From Wikipedia, the free encyclopedia

Sea water in the Strait of Malacca

Seawater is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5%. This means that every kilogram (2.2lb), or every litre, of seawater has approximately 35 grams (1.2 oz) of dissolved salts (mostly, but not entirely, the ions of sodium chloride: Na+, Cl−). The average density of seawater at the ocean surface is 1.025 g/ml; seawater is denser than freshwater (which reaches a maximum density of 1.000 g/ml at a temperature of 4 °C (39 °F)) because of the salts' added mass. Thefreezing point of sea water decreases with increasing salinity and is about −2 °C (28.4 °F) at 35 g/l.[1]
