1. GAS LAWS

2. CHARLES'S LAW Jacques Charles Invented hydrogen balloon Collected data on the relationship between the temperature and volume of gases

3. CHARLES’S LAW States that if pressure is constant, then the volume should increase with a increase in temperature Formula: V 1 = V 2 T 1 T 2 T 1 and V 1 represent the temperature before the change T 2 and V 2 represent the temperature after the change TEMPERATURE MUST BE EXPRESSED IN KELVIN!!!!!!!

4. CHARLES’S LAW Directly proportional- both variables will increase or decrease at the same rate.

5. ABSOLUTE ZERO Temperature of 0 K is called absolute zero Charles calculated that if you extend the line to see what the temperature would be for a substance to have a volume of 0 mL, the temperature would have to be 0 K No scientist has ever reach 0 K in a laboratory, but some have gotten close

6. BOYLE’S LAW Robert Boyle is thought to be the first modern chemist Observed the affects that volume has on pressure

7. BOYLE’S LAW States that if temperature of a gas is constant, then if the volume decreases the pressure will increase Formula: P 1 V 1 =P 2 V 2 P 1 and V 1 represent the pressure and volume before the change P 2 and V 2 represent the pressure and volume after the change Units for pressure can include millimeters of Mercury (mmHg), atmospheric pressure (atm), and Pascal (Pa)

8. BOYLE’S LAW Inversely proportional- as one variable doubles the other variable halves

9. COMBINED GAS LAW Combining Boyle’s law and Charles’s law creates the combined gas law Formula: P 1 V 1 = P 2 V 2 T 1 T 2
