3. Charles's Law • When pressure is held constant: V = C T 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

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. Gay-Lussac's Law • When density is held constant: P = C T 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
