Chapter 442 Four degrees of water temperature

When everything fell into order, Yuzi was always extremely bored, and handed over his daughter Xianhua to his grandmother Li Jing, Chen Weizheng and Liu Yi decided to travel, this time to Antarctica. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 info//High-speed update// To pass this practice, Liu Yi broke through the Tongmai period in one fell swoop, while Chen Weizheng was much more difficult, absorbing the cold and ice qi of the polar regions, especially the extremely cold qi, Chen Weizheng believed that the water and qi of the five elements were sacred.

Antarctica is the last continent on Earth to be discovered and the only continent uninhabited by humans. The entire Antarctic continent is covered by a huge ice sheet, with a total area of 13.9 million square kilometers, equivalent to the area of China and the Indo-Pakistani subcontinent combined.

Chen Weizheng's finger move tried to find a foothold near the South Pole, which was also too difficult, with strong winds and steep mountains, and nowhere to put his feet. At least it can't stand on the surface, and even if it barely stands, there is no way to collect gas, let alone condense it. Or Liu Yi is comfortable, Chen Weizheng's finger moving is her safest harbor, as soon as she enters the finger movement, she begins to settle down, Chen Weizheng added some spirit bodies to her, and then ignored her, it seems that there is no suspense in breaking through the pulse period.

There was no way to settle on the surface, so he went directly underground, and Chen Weizheng took out a drill rod that he had previously used in the Kra Isthmus from his finger move, shot out the move, and plunged it straight into the ice. Suddenly, a small hole of about ten centimeters appeared in the ice, and I don't know how deep it is. Chen Weizheng asked the moving finger to drill into the hole, and soon arrived at the drill rod, about 30 meters deep, Chen Weizheng collected part of the surrounding ice into the moving finger, made a space of about fifteen cubic meters under the ice, and then walked out of the moving finger into this ice and snow space.

Black, the first feeling is black, there is no bright ice, there is no crystal clear as the legend, it is completely no different from in an underground cave. It's just that there's a chill here, like a needle tip.

After Chen Weizheng got used to it, he began to collect the water vapor in the ice. Suddenly, as soon as he absorbed it, Chen Weizheng didn't feel a shock all over his body, it was too cold! Truly bone-chilling. Soon his body was frozen, and before he could still move, Chen Weizheng flashed in and moved his fingers, and his whole body was still trembling violently.

Seeing Chen Weizheng's embarrassed image, the word "stupid" appeared on the whole screen, and many "stupid" words formed various patterns and changed on the screen. Chen Weizheng walked to the screen with a sneer, knowing that he was making a joke again.

The screen tells Chen Weizheng that gold, wood and earth are the existence of three solid forms, water is the existence of the liquid form, and fire represents the gaseous and ionic states, which are the basic elements that make up the world, thunder and lightning are phenomena, ice is change, not the basic elements, nor is it an extension of the five elements of the caste. It is completely wrong to say that the extension of fire is thunder and the extension of water is ice, and that wind is classified as wood and thunder as gold. Running into the ice to beg for water vapor is completely imaginary, a bit self-righteous.

Chen Weizheng smiled, his old face flushed. Knowing that he had made a mistake and was about to leave, the screen told him to collect another one or two hundred square meters of ice, and then leave, Chen Weizheng hurriedly collected another three or four hundred square meters of ice, and almost half of it was filled in his fingers.

Coming out of the small hole, the screen asked him to find a place with a relatively high temperature, Chen Weizheng chose the Sahara Desert in Africa, in the center of the desert, the screen asked Chen Weizheng to send the collected ice out to melt naturally.

With a temperature of nearly 60 degrees, the ice melted quickly, and in less than three hours, except for seeing that the ground was still a little wet, there were no ice cubes. At this time, a small crystal slightly larger than a peanut and pale white suddenly appeared in his fingers, Chen Weizheng picked it up and looked at it, a bit like a fossil, and a little like jade, the temperature is not very low, about ten degrees Celsius, put it in his hand, it is cool and cool, and it is very comfortable. The screen asked Chen Weizheng to walk around the place where the ice melted, as if he was picking up dzi in the canyon of the Brahmaputra River.

Chen Weizheng walked out of the finger and realized that this job was not easy and quite sinful. Because the temperature outside is so high, I can't even breathe, let alone walk on it. The thawed ice water was under the sun's rays, turning into moisture and rising, and Chen Weizheng was wet after walking a few steps, unable to tell whether it was moisture or sweat.

No way, if it's easy to go, if it's not good, if it's not good, I got an umbrella in my fingers, although it doesn't have much effect, how much can I top. After walking for a whole hour, he walked through the melting area, and as soon as he finished walking, Chen Weizheng flashed into the finger moving and sat on the ground of the finger moving, panting, sweating profusely, and almost sticking out his tongue like a Laipi dog.

Before he could take a breath, his eyes were attracted by the small desktop under the screen, and he crawled to the screen while rolling the belt, and on the small desktop was the kind of small pale white crystals he saw before, a large number, nearly a hundred grains.

Holding one, looking at the screen, he asked, "What is this?" ”

"This is the Ice Soul Crystal." The screen knew that this thing was too mysterious for Chen Weizheng, and the content displayed was a little more: "In layman's terms, it is a fossil of ice, and there are many under the Antarctic continent, but this thing takes a long time to generate, millions of years to form." ”

"Will it melt at room temperature?"

