Let You Drive The Excavator, You Dug Out The Nuke

521. With 3,000 Years Of Tibetan Ice History, You Will Also Be An Ancestor From Now On! (Please Orde

“The temperature drops as it cools down in the well.”

"When you pick it up from the well, the outside air will enter the bottle through the gaps in the silk fabric. w

"This is equivalent to a process of air expansion, and expansion consumes internal energy."

"Absorbing heat from the bottle causes the temperature inside the bottle to drop even further.

"Eventually the water vapor condensed and formed ice."

"From a physical point of view, it is indeed feasible to make ice from hot water.

"But there is very little ice created, most of it is just ice slag."

"Coupled with hot water ice making, the requirements for air humidity of 13 degrees, container volume, and water temperature are very high."

"There is simply nothing that scientists today can replicate perfectly."

“Due to the scarcity of ice, the ice at that time was actually provided to the royal nobles.

"Ordinary people are really not lucky enough to suffer."

“During the Tang Dynasty, the ancients mined large amounts of saltpeter when producing gunpowder.

"By chance."

"They discovered that saltpeter absorbs heat when dissolved in water."

"It can quickly cool water at room temperature and freeze."

"This convenient and fast ice making method gives ordinary people the opportunity to enjoy ice cubes in summer."

"It works by putting water in a jar."

“Get a bigger container of water.”

"Then put the jar into the container."

"As long as you add saltpeter to the container and let it melt and absorb heat, the water in the jar will freeze quickly."

"By the Ming and Qing dynasties, making ice and eating ice had become very popular among the people."

"And this method has also spread abroad."

“There were even ice sculptures of art at that time.”

[Now another question arises, can ice made from saltpeter be eaten? 】

[When you ask this question, you can clearly understand that you are a person who lacks imagination. 】

[Why do you ask such a stupid question? Food made by the isolation method is edible. Don’t you even know this? 】

[Many people nowadays feel that they are much smarter than the ancients. I think there are some issues that you don’t need to tell these people who think they are smart. 】

[When did you start advocating drinking hot water instead of eating ice?]

[Lack of substances, for disinfection. 】

[It was in modern times that such a saying suddenly came into being. 】

[It’s really amazing. The ancient Chinese people have used ice for more than 3,000 years.]

[Alas, after 2000, we will also be ancients. 】

[These royal nobles really enjoy themselves very much]

[There is so much ice in Antarctica, it would take more than ten or twenty carriages to move it]

[I want to know if the current historical records are being continued. 】

[Really very knowledgeable. There are many 200 things that I have never been exposed to before. After hearing Fang Yang's explanation, I felt a sudden enlightenment. 】

[The wisdom of the ancients is true and allows us to continue to learn and explore. 】

[No wonder there is a saying that people who cut ice do not raise cattle or sheep. 】

[I’m not surprised. At that time, the climate was lower than now. Of course there was ice. Now that the temperature is so low, there is less snow in many places, but the storage method is quite good. 】

[Although the methods of use are the same, ancient refrigerators are not refrigerators. One puts ice in the cabinet, and the other is a freezer that can make ice by itself. I think the two cannot be confused. 】.
