One component 3D phase diagram changes

The 3D phase diagram needs correcting. All occurrences of liquid appear to be misspelled Ariakalea (talk) 06:30, 11 February 2011 (UTC)

I agree that correcting the spelling of "Liquid" is needed for that diagram. I can make am working on making corrections to that image. While I'm at it, I would like to make the following changes to this diagram:

• correcting spelling of "Liquid"
• changing "Volume" to "Specific volume", which is how such diagrams are usually shown for a given compound
• eliminating the rather confusing isotherms from the diagram
• delete the "pedestal" (base) from the bottom, which might be nice and aesthetic-looking for an actual model but has no scientific or explanatory benefit in the diagram

The following change would also be good:

• shading or coloring of the phase surfaces, perhaps with different colors for each of the phases

If anybody has any comments on these ideas, let me know. H Padleckas (talk) 05:35, 13 February 2011 (UTC)

I agree with 4 of 5 suggestions, but I would retain the isotherms. I think the detailed shape of the diagram would be harder to see (understand) if all the isotherms were eliminated. Of course, if you see a way to draw isotherms which are less confusing, I have no objection.

Changing volume to specific volume is a good idea which will make the diagram more general. Then the legend will not have to specify "for fixed amount". Dirac66 (talk) 17:23, 13 February 2011 (UTC)

I have not started any work on the isotherms, the "pedestal", or the surfaces yet. Presently all the lines/curves in the 3D diagram are colored blue. To keep the isotherms, but make them less confusing with the other lines, the isotherms or the other lines can be given a different color to distinguish them.
