Dalton’s Law of Partial Pressure
if you have a mixture of gases, the total pressure equals the sum of individual pressures
Boyle’s Law
pressure and volume are inversely related
equation for pressure and volume
P1V1 = P2V2
charles’ law
volume and temperature are directly related
equation for volume and temperature
they go up and down at same time
what must the temperature be in?
kelvin
Gay-Lussac’s Law
pressure and temperature are directly related
equation for pressure and temperature
P1/T1 = P2/T2, P1T2 = P2T1
combined gas law
P1V1/T1 = P2V2/T2, P2V2T1 = P1V1/T2
GL’s law of combining gas volumes
at constant temperature and pressure, volumes of gaseous reactants and products can be expressed as whole number ratios
Avogadro’s Law
if two gases have the same temperature, pressure, and volume then moles/molecules are the same
standard molar volume of a gas
at STP - 0*C and 1 atm
1 mol gas
22.4L
ideal gas law
PV = nRT
