Pressure (not to scale) 1 atm Ice II Ice I Ice V Ice III/ D Ice VII Ice VI Liquid water Gaseous water Temperature (not to scale) Figure 12-30 Phase diagram for water Point O, the triple point, is at 0.0098 °C and 4.58 mmHg. (The normal melting point is at exactly 0 °C and 760 mmHg.) The critical point, C, is at 374.1 °C and 218.2 atm. At point D the temperature is -22.0 °C and the pressure is 2045 atm. The negative slope of the fusion curve, OD (greatly exaggerated here), and the significance of the broken straight lines are discussed in the text.
