There's an equilibrium between solid and liquid at this value.
Thiele tubes are instruments used to measure this property of compounds using capillary tubes. The purity of organic compounds like aspirin can be checked by measuring the decrease and broadening of this property. For a binary mixture, this property is minimized at the eutectic composition. For water, (*) 1.86 times the molality gives the "depression" in this colligative property, and the change in enthalpy as a material undergoes a namesake process at this value is called the heat of fusion. There's an equilibrium between solid and liquid at this value. For 10 points, give this value equal at standard conditions to zero degrees Celsius for water.
