A phase diagram shows the preferred physical states of matter at different temperatures and pressures. This phase diagram shows these states for water. Critical points, triple points, and ice phase processes are defined and illustrated as a function of pressure and temperature. The diagram is accompanied by a set of tables that give detailed thermodynamic data for the triple points and structural/crystallographic ... Full description.
