  2. Antifreeze - Wikipedia

    en.wikipedia.org/wiki/Antifreeze

    An antifreeze mixture is used to achieve freezing-point depression for cold environments. Common antifreezes also increase the boiling point of the liquid, allowing higher coolant temperature. [1] However, all common antifreeze additives also have lower heat capacities than water, and do reduce water's ability to act as a coolant when added to ...

  3. Freezing-point depression - Wikipedia

    en.wikipedia.org/wiki/Freezing-point_depression

    In the above equation, T F is the normal freezing point of the pure solvent (273 K for water, for example); a liq is the activity of the solvent in the solution (water activity for aqueous solution); ΔH fus T F is the enthalpy change of fusion of the pure solvent at T F, which is 333.6 J/g for water at 273 K; ΔC fus p is the difference ...

  4. Fractional freezing - Wikipedia

    en.wikipedia.org/wiki/Fractional_freezing

    Fractional freezing is a process used in process engineering and chemistry to separate substances with different melting points. It can be done by partial melting of a solid, for example in zone refining of silicon or metals, or by partial crystallization of a liquid, as in freeze distillation, also called normal freezing or progressive freezing.

    Drastically dropping the temperature in your home between the night and day can leave your pipes more prone to freezing than they would be if you leave your heat on (anywhere over 55 degrees ...

  6. Freezing - Wikipedia

    en.wikipedia.org/wiki/Freezing

    Freezing is a phase transition in which a liquid turns into a solid when its temperature is lowered below its freezing point. [ 1 ] [ 2 ] For most substances, the melting and freezing points are the same temperature; however, certain substances possess differing solid-liquid transition temperatures.

  7. Supercooling - Wikipedia

    en.wikipedia.org/wiki/Supercooling

    Supercooling is the cooling of a liquid below its freezing point without it becoming solid. Freezing point depression is when a solution can be cooled below the freezing point of the corresponding pure liquid due to the presence of the solute; an example of this is the freezing point depression that occurs when salt is added to pure water.
