Boyle's Law |
Held constant: temperature and moles of gas. Varied: pressure and volume. If pressure increases, volume decreases. If pressure decreases, volume increases.
P1V1=P2V2 |
|
|
Charle's Law |
Held constant: pressure and the moles of gas. Varied: temperature and volume.
As temperature increases, volume increases. As temperature decreases, volume decreases.
V1/T1=V2/T2 |
|
|
Gay-Luusac's Law |
Held constant: volume and the number of moles. Varied: pressure and temperature.
As temperature increases, pressure increases. As temperature decreases, pressure decreases.
P1/T1=P2/T2 |
|
|
Avogadro's Law |
Held constant: pressure and temperature. Varied: volume and number of moles.
Gases at the same pressure and temperature with the equal volumes will have the same number of moles.
V1/n1=V2/n2 |
|
|
Combined Gas Law |
P1V1/T1=P2V2/T2 |
|
|
Ideal Gas Law |
Constant: R PV=nRT

Gas at STP |
T: 273K P: 1 atm |
|
|
R |
T: 273K P: 1 atm n: 1 mole V: 22.4 L (1atm)(22.4L)/(1mole)(273k) = .0821 L(atm)/mol(K) |

|
Dalton's Law of Partial Pressure |
The total pressure of a mixture of gases is equal to the sum of the individual gas pressures
PT=PA+PB+PC+... |
|
|
Atmospheric Pressure |
1atm = 760 torr |
