The temperature of a typical laboratory freezer unit is −20 oC. If liquid water in a completely- filled, closed container is placed in the freezer, estimate the maximum pressure developed in the container at equilibrium. The enthalpy of fusion of water may be taken as 333.4 kJ kg-1, independent of temperature and pressure, and the densities of ice and liquid water at −20 oC are 0.9172 and 1.00 g cm-3, respectively.
