Properties of Seawater Water is called the universal solvent because of its ability to dissolve at least a little of virtually every substance Water is a particularly good solvent for substances held together by polar or ionic bonds Indeed the most abundant substances dissolved in seawater are ionic solids (salts such as sodium chloride)
Properties are listed as a function of temperature and salinity for the pressures P = P0 7 MPa and 12 MPa Here P0 = 0 101325 MPa for t 100 °C is the vapor pressure of seawater For P = 7 MPa and 12 MPa only the properties with pressure dependence are listed

Summary This article offers a brief overview of physical properties of seawater including its three states—liquid phase sea ice and vapor The liquid medium is a single-phase thermodynamic system which is characterized by the following physical state variables: mass volume pressure temperature and salinity
Seawater is a complex solution containing dissolved inorganic salts (3 5 ) dissolved gases and traces of dissolved organic molecules Chemical and physical exchanges at the interface between the ocean and atmosphere have profound effects on the heat budget and climate of the Earth
