  2. Thermocline - Wikipedia

    en.wikipedia.org/wiki/Thermocline

    As the temperature continues to drop, the water on the surface may get cold enough to freeze and the lake/ocean begins to ice over. A new thermocline develops where the densest water (4 °C (39 °F)) sinks to the bottom, and the less dense water (water that is approaching the freezing point) rises to the top.

  3. 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 ...

    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 ...

  7. Flash freezing - Wikipedia

    en.wikipedia.org/wiki/Flash_freezing

    One can therefore observe a delay until the water adjusts to the new, below-freezing temperature. [8] Supercooled liquid water must become ice at -48 C (-55 F), not just because of the extreme cold, but because the molecular structure of water changes physically to form tetrahedron shapes, with each water molecule loosely bonded to four others. [9]

  8. Effect of Sun angle on climate - Wikipedia

    en.wikipedia.org/wiki/Effect_of_Sun_angle_on_climate

    At fixed latitude, the size of the seasonal difference in sun angle (and thus the seasonal temperature variation) is equal to double the Earth's axial tilt. For example, with an axial tilt is 23°, and at a latitude of 45°, then the summer's peak sun angle is 68° (giving sin(68°) = 93% insolation at the surface), while winter's least sun ...

    While many bulk wines use screw caps -- which is likely where the stigma originated -- a screw cap is by no means and indicator of the quality of your wine.
