  2. Freezing-point depression - Wikipedia

    en.wikipedia.org/wiki/Freezing-point_depression

    Workers spreading salt from a salt truck for deicing the road Freezing point depression is responsible for keeping ice cream soft below 0°C. [1]Freezing-point depression is a drop in the maximum temperature at which a substance freezes, caused when a smaller amount of another, non-volatile substance is added.

    The correct temperature for your freezer is 0 degrees Fahrenheit—if you set it to 0 degrees (-18 degrees Celsius) and keep it fairly full, it will maintain that temperature. How to Monitor ...

  4. Aircraft deicing fluid - Wikipedia

    en.wikipedia.org/wiki/Aircraft_deicing_fluid

    Lowest operational use temperature LOUT is the lowest temperature at which a de/anti-icing fluid will adequately flow off aircraft critical surfaces and maintain the required anti-icing freezing point buffer for type II, III and IV fluid which is 7°C (13°F), and 10°C (18°F) for type I fluid below outside air temperature (OAT).

  5. Auto-defrost - Wikipedia

    en.wikipedia.org/wiki/Auto-defrost

    A defrost thermostat opens the heater circuit when the evaporator temperature rises above a preset temperature, 40°F (5°C) or more, thereby preventing excessive heating of the freezer compartment. The defrost timer is such that either the compressor or the defrost heater is on, but not both at the same time.

  6. WD-40 - Wikipedia

    en.wikipedia.org/wiki/WD-40

    WD-40's formula is a trade secret. [17] The original copy of the formula was moved to a secure bank vault in San Diego in 2018. [18] To avoid disclosing its composition, the product was not patented in 1953, and the window of opportunity for patenting it has long since closed.

  7. Calcium magnesium acetate - Wikipedia

    en.wikipedia.org/wiki/Calcium_magnesium_acetate

    Calcium magnesium acetate (CMA, with chemical formula C 12 H 18 CaMg 2 O 12 [1]) is a deicer and can be used as an alternative to road salt.It is approximately as corrosive as normal tap water, and in varying concentrations can be effective in stopping road ice from forming down to around −27.5 °C (−17.5 °F) (its eutectic temperature [2]).

  8. Potassium acetate - Wikipedia

    en.wikipedia.org/wiki/Potassium_acetate

    Potassium acetate (as a substitute for calcium chloride or magnesium chloride) can be used as a deicer to remove ice or prevent its formation. It offers the advantage of being less aggressive on soils and much less corrosive: [5] for this reason, it is preferred for airport runways although it is more expensive.

  9. Freezing - Wikipedia

    en.wikipedia.org/wiki/Freezing

    The melting point of water at 1 atmosphere of pressure is very close to 0 °C (32 °F; 273 K), and in the presence of nucleating substances the freezing point of water is close to the melting point, but in the absence of nucleators water can supercool to −40 °C (−40 °F; 233 K) before freezing.
