1. Chapter 3 - Review
Bellwork – Predict what will happen & What gas law is depicted by the following demonstration?

2. TN State Standards
CLE – Investigate chemical and physical changes
CLE – Investigate relationships among the pressure, temperature, and volume of gases and liquids

3. Gas Laws What are they by name?
Two conditions vary while the third is held constant – what are these three CONDITIONS?

4. Pascal / Bernoulli
Which one relates to static fluids and which one relates to moving fluids?

5. Pascal / Bernoulli
A change in pressure at any point in an enclosed fluid will be transmitted equally to all parts of the fluid ( which one is this ? )
As the speed of a moving fluid increases, the pressure of the moving fluid decreases
( which one is this ? )

6. Buoyancy - Archimedes
What is buoyancy?
What is Archimedes’ Principle?

7. State Changes of Matter
What is always conserved even through a state change?
Is energy absorbed or released by the substance undergoing the state change?
What are the state changes?

8. What is Happening? Evaporation
Your body heat gets transferred to the rubbing alcohol and it evaporates
This gives that part of your skin a “cooling” sensation

9. Challenge – In Your Notes
Fog: which of the 5 state-changes does fog represent?
When/Where does fog form
Is energy absorbed or released when fog forms?
Is energy and mass conserved when fog forms?

10. Exit Pass On a Whiteboard, make a table with 3 columns and 4 rows
list four ( 4 ) common, everyday examples of state-changes in first column
Put which of the 5 state changes they are in middle
List whether energy is released or absorbed on right

11. Exit Pass
Draw a picture that indicates a state-change ( you choose !! ) then label which of the 5 state-changes it is and whether energy is added or removed [from the substance changing].
