Boyle’s Law
Pressure is inversely related to volume
P1V1=P2V2
Charles’s Law
Volume is directly proportional to temperature
V1/T1=V2/T2
Amonton’s Law
Pressure is directly proportional to temperature
P1/T1=P2/T2
Combined Gas Law
P1V1/T1=P2V2/T2
Avogadros Law
V1/n1=V2/n2
Volume of one mole of any gas at STP
22.4 L
Units of pressure
SI units=Newton/meter²=1 Pascal (Pa)
1 standard atmosphere (1 atm)=101,325 Pa
1 atm=760 mm Hg=760 torr
Gas behavior at standard conditions
Standard temperature and pressure (STP) = 1 atm (pressure) and 0 C (273.15 K)
Standard molar volume of 1 mol = 22.4L
Ideal gas law
PV=nRT
P=pressure in atm
V=volume in L
n=moles of gas
R=ideal gas constant (0.08206 L-atm/mol-K)
T=temperature in K
