1. Before Bell Rings Grab two papers from side table 1 person from groups 1-7 log into a computer at your lab station Have your HW out for me to check

2. Plan for Today
Entry Task.
Boyle’s Law Lab.

3. ETD#39 A. Draw and explain what pressure is and measures?
B. The local atmospheric pressure is 692 mm Hg according to my barometer. What is the pressure in:
Atms
kPa
psi

4. ETD#39 ANS

Atms
kPa
psi

6. Learning Targets
I can describe the relationship between volume and pressure.

7. Notebook Check Checking entries 16-30 3 Points for each entry
1 for having the entry task number
1 for having the question written down
1 for having an answer written down
Self grade, putting your score out of 3 at the top of each entry
Also put the total out of 45 on the front page of your notebook.
Due class after next

8. Direct vs. Inverse Relationships
Relationships between two variables can be direct or inverse.
Direct relationship
One goes up, the other goes up
Represented by one variable divided by the other = constant (k)
Inverse Relationship
One goes up, the other goes down
Represented by the variables multiplied together = constant (k)

9. Boyle’s Law experiment with Syringes

10. Follow the Directions They are very clear
Pressure Sensor($70)
P sensor into CH1
ClickFileOpen
Chemistry with Vernier
 06 Boyle’s Law
Hand Draw Graphs
DON’T ADD .8 TO YOUR VOLUME
Start Syringe at mL then Connect
Creates a Closed System
Do Not Open the Syringe Between Trials

11. Boyle’s Law Syringe Lab
1. Determine the relationship between P and V
2. Get the following data.
2. Determine the mathematical relationship for P vs.V
