Pressure-Temperature Gas Law - name?

We usually teach divers that there is a gas law which explains that the pressure inside a diving cylinder increases as the temperature increases. This leads to the advice not to put full cylinders near a source of heat or in direct sunlight - the fear being that the cylinder may overpressure with unpleasant consequences. In addition, this law explains why the pressure of a "hot-filled" cylinder may drop noticeably after it has cooled down.

However, I've never been convinced of a consensus on the name of the P-T gas law. I've seen it described as "Charles' Law" - which it certainly isn't (that's the V-T gas law); and often as Gay-Lussac's second law. However, G-L (in 1802) seems to have refined earlier work and formalised it (by declaring direct proportionality between volume and absolute temperature). The earliest expression of the law which says "pressure increases as temperature increases" seems to be ascribed to Guillaume Amontons who created a thermometer based on his discovery in 1695.

So, what's the best name for the P-T Law? I've used Amontons' Law in the article, but would like to see if others prefer an alternative. --RexxS (talk) 19:12, 8 July 2008 (UTC)[reply]

B-Class review

B	The article is suitably referenced, with inline citations. It has reliable sources, and any important or controversial material which is likely to be challenged is cited. Any format of inline citation is acceptable: the use of <ref> tags and citation templates such as `{{cite web}}` is optional. ~~Uncited section needs refs, but should be easy.~~Now adequately cited. Y The article reasonably covers the topic, and does not contain obvious omissions or inaccuracies. It contains a large proportion of the material necessary for an A-Class article, although some sections may need expansion, and some less important topics may be missing. Coverage of most important aspects from a diver training perspective. Should be OK. Y The article has a defined structure. Content should be organized into groups of related material, including a lead section and all the sections that can reasonably be included in an article of its kind. Appropriate structure exists and supports content well. Looks good enough. Y The article is reasonably well-written. The prose contains no major grammatical errors and flows sensibly, but it does not need to be "brilliant". The Manual of Style does not need to be followed rigorously. Looks OK. Y The article contains supporting materials where appropriate. Illustrations are encouraged, though not required. Diagrams and an infobox etc. should be included where they are relevant and useful to the content. ~~Currently no images. It should be possible to find something appropriate from linked articles.~~ Images not great but will do until better can be found. Y The article presents its content in an appropriately understandable way. It is written with as broad an audience in mind as possible. Although Wikipedia is more than just a general encyclopedia, the article should not assume unnecessary technical background and technical terms should be explained or avoided where possible. Looks OK. Y

~~Not yet. Needs more refs, and if possible some images.~~OK now, Upgrading to B-class • • • Peter (Southwood) ^(talk): 12:22, 13 December 2016 (UTC)[reply]
