absolute temp
the total Kenetic energy =

2/3RT
diffusion =

mixing of gasses a result of random motion and frequent collison
effusion=

escape of a gas molecues from a container to aregion of vacum
Grahms Law

the rate of diffusion or effusion of a gas is inversley proportional to the sq root of it molar mass
lighter gass _____ and _____ more rapidly

diffuse and effuse
pressure =
- force applied per unit area
- force/area
boyles law
- pressure - volume relationship
- PV=k₁
Chalres (and gay) Law
- the temp-vol relation ship
- V/T
Avoadros Law
- the number of moles -vol relationship
- V=nK
PV=nRT

ideal gas equation
Daltons Law of Partial Pressure

total pressure exeted by a gas = the sum of all the partial pressure exerted by eac componet of the mixture
Mole fraction

# of moles in a componet / total moles in mixture
