[edit] Original article source

I noticed that the content of this article seems very similar to the content at this site. I think the article should be rewritten if the Wikipedia article was copied from this website.--GregRM 19:23, 8 July 2006 (UTC)

Probably why it's listed as the only reference. I added the cleanup tag, it doesn't look great. 58.107.61.162 13:51, 30 July 2007 (UTC)

[edit] "Speed" and "faster" are a poor choice of words

This a quote from the lead-in paragraph:

Volatility in the context of the natural sciences is a measure of the speed at which a substance turns into a vapor from a solid or liquid state. Usually, this refers to the liquid to gas phase transition known as evaporation. Thus, volatile substances evaporate faster, and less volatile substances evaporate more slowly.

The words "speed" and "faster" are a very poor choice of words and, in my opinion, an incorrect choice.

I am revising the lead-in paragraph to read:

Volatility in the context of physics, thermodynamics and chemistry is a measure of the tendency of a substance to vaporize or how readily a substance vaporizes. At a given temperature, substances with higher vapor pressures will vaporize more readily than substances with a lower vapor pressure.
