1. Gay-Lussac’s Law -Assumes constant concentration of gas and volume
-Temperature MUST be in Kelvin
-pressure and temperature increase together directly proportionally
ex. if pressure doubles, temperature doubles
-pressure and temperature decrease together directly proportionally
ex. if pressure halves, temperature is halved

2. Gay-Lussac’s Law

3. Gay-Lussac’s Law Problems
Answer the following questions:
What will happen to the temperature if you double the pressure of a gas?
What will happen to the pressure if you third the temperature of a gas?
What will happen to the pressure at 1.5 atm if the temperature of a gas changed from 200 K to 800 K?
What will happen to the temperature of a gas at 600 K if the pressure changes from 500 mm Hg to 250 mm Hg?
What will happen to the temperature of a gas at 27°C if the pressure changed from 100 kPa to 200 kPa?
