Before Bell Rings Grab paper from side table Turn in P vs.T lab on front table Have your Boyle’s Law WS out for me to check

2. Plan for Today Entry Task Charles's Law – T and V relationship n vs V
Vacuum Chamber Demo
Work Time

3. Moles + Stoic Test
If you need to take/complete the test from last unit, come by this week during PH, before, or after school.

4. ETD 42
A ball at room temperature (25.0C) contains hydrogen gas at 10.0 atm. If the ball is carried outside to where the temperature is –20.0C, what will the new pressure be?
A 1.2 liter tank of oxygen gas is at a pressure of 30.0 atm. What volume of oxygen will be available if the oxygen is used at the normal atmospheric pressure of 1.0 atm?

5. ETD 42ANS
A ball at room temperature (25.0C) contains hydrogen gas at 10.0 atm. If the ball is carried outside to where the temperature is –20.0C, what will the new pressure be?

6. ETD 42ANS P1/T1=P2/T2 P1= 10.0 atm T1=25.0 C = 298.0 K P2= ? Atm
A ball at room temperature (25.0C) contains hydrogen gas at 10.0 atm. If the ball is carried outside to where the temperature is –20.0C, what will the new pressure be?
P1/T1=P2/T2
P1= 10.0 atm
T1=25.0 C = K
P2= ? Atm
T2= C = K
10.0atm/298.0 K= x atm/253.0 K =8.49atm

7. ETD 42ANS
A 1.2 liter tank of oxygen gas is at a pressure of 30.0 atm. What volume of oxygen will be available if the oxygen is used at the normal atmospheric pressure of 1.0 atm?

8. ETD 42ANS P1*V1 = P2*V2 P1= 30.0atm V1= 1.2 L P2=1.0atm V2=? L
A 1.2 liter tank of oxygen gas is at a pressure of 30.0 atm. What volume of oxygen will be available if the oxygen is used at the normal atmospheric pressure of 1.0 atm?
P1*V1 = P2*V2
P1= 30.0atm
V1= 1.2 L
P2=1.0atm
V2=? L
(30.0 atm)*(1.2 L)=(1.0 atm)(x L) =36 L

9. Learning Targets I can describe the relationship between T and V.
I can use Boyle’s, Gay Lussac’s, and Charles’ Laws to solve word problems.

10. Charles’ Law Describes the relationship between T and V
Pressure and amount of gas stay the same
What kind of relationship? Inverse or Direct

11. Charles’ Law
V1/T1=V2/T2
Temperature has to be in what units?

12. Charles’ Law Example
A sample of gas measures 1.50 liters at 0˚C. At what temperature will its volume become 4.50 liters, assuming pressure remains constant?

13. Charles’ Law Example
A sample of gas measures 1.50 liters at 0˚C. At what temperature will its volume become 4.50 liters, assuming pressure remains constant?

14. VERY IMPORTANT !!! Memorize these: Law name Equation Relationship
