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 âboiling temperatureâ of water at a given pressure is a saturation temperature â the temperature at which water vapour and liquid are both stable (at that pressure). It is not exactly the temperature at which water boils, unless the water is heated so slowly (and mixed so well) that no bubbles ever form, and all the boiling is actually evaporation from the surface.
