Boyles law

Boyles law - states that the volume of a fixed mass of gas varies inversely with the pressure constant temperature equation - P1V1 = P2V2 P1=pressure (1st measurement) V1=volume (1st measurement) P2=pressure (2nd measurement) V2= volume (2nd measurement)

Example problem: 2atmx5L = 5atmx XL P1=2 Atm V1=5 L P2=5 Atm V2= X (2L) to solve you isolate the V2 and then solve

this picture shows the relationsship between volume and pressure. as the volume goes up the pressure drops.

Charles law

Charles law - states that the volume of a fixed mass of gas at constant pressure varies directly with the Kelvin temperature equation - V1/T1 = V2/T2 V1=volume (1st measurement) T1=temperature (first measurement) V2=volume (2nd measurement) T2=temperature (2nd measurement)

example problem: 4L/300K=V2/273K V1=4L T1=300K V2=?(3.67L) T2=273K



this picture shows the relationsship between volume and temp. as the temp rises so does the volume.

Gay Lussacs law

Gay Lussacs law - the pressure of a fixed mass of gas at constant volume varies directly with the Kelvin Temperature equation - P1/T1 = P2/T2 P1=pressure (1st measurement) T1=temperature (1st measurement) P2=pressure (2nd measurement) T2=temperature (2nd measurement)

example problem:7atm/280K=P2/273K P1=7atm T1=280K P2=?(6.82atm) T2=273K



this picture shows the relationship between the pressure and temp. as the pressure goes up so does the temp

Combined gas law

Combined Gas law - expressed the relationship between pressure, volume and temperature of a fixed amount of gas equation - P1V1/T1 = P2V2/T2 P1=presure (1st measurement) V1=volume (1st measurement) T1=temperatre (1st measurement) P2=pressure (2nd measurement) V2=volume (2nd measurement) T2=temperature (2nd measurement)



this shows the relationship btween volume pressure and temp. as the volume and pressure go up so does the temp

Daltons law

Daltons law - when a gas mixture lets out pressure, it is the sum of all of the partial pressures equation - P1+P2 =P total P1=pressure 1 P2=pressure 2 P total=pressure total



this shows the relationship between pressures. as one pressure goes up so does the other.

Ideal Gas law

Ideal gas law - when the gas is in a hypothetical state equation - PV=nRT P=absolute pressure of the gas V=volume of the gas n=number of moles in the gas R=universal gas constant T=absolute temperature
