It is possible to obtain super-cooled water, which is water below its normal freez- ing temperature by carefully cooling very pure water. Super-cooled water is in a meta-stable state which without warning can spontaneously change to an ice-water mixture in a true equilibrium state. The super-cooling process is reversible, but the spontaneous change is not. What is the change in entropy when 1.0 g of water at -8.0 °C spontaneously changes to an ice-water mixture?
