|
|
the volume if a fixed quantity of gas maintained at a constant temperature is inversely proportional to the pressure.
|
Boyle's law
|
|
|
The volume of a fixed amount of gas maintained at a constant pressure is .directly proportional to its absolute temperature
|
Charles's law
|
|
|
Equal volumes of gases at the same temperature and pressure contain equal numbers of molecules
|
Avogadro's hypothesis
|
|
|
The volume of a gas maintained at constant temperature and pressure is directly proportional to the number of moles of the gas.
|
Avogadro's law
|
|
|
A hypothetical gas whose pressure, volume, and temperature behavior is completely described by the ideal-gas equation.

|
|
The pressure exerted by a particular component of a mixture of gases
|
Partial Pressure
|
|
|
A dimensionless number that expresses the ratio of the number of moles of one component to the total number of moles in the mixture.
|
Mole fraction
|
|
|
Developed over a period of about 100 years, culminating in 1857 when Rudolf Clausius published a complete and satisfactory form of the theory.
|
Kinetic-molecular theory
|
|
|
This quantity is the speed of a molecule possessing average kinetic energy.
