Abstract
A three-dimensional phase diagram for ordinary water substance, with its solid, liquid, and vapor phases, based on fitted authentic experimental data is presented. Such an authentic diagram appears not to have been presented for water before, and may improve the understanding of its phase relationships. The nature of the IAPWS-95 equations, fitted to data, is discussed.

Complexities of One-Component Phase Diagrams
Andrea Ciccioli and Leslie GlasserJournal of Chemical Education2011 88 (5), 586-591Complexities of One-Component Phase Diagrams
Andrea Ciccioli and Leslie GlasserJournal of Chemical Education2011 88 (5), 586-591For most materials, the solid at and near the triple-point temperature is denser than the liquid with which it is in equilibrium. However, for water and certain other materials, the densities of the phases are reversed, with the solid being less dense. ...
One-Component Pressure−Temperature Phase Diagrams in the Presence of Air

Julio Andrade-Gamboa, Daniel O. Mártire, Edgardo R. DonatiJournal of Chemical Education2010 87 (9), 932-936One-component phase diagrams are good approximations to predict pressure−temperature (P−T) behavior of a substance in the presence of air, provided air pressure is not much higher than the vapor pressure. However, at any air pressure, and from the ...

Ed Vitz , Kenneth S. LyleJournal of Chemical Education2008 85 (10), 1385A series of demonstrations is described that elucidate the operation of commercial fog machines by using common laboratory equipment and supplies. The formation of fogs, or "mixing clouds", is discussed in terms of the phase diagram for water and other ...
