It has been speculated that Amonton was the first to note that Pressure was in direct relationship to Temperature. Should this be added to this article, noting that the Gay-Lussac Law is sometimes refered to as Amonton's Law? Dreamm 00:24, 15 December 2006 (UTC)
I have edited the clarification about the name from "Amonton's law" to "Amonton's law of Pressure-Temperature" in order to emphasize the difference between this law and other laws formulated by Amonton about friction (see http://en.wikipedia.org/wiki/Guillaume_Amontons#Amontons.27_Laws_of_Friction). Besides I have added some bibliographic support about the date of the discovery and/or publication of this work.George Rodney Maruri Game (talk) 18:37, 16 July 2010 (UTC)
Add a Graphic?
Should there be a simple graphic that shows the relationship between pressure and temperature (as pressure increases, temperature increases)?
- I agree. An additional illustration to show the relationship using idealized hard spheres would also be nice.-- Beland 07:01, 7 April 2007 (UTC)
No name? Pressure law? Maybe not Gay-Lussac's law
I was taught at high school that this law is not named after anyone, and is normally called the "pressure law". Here is what I have found at http://hypertextbook.com/physics/thermal/gas-laws/
The pressure of a gas is directly proportional to its temperature when volume is constant. Symbolically …
P ∝ T
An isochoric process is one that takes place without any change in volume.
This relationship doesn't really have a name, but I have heard it called the "pressure law" or (mistakenly) "Gay-Lussac's law".
The basic gas law relationships … The pressure of a gas is inversely proportional to its volume when temperature is constant. This relationship is known as Boyle's law or Mariotte's law. The volume of a gas is directly proportional to its temperature when pressure is constant. This relationship is known as Charles' law or Gay-Lussac's law. The pressure of a gas is directly proportional to its temperature when volume is constant. This relationship is not associated with any particular scientist.

Gay-Lussac's Law is *Not* the Pressure-Temperature Law
Wei Cheng is correct. The pressure-temperature law has been misidentified as Gay-Lussac's law for years. You will not find any original references to it as such and only chemistry texts and documents that cite chemistry texts incorrectly call it Gay-Lussac's law.
Gay-Lussac's law is the law of combining volumes. The volume-temperature law is identified as either Charles' law or Gay-Lussac's law. Historically, it was originally called Gay-Lussac's law until some prior experimental work led to it being associated with Charles. There is disagreement as to whether Gay-Lussac or Charles' should receive priority. Books I've read state that the volume-temperature law is called Gay-Lussac's in some regions of the world and Charles' law in other regions.
Textbooks often use other textbooks as references and this is the reason this error continues to propagate.
- Technically speaking, this sentence is incorrect: "though it is more usually applied to his law of combining volumes, the first listed here." It is more properly applied, but that doesn't mean it is more often applied today. I think if you asked many chemists which one is Gay-Lussac's law, most would pick the latter.

Why the hell are the units given in atmospheres? The SI units of pressure are Pascals.
NEED HELP ADDING ANIMATION
I've got the animation requested for this page, in the same format as Boyle's Law and Charles' Law. Problem is, I've been trying to read through the information on how to add pictures to wikipedia, and I really can't understand a thing. If somebody who knows how to add pictures could contact me so I can send them the animation, it'd be great!! - Sniffity — Preceding unsigned comment added by 2001:1388:803:A03E:683C:9381:FE3:72CB (talk) 03:52, 17 December 2014 (UTC)
