Under what circumstances will the solution freeze at temperatures above 0 degrees Celsius?

As common sense, it is known that the freezing point of water is zero degrees Celsius. But a team of researchers in South Korea has found that at 20 degrees Celsius, water can also condense into ice.

Some scientists have previously proposed that if a strong enough electric field is applied to water, then the water may condense into a solid at room temperature, forming "warm ice". Kang Hoon, a scientist at Seoul University, and his colleagues tested this idea by chance.

The team was using a scanning tunneling microscope to observe how electrons pass through a layer of water to reach the electrodes under the water film, Science News Weekly 29** said. Electronic readings showed that the charged metal tip of the scanning tunneling microscope was hindered as it vibrated up and down in the water film.

For this discovery, the research team believes that the water molecules below the tip of the falling metal have instantly solidified and formed an obstacle to the tip. They explain that as the tip keeps dropping and the closer it is to the electrode, the electric field between the two increases. When a critical point is reached, which is about 2 molecules of water, the water is transformed into a solid form by an electric field.

The specific transformation process is still difficult to explain by the research team.

The team calculated that at a few million volts per meter, the water film would solidify, which is only one-thousandth of the electric field strength previously calculated by scientists using computer simulations.

Jiang Xun said that in fact, an electric field of several million volts per meter is widespread, such as the static electricity generated when taking off a woolen sweater, mobile phone batteries and even ions in biological cells can form such an electric field.

Mikel Salmeron of the Lawrence Berkeley Laboratory in California, USA, commented that if the same principle can be applied to charged biomolecules, such as proteins, then it can have an impact on those biomolecules.

The temperature of 0 degrees does not freeze.

When the temperature just drops from above zero to 0, the water will not freeze, because the latent heat released during freezing is very large, and if it is exactly freezing, the ice crystals that have just formed will melt quickly. Therefore, the general temperature is below zero before the water freezes.

Introduction to Road Icing:

Road icing tends to occur during the period from November to April of the following year (i.e. winter and early spring). In the northern part of China, especially in the northeast and northern Inner Mongolia, the road is often iced.

And in the southern region of our country, snowfall is generally "wet snow", often belongs to 0 4 mixed water, landing into ice water slurry paste, a night temperature drops, will solidify into a large piece of ice, as long as the local winter minimum temperature is lower than 0, there may be road icing, as long as the temperature does not rise enough to thaw the ice, it will always be as solid as a rock.

Generally speaking, when there is a wide range of strong cold air activities that cause the temperature to drop (meteorologically known as cold wave), if accompanied by rain and snow, the road ice phenomenon is most likely to occur.

Yes, water will still evaporate at zero degrees, and evaporation will release heat, so the actual temperature of the water will be less than zero degrees and can freeze.

If the temperature is below 0 degrees Celsius, the water will freeze, and when it is equal to 0 degrees Celsius, it is a mixture of ice and water, which is what is known in physics. It's a kind of common sense of nature.

In the narrow sense, the process of acquiring knowledge or skills through reading, listening, researching, observing, understanding, exploring, experimenting, practicing, etc., is a way of behavior that enables individuals to obtain continuous changes (improvement and sublimation of knowledge and skills, methods and processes, emotions and values). For example, the process of acquiring knowledge through schooling.

In a broad sense, it is the relatively long-lasting way of behavior or behavioral potential that occurs through the acquisition of experience in the course of human life.

There is always a very strange phenomenon in society, some people complain that the boss treats him badly, the salary is too low or something, but they ignore that they are lazy and worthless.

Since ancient times, people have said "the cycle of cause and effect", and it is true that what you plant will reap the effect. This is the consequence of not studying well, so what is the importance of learning?

Things gather people in groups, what kind of people will be in what kind of environment. I will gradually understand what kind of ability I have. Understand your own ability and make friends at the same level, the higher your personal ability, the higher the quality of your natural friends.

In most cases, the better you learn, the more you will improve. are also rich people, nouveau riche fiddling with money will only make people feel vulgar, while people who are really knowledgeable will have a very different temperament.

High-end companies and products are inseparable from knowledge, only in knowledge not to lose to others, in other places not to lose others.

Children's education should start from an early age, and what kind of parents and children will most likely become. Only by improving one's own level will one educate better children. And not a short-sighted person.

Because literate parents will bring more help to their children in terms of growth, and if children have literate parents, they will usually live a better and smoother life on the road in the future.

Learning is very important, and the quality of learning ultimately determines the quality of friends, self-cultivation and the education of future generations, so we should work hard in learning.

The temperature at which water freezes is not affected by the ambient temperature, but by the atmospheric pressure. At a standard atmospheric pressure, the temperature at which water freezes is 0 degrees Celsius, and at a standard atmospheric pressure, when the temperature is below 0, the water freezes; At any pressure, the water temperature is below freezing point and can freeze, and the volume of the water increases as it freezes.

Summary. Yes, at room temperature and pressure, ice at 0 degrees Celsius will melt in water at 0 degrees Celsius. Since the melting point of ice is 0 degrees Celsius, if you put 0 degrees Celsius ice in 0 degrees Celsius water, it will melt because the temperature does not change.

At room temperature and pressure, will ice at 0 degrees Celsius melt in water at 0 degrees Celsius.

Yes, at room temperature and pressure, a 0 degree Celsius Ice Trip will melt in 0 degrees Celsius water. Since the melting point of the ice hall mold is 0 degrees Celsius, if you put 0 degrees Celsius ice in 0 degrees Celsius water, it will melt and melt because the temperature will not change.

Okay thank you! What is average speed.

The average velocity Qi Qi cover refers to the total distance of the object moving in the same direction in a certain period of time divided by the total motion time, which is expressed by the formula v=s t, where v is the average velocity, s is the displacement of the object in a set time, and t is the total time of high motion.

A standard atmospheric pressure is not at room temperature and pressure.

Yes, at standard atmospheric pressure (also known as normal temperature and atmospheric pressure) is kilopascals (kpa), which is also equal to 1 standard atmosphere (atm), and the exact value is hpa (hectopascals) or 760 torr. Each place has its own atmospheric pressure, which may fluctuate a little, but they will all tend to touch this value, and this is the normal temperature and normal pressure under the standard large opening hole air pressure.

Take the melting ice to a room with a temperature of 0 degrees Celsius, and the ice will continue to melt because the melting point of the ice is 0 degrees Celsius.

In an atmospheric environment, the melting point of ice is 0. 0 When water freezes into ice, it increases in volume by about 1 9. It has been observed that when water freezes under closed conditions, the pressure generated by the increase in volume can reach 2500 atmospheres.

There is a wonderful relationship between the melting point of ice and its pressure: below 2200 atmospheres, the melting point of ice decreases with increasing pressure, about 1 degree Celsius for every 130 atmospheres of pressure increase.

After exceeding 2200 atmospheres, the melting point of ice increases as the pressure increases. The melting point of ice is -17 at 3530 atmospheres and 0 at 6380 atmospheres.
