Technique of Liquefaction
There were two ways to liquify a gas. One was to lower the temperature, and the other was to compress the volume. However, different gases had different conditions. For example, the critical point of hydrogen and natural gas was higher, and they could become liquid under normal 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. If it was in the image processing software Photoshopped (PS), the liquification operation technique was as follows: 1. Body proportion adjustment: - He could first combine Free Transformation and Liquid to adjust the overall body proportions. He had the habit of liquifying the whole body first before the parts. He had to first solve the problem of his body size and the ratio of his head to his body. For example, when adjusting the thickness of the back, first select the layer, then use the button to copy the layer to protect the original image. Then use the rectangular marquee tool box to select the area that needs to be adjusted (such as the entire right side of the arm). Through the free transformation under the edit menu bar (shortcut key: Control + t), press and hold shift without letting go, and place the mouse pointer on the center of the right side to zoom. - If there were problems with the head being deformed or the connection being exposed, he could use a layer mask to hide the unwanted adjustment effect. After selecting the adjusted layer, click the third icon under the Layers panel to add a layer mask. Change the color of the mask to black to make the adjustment effect disappear. Use the brush tool (the size of the pointer can be adjusted by the left and right parenthesis on the right side of the p key. The brush's Opacity and Flow are set to 100%) to apply the mask with black paint to erase the blocked parts. 2. Head to body ratio adjustment: - After selecting the topmost layer that could be marked (press the shortcut key, Ctrl-alt-shift, and +e), use the Elliptical Marquee Tool to draw a marquee that covers the head. Then use the Distortion-Spherification menu command under the filter menu bar to shrink the head (the value usually does not exceed 10, if it is set to-9). If you need to shrink it further, you can repeat the steps. 3. Local Liquefaction: - From the filter menu bar, he found the Liquefaction menu command. On the left was the adjustment tool, and on the right was the adjustment attribute. The pressure value was usually set to 50. - Commonly used tools were the Forward Shaping Tool (for example, when adjusting the flesh on the chin and neck, you can adjust the size of the brush pointer and push the flesh in the desired direction), the Freeze Mask Tool (the shortcut key is F. When adjusting the head shape without affecting the position of the five senses, you can use this tool to freeze the five senses. The red area represents the frozen area, and the subsequent operations will not affect the area), etc. The novel "Watching the Moon on Fish Island" is equally exciting.

What is Liquefaction?
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 ways to achieve liquification. One was to lower the temperature, and the other was to compress the volume. The critical temperature was the highest temperature at which a gas could be liquefied. Gases such as nitrogen and natural gas had a high critical point and could be turned into liquid at room temperature, while gases such as hydrogen and nitrogen had a low critical point and had to be deeply cooled to be liquefied at the same time.

Liquefaction characteristics
Liquefaction referred to the process of a substance changing from a gaseous state to a liquid state, which would release heat to the outside world. In this process, the molecular distance of the substance decreased, and the interaction force between the molecules increased, thus reducing the volume of the substance and increasing its density. There were two ways to achieve liquification. One was to lower the temperature, and the other was to compress the volume. The critical temperature was the highest temperature at which a gas could be liquefied. For gases with higher critical points, such as hydrogen and natural gas, they could be liquefied at room temperature by pressurizing them. For gases with low critical points such as hydrogen and nitrogen, they had to be deeply cooled to be liquefied at the same time. The novel " Watching the Moon on Fish Island " is equally exciting.

There were two ways to achieve liquification. One was to lower the temperature, and the other was to compress the volume. The critical temperature was the highest temperature at which a gas could be liquefied. However, there was also an explanation for the transformation of a substance from a solid state to a liquid state, which was called crystallization. In this process, it was achieved by increasing the temperature, reducing the pressure, or both. During the liquification process, the molecular distance of the substance decreased, and the interaction force between the molecules increased, thus reducing the volume of the substance and increasing its density, making it easier to store, transport, and use. For example, common gases such as hydrogen and natural gas could be liquefied at room temperature due to their high critical points, while gases such as hydrogen and nitrogen had very low critical points and had to be deeply cooled to be liquefied at the same time. In addition, the process of semen solidifying outside the body and then turning into liquid state is also called crystallization. Under normal circumstances, male semen is in a liquefied state when it is ejected outside the body. It will solidify into a jelly state in a very short time, and then gradually liquidize into liquid state after 10 - 30 minutes. There is also the raw material coal bed gas that has been compressed, pre-treated, and turned into liquid coal bed gas (liquefied coal bed gas) after low-temperature heat exchange.

