What kind of process is liquification?
Liquefaction referred to the process of a substance changing from a gaseous state to a liquid state. This process would release heat to the outside world. There were two main methods to achieve liquification. One was to lower the temperature (this method was suitable for all gases at all temperatures), and the other was to compress the volume (some gases were suitable at a certain temperature, usually at room temperature. Special gases had to be cooled down first before compressing the volume). Any gas can be liquefied when the temperature is low enough. At a certain temperature, compressing the volume of the gas can also make some gases liquefied, or both methods can be used. However, when compressing the volume, if the temperature of the gas was higher than its critical temperature, it could not be compressed and liquefied. For example, the critical point of hydrogen and natural gas was relatively high, and they could be liquefied at room temperature. The critical point of hydrogen and nitrogen was very low, and they had to be deeply cooled to be liquefied at the same time. The novel "Watching the Moon on Fish Island" is equally exciting.

For gases with high critical points (such as hydrogen and natural gas), they could be liquefied by pressurizing them at room temperature. For gases with low critical points (such as hydrogen and nitrogen), they must be deeply cooled while pressurizing them to achieve crystallization.

What is an example of liquification and heat release?
The following is an example of the heat release from the liquification: 1. Being scalded by water vapor at 100 ° C was often much more serious than being scalded by boiling water at 100 ° C. This was because water vapor released a lot of heat when it liquefied. 2. In the winter, when one breathed on their hands, the water vapor that came out of their mouth liquefied and released heat, thus warming their hands. 3. When boiling water with a kettle, the white gas on the mouth of the kettle was the small water droplets liquefied by water vapor. This process released heat.

What is the principle of liquification and heat release?
Based on context alone The process of changing a substance from a gaseous state to a liquid state was called liquification. The principle of heat dissipation was mainly based on the interaction between molecules. In the gaseous state, the distance between the molecules was very large. The molecules had high kinetic energy and could move freely. The interaction force between the molecules was relatively weak. When gaseous substances began to liquify, the distance between molecules gradually decreased, and the attractive force between molecules began to play a greater role. In order for the molecules to get close and form a liquid structure, the molecules need to release energy, and this energy is emitted in the form of heat. In other words, the kinetic energy of gaseous molecules would decrease during the process of crystallization, and the energy would be converted into heat energy and released, thus showing the phenomenon of crystallization and heat release.

An example of liquification
The following is an example of liquification: - In the industrial aspect, gases such as hydrogen and natural gas had a high critical point. Pressurizing them at room temperature could transform them from a gaseous state to a liquid state. This process was called crystallization. The liquefied gas was easy to store and transport. - For example, China's October liquefied gas production reached 4.57 million tons, an increase of 2.5% year-on-year. Its production process involved the liquefied gas. - Liquefaction was a feature in the graphics processing software, Photoshopped (PS). For example, in the Photoshopped Liquefaction Retouching tutorial, the Liquefaction feature was used to adjust the body proportion of a person's image, draw the jaw line, and other operations. However, the concept of Liquefaction here was a kind of transformation operation on the image's pixels. It was different from the liquification of the material state change, but it also borrowed the concept of Liquefaction to describe the flow and transformation effect of the image's pixels.1 The novel "Watching the Moon on Fish Island" is equally exciting.

10 examples of liquification
1. The "white gas" exhaled by people in winter, the "white gas" around the ice cream, the "white gas" emitted from the mouth of the kettle, and the "white gas" when the refrigerator opened. 2. Iced beverage bottles sweat, water pipes sweat in summer, and glass in winter. 3. In the winter, he went from outdoors to indoors, and the "fog" on his glasses. 4. He opened the lid of the pot and couldn't see clearly with his glasses. There was a layer of fog. 5. The formation of fog, dew, rain, and clouds. 6. A layer of mist gathered on the bathroom wall after taking a shower in winter. 7. When the weather was cold, water droplets appeared on the inner surface of the window glass in a warm room. 8. In the summer, the glassware that was taken out of the refrigerator's preservation room had small water droplets on the surface. 9. When eating popsicles in summer, one could see "white gas" near the popsicles. 10. The dewdrops forming on an autumn morning. The novel " Watching the Moon on Fish Island " is equally exciting.

An example of liquification
Liquefaction refers to the process of turning a gas into a liquid state. The following are some examples: 1. A layer of mist gathered on the bathroom wall after taking a shower in winter. This was because the steam emitted by the hot water met the colder wall and liquefied into small water droplets. 2. In winter, when a person spoke, a mass of "white gas" would be exhaled from his mouth. The hot air exhaled would be liquefied into water when it met the cold environment. In summer, when the wrapping paper on the popsicle was peeled off, the popsicle would emit "white gas", which was formed by the condensation of water vapor in the air. 3. When the weather was cold, water droplets appeared on the surface of the windows in the warm house. 4. Xia Tian took out the originally dry glassware from the refrigerator's preservation room. After a while, there were small droplets on the surface. 5. When eating popsicles in summer, one could see "white gas" near the popsicles. 6. When people wearing glasses ate, there would be a "white fog" on the glasses that blocked their vision. 7. When boiling water, the "white gas" that appeared around the top of the container lid. 8. When the weather returned, small droplets of water would appear on the glass of the classroom window. 9. When the doctor examined the oral cavity, he had to heat the small mirror in the mouth to prevent the water vapor in the mouth from liquidating and blurring the mirror. 10. Autumn fog, the formation of morning dew. 11. In winter, it was easy for the glass in the car to be foggy, and when people wearing glasses entered the warm room in winter, the lenses would be foggy. 12. When boiling water with a kettle, the white gas on the mouth of the kettle was the small drops of water liquefied by steam. The novel " Watching the Moon on Fish Island " is equally exciting.

The concept of starch liquification
Liquefaction of starch referred to the transformation of starch from a high molecular state (starch granules) to a lower molecular state (starch) under the effect of alfa-starch. At the same time, the starch's stickiness decreased, which was a process from semi-solid to solution. In the process of producing starch sugar by the starch fermentation reaction, the crystallization was an important step, which laid the foundation for the subsequent steps such as glyphs. For example, in the process of producing mannitol using starch as raw material, the crystallization of starch was achieved through a series of operations such as spraying crystallization, maintaining the reaction by lowering the temperature, replenishing the crystallization of the starch, and creating an environment suitable for the crystallization of the starch, such as adjusting the pH.
