Boyle's law
PV=PV; constant is temperature
Avagadro's contribution to the gas laws
states that at constant pressure and temperature, the volume of a gas is directly proportional to the number of moles of the gas present
ideal gas law
PV=nRT
gas constant R
.0821 liter atmospheres/mole degree K
gas density
d=m/v
Dalton's law of partial pressure
the total pressure of a mixture of gases is the sum of the individual gas pressures
Maxwell's kinetic molecular theory of gases
treats molecules as hard spheres with no internal structure; gas molecules are in constant motion in random directions; they don't react with one another; any two gases at the same temperature will have the same average kinetic energy
gas diffusion
the gradual mixing of molecules of one gas with molecules of another by virtue of their kinetic properties
