State:

Boyle’s Law (In words and formula) Corwin Section 11.4 p 297 Hill p169-171

The volume of a gas is inversely proportional to the pressure when the temperature remains constant.

V1P1=V2P2

Charles Law (in words and formula) Corwin Section 11.5 p 300; Hill p171-174

The volume of a gas is directly proportional to the Kelvin temperature if the pressure remains constant.

V1  =  V2

T1      T2

Gay-Lussac’s Law (in words and formula)     Section 11.6 p 302

The pressure of a gas is directly proportional to the Kelvin temperature if the volume remains constant.

P1  =  P2

T1      T2

Dalton’s Law of Partial pressures (in words and formula)  Section 11.9 p308-9

The total pressure of a gaseous mixture is equal to the sum of the individual pressure of each gas.

Ptotal =  P1  + P2  + P3 + …

Combined Gas Law Equation (write only the equation): Section 11.7 p 304

V1P1   =   V2P2

T1           T2

Ideal Gas Equation (write only the equation): Corwin Section 11.11 p 313 Hill p174-175

PV = nRT

Define: Vapor Pressure of a Liquid: Section 11.8 p 306

The vapor pressure of a liquid is the pressure exerted by the gaseous vapor above a liquid when the rate of evaporation and condensation are equal
