The ideal gas law, also called the general gas equation, is the
|
|
equation of state of a hypothetical ideal gas. It is a good approximation
|
|
of the behavior of many gases under many conditions, although it has
|
|
several limitations. It was first stated by Benoît Paul Émile Clapeyron
|
|
in 1834 as a combination of the empirical Boyle's law, Charles's law,
|
|
Avogadro's law, and Gay-Lussac's law.[1] The ideal gas law is often written
|
|
in an empirical form:
|
|
------------
|
|
| PV = nRT |
|
|
------------
|
|
P = Pressure (Pa)
|
|
V = Volume (m^3)
|
|
n = Amount of substance (mol)
|
|
R = Universal gas constant
|
|
T = Absolute temperature (Kelvin)
|
|
