It is because the liquid in the bottle is supercooled - the temperature of the liquid is below its normal freezing point, but the liquid has still not turned into a solid.
12 paź 2023 · Pure water has no impurities, so without a nucleus to kickstart the freezing process, the water becomes supercooled. This allows the water to freeze faster when exposed to an external nucleus, making the magic of "instant" ice possible.
The Mpemba effect is the name given to the observation that a liquid (typically water) that is initially hot can freeze faster than the same liquid which begins cold, under otherwise similar conditions. There is disagreement about its theoretical basis and the parameters required to produce the effect.
7 kwi 2021 · Here comes the interesting thing: I uncap the bottles, flip them upside down to empty the water, and give them a shake/twist so that it empties faster, and I noticed that some not well structured ice (it was more looking like melting snow actually) was forming almost instantaneously.
No, water cannot freeze instantly. This process takes time, and the amount of time it takes will depend on several factors, including the temperature of the environment and the amount of water being frozen.
12 mar 2024 · The Mpemba effect is a physics concept that postulates that when hot water and cold water are placed in the identical freezing environment, the hot water will freeze faster than the cold water.
17 cze 2024 · New simulations indicate that ice crystallization happens fastest — this slow-motion movie covers mere nanoseconds — when water is tuned to a critical point called the liquid-liquid transition. We learn in grade school that water freezes at zero degrees Celsius, but that’s seldom true.
