|
|
The pressure of each gas in a mixture
|
Partial Pressure
|
|
Dalton's law
|
The total pressure of a gas mixture is the sum of the partial pressures of the component gases.
|
|
Boyle's law
|
The volume of a fixed mass of gas varies inversely with the pressure at constant temperature.
|
|
Absolute Zero
|
The temperature -273°C, given a value of zero in the Kelvin scale.
|
|
Charles's Law
|
That the volume of a fixed mass of gas at a constant pressure varies directly with the Kelvin temperature.
|
|
Gay-Lussac's law
|
The pressure of a fixed mass of gas at a constant volume varies directly with the Kelvin temperature.
|
|
Avogadro's law
|
That equal volumes of gases at the same temperature and pressure contain equal numbers of molecules.
|
|
Ideal gas law
|
The mathematical relationship among pressure, volume, temperature, and the number of moles of a gas.
|
|
Ideal Gas Constant
|
The constant R. It's value depends on the units chosen for pressure, volume, and temperature.
|
|
Graham's law of effusion
|
That the rates of effusion of gases at the same temperature and pressure are inversely proportional to the square roots of their molar masses.
|
|
