1 IDEAL GAS LAW AOS 101 Section 301 9 February 2009

2 Boyle's Law Charles's Law IDEAL GAS LAW Gay-Lussac's Law

3 V = C T Charles's Law When pressure is held constant: V = Volume
T = Temperature C = Constant

4 Charles's Law This is just a special case of the Ideal Gas Law with pressure held constant: P = ρ R T P = Pressure ρ = Density R = Constant T = Temperature

5 Charles's Law This is just a special case of the Ideal Gas Law with pressure held constant: P V = R T P = Pressure ρ = Density R = Constant T = Temperature 1 V = ρ

6 Charles's Law This is just a special case of the Ideal Gas Law with pressure held constant: V R = T P P = Pressure ρ = Density R = Constant T = Temperature 1 V = ρ

7 Charles's Law This is just a special case of the Ideal Gas Law with pressure held constant: V = C T P = Pressure ρ = Density R = Constant T = Temperature R 1 C = V = ρ P

8 Charles's Law This is just a special case of the Ideal Gas Law with pressure held constant: V = C T P = Pressure ρ = Density R = Constant T = Temperature R 1 C = V = ρ P

11 P V = C Boyle's Law When temperature is held constant: P = Pressure
V = Volume C = Constant

12 Boyle's Law This is just a special case of the Ideal Gas Law when temperature is held constant: P = ρ R T P = Pressure ρ = Density R = Constant T = Temperature

13 Boyle's Law This is just a special case of the Ideal Gas Law when temperature is held constant: P V = R T P = Pressure V = Volume R = Constant T = Temperature 1 V = ρ

14 Boyle's Law This is just a special case of the Ideal Gas Law when temperature is held constant: P V = C P = Pressure V = Volume R = Constant T = Temperature 1 C = R T V = ρ

15 Boyle's Law This is just a special case of the Ideal Gas Law when temperature is held constant: P V = C P = Pressure V = Volume R = Constant T = Temperature 1 C = R T V = ρ

16 VACUUM OFF Whipped Cream (Filled with air bubbles) Sealed Container
Connected to Vacuum

17 VACUUM ON As pressure goes down, the volume of the bubbles must increase, and the whipped cream increases in size

18 P = C T Gay-Lussac's Law When density is held constant: P = Pressure
T = Temperature C = Constant

19 Gay-Lussac's Law This is just a special case of the Ideal Gas Law when the density is held constant: P = ρ R T P = Pressure ρ = Density R = Constant T = Temperature

20 Gay-Lussac's Law This is just a special case of the Ideal Gas Law when the density is held constant: P = ρ R T P = Pressure ρ = Density R = Constant T = Temperature

21 Gay-Lussac's Law This is just a special case of the Ideal Gas Law when the density is held constant: P = C T P = Pressure ρ = Density R = Constant T = Temperature R ρ = C

22 Gay-Lussac's Law This is just a special case of the Ideal Gas Law when the density is held constant: P = C T P = Pressure ρ = Density R = Constant T = Temperature R ρ = C

23 CO2 canister at room temperature

24 When CO2 is depleted from canister, the pressure inside the tank has decreased, leading to a decrease in temperature
