(a) The density of water at 0oC is very nearly 1000 kg/m3 (it is actually 999.84 kg/m3), whereas the density of ice at 0oC is 917 kg/m3. Calculate the pressure necessary to keep ice from expanding when it freezes, neglecting the effect such a large pressure would have on the freezing temperature. (This problem gives you only an indication of how large the forces associated with freezing water might be.) (b) What are the implications of this result for biological cells that are frozen?
