal

questions that you are responsible for.• Your exit ticket today is your individual

journal responses. I will be checking these before you leave today.

Lecture 6.2 – Pressure Effects

Learning Target (Review)• LT 6.1 – I can explain how pressure is created

through the collisions of molecules with a surface.

I. Pressure vs. Temperature• Thermal energy – energy that is related to

temperature.• Pressure increases with increasing thermal

energy.

II. Pressure vs. # of Molecules

• Pressure increases with the # of gas molecules…why?– More molecules = more

collisions

III. Pressure vs. Altitude• Pressure decreases with altitude (as we go

higher up in the atmosphere)…why???– Gravity– Temperature decreases

IV. Pressure vs. Depth

• Pressure increases with depth (below the surface of the ocean)…why?– Weight of water

creates pressure

Label It!

• In your journal, please label your station activities as either: pressure vs. temperature, pressure vs. # of molecules, pressure vs. altitude, or pressure vs. depth.

• This is your exit ticket for today and your journal will be graded!

Closing TimeClosing Time• Homework: HW6.1 set due Thursday/Friday.

This will be graded!• Binder tabs, binder, and notebook are

required.
