Density of ice and water as a function of temperature. The density of water is about 1 gram per cubic centimetre (62 lb/cu ft): this relationship was originally used to define the gram. [32]
Weight of sea water: approximately 63.93 lb/cu ft at 15 °C; density of sea water: approximately 1.025 g/cu cm at 25 °C
Definitions, online calculator and figures and tables with water properties like density, specific weight and thermal expansion coefficient of liquid water at temperatures ranging 0 to 360°C (32 to 680°F).

Data chart with the density of water at different temperatures. The density of water (H 2 O) changes depending on temperature and pressure - as with other substances. The following table lists the density D of water as a function of the temperature under isobaric conditions [1, 2]:
One mole of sucrose (sugar) per kilogram of water raises the boiling point of water by 0.51 °C (0.918 °F), and one mole of salt per kg raises the boiling point by 1.02 °C (1.836 °F); similarly, increasing the number of dissolved particles lowers water's freezing point.
3 dni temu · Given the low molar mass of its constituent molecules, water has unusually large values of viscosity, surface tension, heat of vaporization, and entropy of vaporization, all of which can be ascribed to the extensive hydrogen bonding interactions present in liquid water.