"No, although it's ice, it's already a fossil, this thing doesn't have much effect, it can be made into beads and can be used as a bracelet or necklace, and it can be worn on the body, it can bring you coolness all the time, and it can remove the anxiety in your heart when you practice, and it is a tool that a cultivator should have."

Chen Weizheng snorted, and told the screen that he knew, in fact, what he wanted to know most in his heart was where he could get the water vapor of the Five Elements Water.

The screen was clear about his thoughts, saying, "Water is densest at 4C. As long as you have water at 4C, the efficiency of gas recovery will be ten times higher than that of ordinary water. ”

"Why is water densest at 4C?" Chen Weizheng became a curious baby at this moment.

The general objects are: the higher the temperature, the lower the density; The temperature decreases and the density increases. However, the density of water is as follows: when the temperature is higher than 4C, the density decreases as the temperature increases; When the temperature is lower than 4C, the density increases with the increase of temperature. At 4C, the density of water is at its highest.

The highest density of water at 4C is determined by the special structure of hydrogen bond association between water molecules. According to recent X-ray studies, it has been proved that ice has a tetrahedral crystal structure. This tetrahedron is formed by hydrogen bonding, which is an open relaxation structure, because five water molecules cannot take up all the volume of the tetrahedron, and hydrogen bonds in ice link these tetrahedra together to form a whole. This directional and orderly arrangement formed by hydrogen bonding has a small space utilization rate, accounting for about 34%, and therefore the density of the ice is small.

When water dissolves, a large number of hydrogen bonds are disassembled, so that the whole is divided into tetrahedral groups and scattered smaller "water molecule groups" (i.e., some association molecules formed by the association of hydrogen bonds), liquid water is no longer completely ordered like ice, but has a certain degree of disordered arrangement, that is, the distance between water molecules is not fixed as in ice, and H2O molecules can enter another microcrystalline from one tetrahedral. In this way, the intermolecular voids are reduced, and the density increases.

When the temperature increases, the tetrahedral group of water molecules is continuously destroyed, and the disordered arrangement of the molecules increases, resulting in an increase in density. But at the same time, the thermal motion between molecules also increases the distance between molecules, which reduces the density. These two contradictory factors reach equilibrium at 4C, and thus, the density of water is greatest at 4C. After 4C, the thermal motion of the molecules increases the distance between the molecules, and the density of water begins to decrease again.

It's okay that Chen Weizheng didn't watch it, but he was completely stunned after watching it.

However, he learned a truth, at 4C, water is the densest. As long as there is a large amount of 4C water, you will get twice the result with half the effort. As for how to get 4C water, go to the Oriental Development Zone and let the technicians get a constant temperature refrigerator.

"You'd better add the right amount of pebble powder to the water, it will make your gas extraction more effective." On-screen display.

"What's the ratio?"

"Less first, then more." The screen said: "First of all, the kind of 12V you configure, at most no more than 60V, how much it is, depends on your physical condition." ”

Coming out of the fingers, Chen Weizheng came to Funan Oriental Development Zone, accompanied by Governor Chen Qiancheng, and walked into the laboratory of Zhongnan Refrigeration Equipment Company, which was relocated from Toshiba Refrigeration. When the name was changed, some angry young people thought that Zhongnan refrigeration, which sounded like China refrigeration, had a historical shadow and could not be used. Or Chen Wei's political power is overwhelming, thinking that it can be used completely, Zhongnan is Zhongnan, and the branch is Zhina, and there is no need to be far-fetched. Even if it is directly called Zhina Refrigeration, there is no problem, as a historical title, it cannot be evaded or even erased a historical memory. A country and a nation must mature, there is no need to be so naïve forever, so fragile, and the ability to bear is like a gauze as thin as a cicada's wings, which will be broken when it is stabbed, and scream when it is broken, like an uneducated rural woman, whoever takes her a piece of firewood, can also scold from the street to the street.

Zhongnan Refrigeration Equipment Company took this matter as a political task to complete, and experts from Toshiba's headquarters also flew to the Dongfang Industrial Zone to offer advice, and in less than half a month, samples appeared. Chen Weizheng is very grateful to them, allocated a special fund, was rejected by Zhongnan Refrigeration Equipment Company, Chairman Du Bianxiong said, as a new Ming people, thank you very much for the King's acceptance, Zhongnan Refrigeration Equipment Company is an enterprise that understands Entu, and hopes that the King can give a chance for the company to repay. This is the heart of the enterprise, the gratitude to the king, not a political task, not a horse, it is the duty of a man. From a business point of view, the king can give such a task, which is the trust of the enterprise, the recognition of the enterprise, and the promotion of the enterprise. If this matter is used to hype, the advertising benefits far exceed the cost of developing equipment, to put it mildly, if you want the royal family's money, the products of Zhongnan Refrigeration Equipment Company will definitely not sell well in the new Ming Kingdom. I hope that the king will be fulfilled.

Chen Weizheng had no choice but to give up, telling them that they could use this matter to hype, and the image of the king was insignificant in front of the interests of the enterprise.

Although I don't know what Chen Weizheng used to create this thing, the refrigerator powered by 240V direct current was sent to the palace of Longshan City in the form of a work of art.

In the moving fingers, Chen Weizheng added liquid, and when the electricity was turned on, two tons of water dropped to 4C in an hour, and in the watertight cabin, Chen Weizheng entered the state of gas extraction, and in 24 hours, two tons of water only left about 300 kilograms of impurities, and other water disappeared without a trace.
