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?
T1 The heat of fusion of water with temperature exhibits a maximum at -17 Â°C . This strange behavior [15 ] (see right) has been determined from the variation in ice and water specific heat capacities (Cp). It is due to changes in the structuring of supercooled water.
