Volume of a given mass of gas varies inversely with pressure at constant temperature P1V1=P2V2 


Volume of a given gas varies directly at the Kelvin temperature wit the gas pressure remaining constant V1T2=V2XT1 


Used to calculate simultaneous changes in temperature, pressure, and volume of a constant gas P1V1T2 X P2V2T1 

Dalton’s Law of Partial Pressures 

Total pressures of a gas in a system is the sum of partial pressures of each component gas Pt=P1+P2+P3 When gas is collected w/ water Pgas= PtPh2o 

Graham’s Law of Diffusion 

rate 1/rate 2= Square root (MM2/MM1) 


PV=nRT M(molar mass)=dRT/P D(density)= MP/RT 



If pressure is increased at a constant rate 

Temperature and Volume are decreased 

If temperature is increased at a constant rate 

Pressure and Volume are increased
