gas laws
The gas laws
are a set of laws that describe the relationship between thermodynamic temperature
(T), pressure (P) and
volume (V) of gases. It is a loose
collection of rules developed between the late Renaissance and early
19th century.
which with the addition of Avogadro's law later gave way to the ideal gas
law:
where
(The above units are the SI ones. The law works equally well with any consistent
set of units, provided that the temperature scale is such that it is zero
at absolute zero.)
Other important gas laws include Dalton's law of partial pressures. The kinetic theory
of gases, Graham's law of effusion
and root mean
square velocity all explain how
individual molecules in a gas act and their relation to pressure, volume,
and temperature.
A gas that obeys these gas laws exactly is
known as an ideal gas
(or perfect gas). An ideal gas does not exist; however, some gases follow
the laws more closely than others given standard
conditions. |
