  2. Cloud physics - Wikipedia

    en.wikipedia.org/wiki/Cloud_physics

    The range of temperatures that can give rise to icing conditions is defined according to cloud types and altitude levels: Low-level stratocumulus and stratus can cause icing at a temperature range of 0 to -10 °C. For mid-level altocumulus and altostratus, the range is 0 to -20 °C.

  3. Cork (material) - Wikipedia

    en.wikipedia.org/wiki/Cork_(material)

    Harvesting of cork from the forests of Algeria, 1930. Cork is a natural material used by humans for over 5,000 years. It is a material whose applications have been known since antiquity, especially in floating devices and as stopper for beverages, mainly wine, whose market, from the early twentieth century, had a massive expansion, particularly due to the development of several cork-based ...

  4. Dry ice - Wikipedia

    en.wikipedia.org/wiki/Dry_ice

    The density of dry ice increases with decreasing temperature and ranges between about 1.55 and 1.7 g/cm 3 (97 and 106 lb/cu ft) below 195 K (−78 °C; −109 °F). [3] The low temperature and direct sublimation to a gas makes dry ice an effective coolant, since it is colder than water ice and leaves no residue as it changes state. [4]

  5. Wegener–Bergeron–Findeisen process - Wikipedia

    en.wikipedia.org/wiki/Wegener–Bergeron...

    The Wegener–Bergeron–Findeisen process (after Alfred Wegener, Tor Bergeron and Walter Findeisen []), (or "cold-rain process") is a process of ice crystal growth that occurs in mixed phase clouds (containing a mixture of supercooled water and ice) in regions where the ambient vapor pressure falls between the saturation vapor pressure over water and the lower saturation vapor pressure over ice.

  6. Surface tension - Wikipedia

    en.wikipedia.org/wiki/Surface_tension

    Surface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible. Surface tension is what allows objects with a higher density than water such as razor blades and insects (e.g. water striders) to float on a water surface without becoming even partly submerged.

  8. 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 ...

  9. Freezing rain - Wikipedia

    en.wikipedia.org/wiki/Freezing_rain

    The red line shows how freezing rain forms, from snow through the warm layer and then into the "supercooled stage". Freezing rain is often associated with the approach of a warm front, when subfreezing air (temperatures at or below freezing) is trapped in the lowest levels of the atmosphere while warm air is advected aloft.
