Anonymous users2024-02-09Absolute zero is a degree, i.e., 0 Kelvin. This is the lowest limit of a temperature, which can only be approached infinitely and cannot be reached!! At this temperature, the movement of the molecules will stop, so it is impossible to get any lower than this, so theoretically the lowest temperature of ice is absolute zero!
Although this is not possible at the moment, it can be ...... in theory(If the landlord doesn't believe that absolute zero is impossible and believes cjj96123, you can ask "Why can't absolute zero be reached?") The answer is naturally clear).
Hehe, hope it helps, o(o!
Add: To CJJ96123, "Scientists are cooling down to this temperature, and they find that it can't go down anymore." "When have you ever seen a scientist drop to this temperature, big brother!
The current level of scientific research is absolutely impossible to reach absolute zero, but it can be infinitely close to it, such as 20 billionths of a billion higher than absolute zero, absolute zero is microscopically speaking, molecules and/or atoms are not understood inside the matter, and the difficulty of doing this can be imagined! And from the nature of this definition, absolute zero is impossible to achieve in any experiment, but it has reached low temperatures within one millionth degree above absolute zero. Don't just mess around, like scientists are cooling down to this temperature, and find that they can't go down anymore.
Conclusion.

Anonymous users2024-02-08Big brother, water is ice below freezing, and there is no ice with the lowest temperature. You might be asking about absolute zero, which is the absolute minimum temperature, and it is. Any object can drop to this temperature.
It is the lowest temperature in the universe (not the lowest temperature that can be reached experimentally, don't get it wrong), and it is practical, not theoretical. Scientists are cooling down to this temperature, and they find that it can't go any further. There is one also called Kelvin, that is, 0 k is read as zero Kelvin, which is an international unit, for example, the melting point of water is, and it can also be approximated, -273

Anonymous users2024-02-07As long as the temperature of the ice cube can vary from degrees to 0 degrees at atmospheric pressure, H2O appears in a solid state at this temperature range.
Ice water mixture.
The temperature is 0°, so if you want to cool down again, you must freeze all the water first, and there will be no water below 0°. When the water is completely frozen, the temperature of the ice can continue to drop until it reaches ambient temperature.
Melt. Ice is the solid form of water in nature, and the temperature is above zero degrees Celsius under atmospheric pressure.
, the ice will begin to melt and turn into liquid water. A Japanese research team found that when the ice began to melt, it was a molecule of water inside the crystal.
The beginning of the transition from crystallization is an opportunity to help clarify the mechanism of structural changes in aqueous proteins.
When the ice is illuminated with strong light such as electric lamps, the inside of the ice melts, and the shape of snow crystals called "ice flowers" emerges. From the Japan Institute of Molecular Sciences and Okayama University.
In order to investigate the phenomenon of ice melting from the inside, researchers used a computer to calculate what happens to ice made up of about 1,000 water molecules when it is heated.

Anonymous users2024-02-06The temperature intensity of the ice is less than 0 °C, and the minimum temperature is infinitely close to -273 °C (absolute zero.
Because of the ice-water mixture.
The temperature is 0°C, and the ice-water mixture continues to freeze into ice cubes with no flowing moisture, then the temperature will be below 0°C.
What is the temperature of the ice
At 0°C, the ice-water mixture is in a special state, and the premise of water freezing is that it must reach the water's freezing point.
However, absolute zero is thermodynamic.
The minimum temperature of absolute zero is unattainable and is only the theoretical lower limit of repentance.
Water freezes at 0°C, which is denser than ice, and is denser at 4°C.

Anonymous users2024-02-05The temperature of the ice is below 0 and the minimum temperature is infinitely close to -273 (absolute zero). Because the temperature of the mixture is 0, the mixture continues to freeze into cubes of ice with no flowing water, so the temperature will be below 0.
At 0, the ice-water drain mixture is in a special limb search state, and the premise of water freezing is that it must reach the freezing point of the water.
However, absolute zero is the lowest temperature in thermodynamics, and absolute zero is unattainable and is only a theoretical lower limit.
Water freezes at 0, which is denser than ice, and is highest at 4.

At 0, the ice-water rubber carrier is in a special state, and the premise of water freezing is that it must reach the freezing point of the water.
However, absolute zero is the lowest temperature in thermodynamics, and absolute zero is unattainable and is only the lower limit of the beam grinding theory.
Water freezes when swimming in J0, and the density of water is greater than that of ice, and the density of water is maximum at 4.
The average annual temperature in the Antarctic continent is minus 25 degrees. The average annual temperature in the coastal areas of Antarctica is around minus 17 20 degrees; In the inland areas, the average annual temperature is minus 40 to 50 degrees; The East Antarctic Plateau is the coldest, with an average annual temperature as low as minus 57 degrees. The lowest temperature ever observed on Earth was minus degrees Celsius in July 1983 at the Antarctic Observatory in New Zealand.
Zebrafish. Breeding temperature.
Zebrafish breed at a temperature of 25 degrees Celsius. >>>More
The choice of water depth is very important for fishing, and I have always believed that the first factor to consider when choosing a fishing position is the depth of the water. The main factors affected by water depth are: pressure, oxygen content, and water temperature. >>>More
Meteorologically, 20 o'clock (Beijing) is the daily boundary, that is, from 20 o'clock today to 20 o'clock tomorrow is a day. However, the daily maximum temperature refers to the temperature from 02 o'clock to 02 o'clock, and the daily maximum temperature observation time is 02 o'clock, and the meter is adjusted after the observation data (that is, the maximum temperature table is restored), and the daily minimum temperature is the minimum temperature value within 24 hours between 14 o'clock and 14 o'clock, and the meter is adjusted after 14 o'clock observation. Usually the daily maximum temperature occurs during the day, mostly in the afternoon, and usually the minimum temperature occurs at night, mostly in the second half of the night, but there are unusual times, especially when there is an invasion of cold air or a sudden and violent rise in temperature.
The current background temperature of the universe is about 3 K, which is about Celsius. The quest for absolute zero has always been ongoing, and the lowest temperature ever reached is about, almost absolute. However, humans will never be able to cool down to degrees Celsius artificially, so the universe should not be able to reach this temperature (although its background temperature is still decreasing, like cutting an apple in half, then halving, and then halving, but it can never be cut without it), so let alone below this temperature.
