# Ideal Gas Law

The ideal gas law is the equation of state of a hypothetical ideal gas. It is a good approximation to the behaviour of many gases under many conditions, although it has several limitations. It was first stated by Émile Clapeyron in 1834 as a combination of Boyle's law and Charles's law. It can also be derived from kinetic theory, as was achieved (apparently independently) by August Krönig in 1856 and Rudolf Clausius in 1857.

### Famous quotes containing the words law, ideal and/or gas:

The end of law is not to abolish or restrain, but to preserve and enlarge freedom. For in all the states of created beings capable of laws, where there is no law, there is no freedom.
John Locke (1632–1704)

Some day the soft Ideal that we wooed
Confronts us fiercely, foe-beset, pursued,
And cries reproachful: “Was it then my praise,
And not myself was loved? Prove now thy truth;
I claim of thee the promise of thy youth.”
James Russell Lowell (1819–1891)

Papa died in the gas chamber,
slipping blue as an undressed minnow,
gulping in the shower to wash the Jew off him.
Anne Sexton (1928–1974)
