Atmosphere of Pressure |
1 atm is defined as the exact equivalent of 760 mm Hg |
|
|
Avogadro's Law |
Equal volumes of gases at the same temperature and pressure contain equal numbers of molecules |
|
|
Barometer |
A device used to measure atmospheric pressure |
|
|
Boyle's Law |
The volume of a fixed mass of gas varies inversely with the pressure at constant temperature |
|
|
Charles's Law |
The volume of a fixed mass of gas at constant pressure varies directly with the Kelvin temperature |

|
Combined Gas Law |
Expresses the relationship between pressure, volume, and temperature of a fixed amount of gas |
|
|
Dalton's Law of Partial Pressure |
States that the total pressure of a gas mixture is the sum of the partial pressures of the component gases |
|
|
Diffusion |
Spontaneous mixing of the particles of two substances caused by their random motion |
|
|
Effusion |
A process by which gas particles pass through a tiny opening |
|
|
Elastic Collision |
Collision in which there is no net loss of total kinetic energy; particles bounce off of one another |
|
|
Gay-Lussac's Law |
The pressure of a fixed mass of gas at constant volume varies directly with the Kelvin temperature |
|
|
Gay-Lussac's Laws of Combining Volumes and Gases |
At constant temperature and pressure, the volumes of gaseous reactants and products can be expressed as ratios of small whole numbers |
|

Ideal Gas Constant |
The constant "R" that is used in the equation for the ideal gas law |
|
|
Ideal Gas Law |
The mathematical relationship among pressure, volume, temperature, and the number of moles of a gas |

|
Newton |
The SI unit for force |
|
|
Partial Pressure |
The pressure of each gas in a mixture |

The SI unit for pressure; the pressure exerted by a force of one Newton acting on an area of one square meter |
|
|
Pressure |
The force per unit area on a surface |
|
|
Real Gas |
A gas that does not behave according to all of the assumptions of the kinetic-molecular theory |
|
|
Standard Molar Volume of a Gas |
The volume occupied by one mole of a gas at STP; found to be 22.4 L |
