Talk:Steam

Wikipedia has an article about steam

However, this article was completely re-written. Other than the drawing of a Mollier Diagram and perhaps one or two references, there may be a sentence or two taken from the WP article. Milton Beychok 05:33, 13 November 2009 (UTC)

Non-water steam?

So non-water gas is not technically steam, right? I infer as much from the opening, but would not have defined steam as water only if someone had asked me yesterday. Should the distinction be stated in the opening somewhere? --Joe Quick 15:49, 13 November 2009 (UTC)

Forgive me for butting in. Do I understand correctly that before yesterday you thought that there exist gases, called steam, that do not consist of water molecules, H₂O? What interests me is: what sort of gases, that aren't water, did you call steam before yesterday?--Paul Wormer 15:58, 13 November 2009 (UTC)

Joe, I echo Paul's comment. If the gas is not H₂0, then it definitely is not water. It is not a matter of it being "technically" correct, it is definitely correct. Milton Beychok 16:42, 13 November 2009 (UTC)

Earlier, I was trying to think of something I would call steam that is not made up of water. I couldn't do it, but I still felt like there must be something I would have called steam that was not actually water. Is boiling also specific to water? Okay, well I know that all chemicals have a boiling point, so the answer is no, but do other substances release clouds of vapor in the process? I'd have said that steam is the vapor let off when something boils. To be clear, I'm not suggesting that steam means anything other than water, but I don't know if it is totally clear to non-scientists that other chemicals can't form steam. --Joe Quick 17:36, 13 November 2009 (UTC)

Joe, yes other chemicals may form clouds of vapors when they boil or evaporate and they may be visible, colored clouds but they are not referred to as "steam". They would simply be referred to as a gaseous cloud of chemical X. Milton Beychok 17:55, 13 November 2009 (UTC)

Steam tables and Mollier diagrams

I would move these sections to separate articles. --Daniel Mietchen 16:56, 13 November 2009 (UTC)

Daniel, I completely agree that steam tables and Mollier diagrams deserve separate article of their own where they can be discussed in much more detail. However, I still believe that this article should retain the brief discussions that I provided of them. Milton Beychok 18:03, 13 November 2009 (UTC)

Just what does making a table "sortable" meant to do? As far as I can see, clicking on those "sortable" icons simply flips the table contents vertically. Instead of listing from lower temperatures to higher temperatures, it lists the table's bottom notes at the top and then lists from the higher temperatures to the lower temperatures. Is that all it was meant to do? Is there some purpose in doing that? Milton Beychok 18:20, 13 November 2009 (UTC)
