Water (data page)

Further comprehensive authoritative data can be found at the NIST Chemistry WebBook page on thermophysical properties of fluids.

The data that follows was copied and translated from the German language Wikipedia version of this page (which has moved to here).

In the following tables, values are temperature-dependent and to a lesser degree pressure-dependent, and are arranged by state of aggregation (s = solid, lq = liquid, g = gas), which are clearly a function of temperature and pressure.

[22] This applies to: In the following table, material data are given for standard pressure of 0.1 MPa (equivalent to 1 bar).

The following table is based on different, complementary sources and approximation formulas, whose values are of various quality and accuracy.

Over liquid water For temperature range: 173.15 K to 373.15 K or equivalently −100 °C to 100 °C Over ice For temperature range: 173.15 K to 273.15 K or equivalently −100 °C to 0 °C At triple point An important basic value, which is not registered in the table, is the saturated vapor pressure at the triple point of water.
