Guys,

OK, I think I've finally gotten it. Solid, liquid, vapor, gas, right?
Well, except for sublimation? But, vapor seems to be a concentration of
numerous small LIQUID particles? OK, if that's so it really is solid,
liquid, gas, right?

Thanks for clearing that up for me, guys, and so concisly, too. :=)

Steam is in a gaseous state, only when it condenses does it form
visible water vapor.

Have you guys got a link or source to support this definition?

Gene, I've looked, but can't find one on-line that clearly defines the
definition that I can understand. My basic understanding is from a
discussion I had years ago with a scientist who corrected my
misunderstanding of this subject and it has stuck in my head. Many
people, including myself before that discussion, think of steam as being
the visible fog seen over a pot of boiling water or the exhaust from the
pistons of a steam powered locomotive. It's not steam. It's condensing
water vapor. Steam is regarded as a gas because it obeys general gas
laws whereas water vapor does not.

The elements that make water can change state between gas and liquid. Can
they also change state to solid?
Just curious,
Jim
Yes they can. See for example

or http://nautilus.fis.uc.pt/st2.5/scen...em/e00895.html

O2 melts at 55 K. Boils at 90 K
H2 melts at 14K and Boils at 20K
