Combined gas law
(P1V1)/(n1T1) = (P2V2)/(n2T2)
boyle's law
V=1/P
charles's law
V/T
amontons's law
P/T
Ideal gas law
PV=nRT or V={nRT}/{P}
The density of a gas is --------- proportional to its molar mass.
directly
The density of a gas is ------------- proportional to the temperature
inversely
Gases mix ------------- in any proportions.Each gas in a mixture behaves as if--------------
homogeneously
it were the only gas present.
Dalton’s Law of Partial Pressures
Ptotal = P1 + P2 + P3 +
Postulates of the Kinetic-Molecular Theory
Postulate 1: Particle Volume
Because the volume of an individual gas particle is so small compared to the volume of
its container,
the gas particles are considered to
have mass, but no volume.
Postulates of the Kinetic-Molecular Theory
Postulate 2: Particle Motion
Gas particles are in constant, random, straight-line motion
except when they collide with each
other or with the container walls.
Postulates of the Kinetic-Molecular Theory
Postulate 3: Particle Collisions
Collisions are elastic therefore the total kinetic energy (Ek) of the particles is constant.
If you double the temperature, what happens to the volume?
A = It doubles
Graham’s Law of Effusion
The rate of effusion of a gas is inversely related to the square root of its molar mass
1/sqrt{M}
