1 atm= |
760 mmHg 760 torr |
|
|
Boyle's Law |
at constant temp. the volume of a fixed mass of gas is inversely proportional to the pressure |
|
|
Charle's Law |
at constant pressure, the volume of a fixed mass of gas is directly proportional to the kelvin temp. |
|
|
Absolute zero |
lowest possible temperature; no motion; no volume |
|
|
V/T = |
constant |
|
|
Amonton's Law |
at constant volume, the pressure of a fixed amount of gas is directly proportional to the kelvin temp |
|
|
P/T= |
constant |
|
|
Avogrado's Law |
equal volumes of different gases at same temp and pressure contain the same amount of gas |
|
|
standard temp and pressure = |
1 atm (760 torr) and 0 degrees (273 K) |
|
|

|
Density of gas is |
directly proportional to pressure inversely proportional to temp directly prop. to molar mass |
|
|
Dalton's Law of Partial Pressure |
pressure of a mixture of gases is the sum of the partial pressures exerted by each gas |
|
|
Partial pressure |
pressure exerted by each individual gas in a mixture |
|
|
Mole fraction |
Xa= moles of gas A/total # of gas moles in mixture |
|
|
Diffusion |
movement of a gas through another gas |
|
|
Effusion |
movement of a gas through a pinhole |
|
|
Graham's Law |
The rate of effusion (diffusion) of a gas is inversely proportional to the square root of its molar mass |
|
|
rateA/rateB= |
Sq. root of molar mass B/molar mass A |
