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?
Water is known to remain in the liquid state after supercooling even at temperatures as low as â (negative) 400 0 Celsius and when exposed to high-pressure conditions, supercooled water will stay in a liquid state at low temperatures of â (negative) 700 Celsius. For comparison, the freezing point of pure water in normal conditions is 0 0 Celsius.
