Water has a very high specific heat capacity of 4184 J/(kg·K) at 20 °C (4182 J/(kg·K) at 25 °C) —the second-highest among all the heteroatomic species (after ammonia), as well as a high heat of vaporization (40.65 kJ/mol or 2257 kJ/kg at the normal boiling point), both of which are a result of the extensive hydrogen bonding between its ...

[54] [55] The density of ice is 917 kg/m 3 (57.25 lb/cu ft), an expansion of 9%. [56] [57] This expansion can exert enormous pressure, bursting pipes and cracking rocks. [58] In a lake or ocean, water at 4 °C (39 °F) sinks to the bottom, and ice forms on the surface, floating on the liquid water.

However, a common temperature and pressure in use by NIST for thermodynamic experiments is 298.15 K (25 °C, 77 °F) and 1 bar (14.5038 psi, 100 kPa). [4] [5] NIST also uses 15 °C (288.15 K, 59 °F) for the temperature compensation of refined petroleum products, despite noting that these two values are not exactly consistent with each other.
The density is usually on the order of 1000 kg/m^3, i.e. that of water. ... Where data points are unavailable for 25 °C or 1 atmosphere, values are given at a nearby ...
