Chemistry Gas Laws are laws that relate together the pressure, volume and temperature of a gas.

###### Examining the Chemistry Gas Laws

Concept #1: Chemistry Gas Laws

The Ideal Gas Law can be used to determine each of the Chemistry Gas Laws

Concept #2: Boyle's Law

Boyle's Law: Volume and Pressure are inversely proportional at constant n and Temperature.

Concept #3: Gay-Lussac’s Law

Gay-Lussac's Law: Pressure and Temperature are directly proportional at constant n and Volume.

Avogadro's Law: Volume and n are directly proportional at constant Pressure and Temperature.

Concept #5: Charles’s Law

Charle's Law: Volume and Temperature are directly proportional at constant n and Pressure.

Example #1: A 10.0 L cylinder with a movable piston contains 10.0 g of xenon gas. When an additional 10.0 g of xenongas are added the volume increases. Which Chemistry Gas Law can be used to justify this result?

Practice: A 10.0 L cylinder with a movable piston exerts 3.00 atm of pressure. What will happen to the pressure if the volume of the container increases to 20.0 L?

a) It will double

b) It will decrease by half

c) It will increase slightly

d) No change

Practice: A sealed container with a movable piston contains a gas with a pressure of 1380 torr, a volume of 820 mL and a temperature of 31°C. What would the volume be if the new pressure is now 2.83 atm, while the temperature decreased to 25°C?
