10. Charles Law Notes

11. What does temperature measure?
The average kinetic energy of the molecules
If temperature is increased what happens to the speed of the molecules?
Increases
If temperature is decreased, what happens to the speed of the molecules?
Decreases

12. Charles Law Analyzes the relationship of volume and temperature
Pressure is held constant

13. Charles’s Law
If the temperature of a gas increases, the volume of a gas increases
This shows a direct relationship between V and T
Temperature must be in Kelvin (Celsius + 273)
V1 = V2
T1 T2

14. Charles’s Law

15. Charles’s Law _16.0_ _V2_ 273 = 308 V2 = 18.1 L
Example: L of oxygen gas occupies a gas cylinder at 0.00ºC. What will be the volume of the gas if the temperature is increased to 35.0ºC? (Hint: Celsius  Kelvin)
_16.0_
273
_V2_
308 =
V2 = 18.1 L
