PLEASE use the above + tab to enter a new comment. That provides you a form in which to first enter a Subject and then enter the new comment. Please sign the comment with four tildes like this ~~~~. That automatically signs it with your user name, the date and the time. The form automatically provides subject and enters them in the Table of Contents which will appear below after four comments are posted. The form also automatically posts new comments below any previous comments (which is where they belong).

The first responder to someone's new comment should enter the response just beneath the new comment (instead of using the above + tab) and indent the response by starting with a colon like this :. Any second responder, indent further by starting with two colons like this :: and any third responder, start with three colons like this ::: and so forth. If we don't follow these practices, the result is jumbled mess.

The ideal gas law was initialized by Robert Boyle who formulated in 1662 Boyle's law, which states that the volume of a sample of gas at a given temperature varies inversely with the applied pressure, or V = constant / p (at a fixed temperature and amount of gas). In 1699, Guillaume Amontons formulated what is now known as Amontons' law, p = constant / T.

At the end of the 18th century and the beginning of the 19th century, Jacques Alexandre César Charles' experimented (around 1780) with hot-air balloons, and additional contributions by John Dalton (1801) and Joseph Louis Gay-Lussac (1808) showed that a sample of gas, at a fixed pressure, increases in volume linearly with the temperature, i.e. V / T is constant. Because Boyle and Gay-Lussac published their findings, the ideal gas law is known in some countries as the Boyle-Gay-Lussac law.

Extrapolation of the volume/temperature relationship of ideal and many real gases to zero volume crosses the T-axis at about −273 °C. This temperature is defined as the absolute zero temperature. Since any real gas would liquefy before reaching it, this temperature region remains a theoretical minimum.

In 1811 Amedeo Avogadro re-interpreted Gay-Lussac's law of combining volumes to state Avogadro's law : equal volumes of any two gases at the same temperature and pressure contain the same number of molecules.

With hindsight, Boyle-Gay-Lussac's law, Amontons' law and Avogadro's law all turned out to be special cases of the ideal gas law.
