Why does water have a maximum density at +4 deg C ? Is water unique in having this peak in density not at an extremity of the temperature range of a single (i.e. liquid in the case of water) state? Is this property of water the single most important reason for life to have evolved on this planet?
The Density of pure water is 1gm/ml. The Density of sea water in the ocean (on average) is 1.025 gm/ml. The SPECIFIC DENSITY of sea water is a RATIO of the density of sea water with that of water = 1.025. The specific gravity of sea water is 1022 kg/cu.m.
