  2. Mpemba effect - Wikipedia

    en.wikipedia.org/wiki/Mpemba_effect

    The phenomenon, when taken to mean "hot water freezes faster than cold", is difficult to reproduce or confirm because it is ill-defined. [4] Monwhea Jeng proposed a more precise wording: "There exists a set of initial parameters, and a pair of temperatures, such that given two bodies of water identical in these parameters, and differing only in initial uniform temperatures, the hot one will ...

  3. Flash freezing - Wikipedia

    en.wikipedia.org/wiki/Flash_freezing

    As water freezes, tiny amounts of liquid water are theoretically still present, even as temperatures go below −48 °C (−54 °F) and almost all the water has turned solid, either into crystalline ice or amorphous water. However, this remaining liquid water crystallizes too fast for its properties to be detected or measured. [11]

  4. Cold shock response - Wikipedia

    en.wikipedia.org/wiki/Cold_shock_response

    A cold shock is when bacteria undergo a significant reduction in temperature, likely due to their environment dropping in temperature. To constitute as a cold shock the temperature reduction needs to be both significant, for example dropping from 37 °C to 20 °C, and it needs to happen over a short period of time, traditionally in under 24 ...

    For example, in a scenario where the actual temperature is 10 degrees but the "feels like" temperature is -5 degrees, what that really means is that the wind chill is making it feel as if the air ...

  6. Why does it feel colder than the actual temperature? Here's ...

    With high wind speeds forecasted in the state, it'll feel much colder than the actual temperature. Here's what to know about wind chill and what the term means.

  7. Leidenfrost effect - Wikipedia

    en.wikipedia.org/wiki/Leidenfrost_effect

    Initially, as the temperature of the pan is just below 100 °C (212 °F), the water flattens out and slowly evaporates, or if the temperature of the pan is well below 100 °C (212 °F), the water stays liquid. As the temperature of the pan rises above 100 °C (212 °F), the water droplets hiss when touching the pan, and these droplets evaporate ...

  8. Apparent temperature - Wikipedia

    en.wikipedia.org/wiki/Apparent_temperature

    Apparent temperature, also known as "feels like", [1] [2] is the temperature equivalent perceived by humans, caused by the combined effects of air temperature, relative humidity and wind speed. The measure is most commonly applied to the perceived outdoor temperature.

  9. Rime ice - Wikipedia

    en.wikipedia.org/wiki/Rime_ice

    Hard rime forms by rapid freezing of supercooled water under at least moderate wind conditions. The droplets freeze more or less individually, leaving air gaps. Clear ice forms by slow freezing of supercooled water. Clear ice is typically transparent and homogeneous. Its amorphous and dense structure makes it adhesive.
