The formula that is used to calculate the
pressure is:
force/area
explains that pressure (atm) and
volume (L) are inversely proportional under
constant temperature and moles…. which law
Boyles Law
Boyles law formula
P1 V1 = P2 V2
explains that volume (L) and
temperature (K) are directly proportional under
constant pressure and moles… which law
Charles law
Charles Law formula
v1/t1 = v2/t2
explains that volume (L) and
moles (mol) are directly proportional under
constant pressure and temperature… what law
avogadros law
avogadros law eqn
v1/n1 = v2/n2
explains that pressure (atm)
and temperature (K) are directly proportional
under constant volume and moles… which law
Gay-Lussac’s Law
Gay-Lussac’s Law formula
p1/t1 = p2/t2
the ratio of initial
pressure (atm) and volume (L) to temperature
(K) and moles (mol) to its final state:
combined gas law
combined gas law eqn
p1v1/n1t1 = p2v2/n2t2
models and
predicts the behavior of ideal gases through 5
postulates:
kinetic-molecular theory of gassea
Particles in a gas are in what kind of motion
constant random
The combined volume of particles (gas)…
is negligable
Particles exert what kind of force on each other
none
Gas molecule collisions are completely
elastic
As pressure increases, the intermolecular forces
and molecular volume become
increasingly significant
Ideal gas law formula
pressure x volume = number of moles x gas constant x temp (K)
pressure exerted by one
type of gas in a mixture of other gases.
partial pressure
eqn for daltons law of partial pressure
pressure (total) = p1+p2+p3….
partial
pressure of each gas can be calculated from the
product of the total pressure and the mole
fraction of the gas:
p1 = mole fraction of gas 1 x pressure total
formula for gas density is:
pressure x molar mass/gas constant x temp
as the movement of gas
molecules from one container to another
through a tiny hole.
effusion
formula for Graham’s Law of Effusion,
rate of effusion gas 1/rate of effusion gas 2 = sqrt of molar mass gas 1/molar mass of gas 2
