The Five Gas Laws

Charle's Law

Gay- Lussac's

Law

V1/T1 = V2/T2

• Pressure must be constant, direct relationship.
• If you microwave a marshmallow, the marshmallow will inflate because as the temperature increases, the volume of the air bubbles increase.
• At 25 degrees celsius, the volume of a gas is 56 mL, however, the temperature is increased to 50 degrees celsius. What is the new volume?

P1/T1 = P2/T2

• Volume and moles of gas must be constant.
• If you freeze a balloon, the balloon will deflate because as the temperature lowers, the pressure lowers.
• At 25 degrees celsius, the pressure is 356 mm Hg, however, the temperature is increased to 50 degrees celsius. What is the new pressure?

Boyle's Law

P1/T1 = P2/T2

• Volume must be constant.
• If you freeze a balloon, the balloon will deflate because as the temperature lowers, the pressure lowers.
• At 25 degrees celsius, the pressure is 356 mm Hg, however, the temperature is increased to 50 degrees celsius. What is the new pressure?

The Five Gas Laws

And Finally

The Combined

Gas Laws

Avogadro's Law

V1/n1 = V2/n2

• Pressure must be constant.
• If you freeze a balloon, the balloon will deflate because as the temperature lowers, the pressure lowers.
• There is 3.5 moles of NaCl in a 16 liter beaker, however, the NaCl is moved to a to 24 liter beaker. How many moles is in the beaker?

P1/T1 = P2/T2

• Volume must be constant.
• If you freeze a balloon, the balloon will deflate because as the temperature lowers, the pressure lowers.
• At 25 degrees celsius, the pressure is 356 mm Hg, however, the temperature is increased to 50 degrees celsius. What is the new pressure?
