Avogadro's Law
equal volumes of gases at the same temperature and pressure contain
equal numbers of molecules
Boyle's Law
Boyle's Law states that at constant temperature and moles, pressure and
volume are inversely proportional.
Mathematically this is written as: PV = PV
Charles' Law
the law that states that for a fixed amount of gas at a constant pressure,
the volume of the gas increases as the temperature of the gas increases
and the volume of the gas decreases as the temperature of the gas
decreases
Gay-Lussac's Law
the pressure of a gas is directly proportional to the Kelvin temperature if
the volume is constant

Combined Gas Law
the relationship between the pressure, volume, and temperature of a fixed
amount of gas
Ideal Gas Law
PV=nRT
R=.0821
If 5.00 g of Gas A and 5.00 g of Gas B are mixed in the same container, and the partial
pressure of Gas B is determined to be twice that of Gas A, what do we know about the
gases?
If Gas A has half the partial pressure of Gas B, this indicates that there
are fewer moles of it at the same mass, and therefore Gas A has twice the
molar mass of Gas B
mol fraction and partial pressure
the formula for both
Amonton's Law
if the volume of a gas is held constant, increasing the temperature of the
gas increases its pressure.

Boyle's Law
in terms of KE
Volume decreased, wall area decreased = increased pressure
Avagadro's Law
in terms of KE
Container pressure constant, more gas molecules added = increased
volume
Dalton's Law
The total pressure of a mixture of gases is the sum of the individual
pressures (Ptotal=P1+P2+P3...)
The kinetic energy (KE) of a particle of mass (m) and speed (u) is given by
KE = 1/2 mu^2
The KE avg of a collection of gas molecules is also directly proportional to the temperature of
the gas and may be described by the equation
KEavg = 3/2 RT