Liquefaction applications
Liquefaction has the following applications: 1. ** Energy Sector ** - In terms of hydrogen energy, although there were many difficulties, hydrogen sublimation could help solve the problem of hydrogen storage and transportation. However, the energy consumption of hydrogen production and liquefied hydrogen was relatively high. One kilogram of hydrogen required about 50 kWh of electricity to produce hydrogen, and another 11 - 15 kWh of electricity was needed to liquify hydrogen. - In terms of traditional energy sources, there was a major breakthrough in coal direct sublimation technology. The application of this technology would help improve China's energy efficiency and promote the development of the energy field. - Liquefied oil gas is convenient for storage and transportation, and is convenient for civil and industrial use. 2. ** Medical field (not explicitly mentioned in the information provided, but supplemented from the perspective of general knowledge)** - Liquid nitrogen was used to liquify. The temperature of liquid nitrogen was extremely low, and it could be used for cryotherapies, such as removing warts, moles, and other pathological tissues on the skin. The low temperature could be used to cause the necrotic tissue to fall off. 3. ** Image editing field ** - In the PS software, the Liquefaction tool could be used to modify the image, such as adjusting the body proportion, drawing the jaw line, processing the facial light and shadow, etc. The image could be edited through various functions in the Liquefaction tool, such as the forward transformation tool, the freeze mask tool, etc., so that the image could achieve the ideal visual effect. 4. ** Physics teaching (based on junior high school physics knowledge points)** - Phenomena such as morning dew (water vapor in the air condenses when it freezes) and fog in the mountains (water vapor condenses to form small water droplets suspended in the air) could help students understand the concept of crystallization, the methods of crystallization (lowering temperature, compressing volume), and the heat release of crystallization.

The Essence of Liquefaction
Different substances liquefied for different reasons: - The essential reason for sand soil to liquify was that under the vibration of saturated silt and sand soil, the pore water pressure increased and the effective stress decreased. When the contact pressure between sand particles was equal to or close to zero, the friction resistance was also equal to or close to zero, thus showing the change from solid to liquid. - Fat Liquefaction could be caused by infection, poor suturing technique, inadequate incision protection, and other factors, which led to the appearance of fat Liquefaction in the postoperative wound. - Whether semen could be liquefied or not was mainly related to the substances secreted by the vesicle and the bladder. The secretion of the bladder directly affected the semen's liquefied state. The secretion of the vesicle, bladder, and local urethras would affect the secretion of the secretion of The novel " Watching the Moon on Fish Island " is equally exciting.

Liquefaction and vaporizing
Liquefaction referred to the process of a substance changing from a gaseous state to a liquid state, which would release heat to the outside world. There were two ways to achieve liquification. One was to lower the temperature. As long as the scientific conditions allowed, any gas could be liquefied when the temperature was low enough. The other was to compress the volume. Some gases could be liquefied by compressing the volume at room temperature. Boilification referred to the phase change process of a substance from a liquid to a gas. This process required the absorption of heat. There were two forms of vaporizing: evaporating and boiling. Evaporizing was a phenomenon of vaporizing on the surface of a liquid. It was a slow vaporizing method that could be carried out at any temperature. The temperature would drop during the evaporating process, and it had the effect of heat absorption and cooling. Its speed was related to the temperature of the liquid, the surface area of the liquid, the speed of air flow above the surface of the liquid, the humidity of the air, and the type of liquid. Boiling was a phenomenon of intense vaporizing that occurred in the body and surface of the liquid when the saturated vapor pressure was equal to the external pressure. When the liquid was boiling, it absorbed heat but the temperature remained unchanged. The boiling point of different liquids was generally different. The boiling point of the liquid was also related to the air pressure on the surface of the liquid. The boiling point increased when the pressure increased, and the boiling point decreased when the pressure decreased. Liquefaction and vaporizing were inverse processes.
