The enthalpy of fusion of mercury is 2.292 kJ mol−1 at its normal freezing point of 234.3 K; the change in molar volume on melting is +0.517 cm3 mol−1. At what temperature will the bottom of a column of mercury (mass density 13.6 g cm−3) of height 10.0 m be expected to freeze? The pressure at a depth d in a fluid with mass density ρ is ρgd, where g is the acceleration of free fall, 9.81 m s−2.
