1.3 Exercise 19

The density of water at $0 ° \text{C}$ is very nearly $1000 \text{kg}/\text{m}^{3}$ (it is actually $999.84 \text{kg}/\text{m}^{3}$), whereas the density of ice at $0 ° \text{C}$ is $917 \text{kg}/\text{m}^{3} .$ 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.)
