Turn water into ice
Li Zhen was also stunned, filled with surprise. Did he discover ammonium nitrate? But when I looked at the table, there was obviously no such thing as ammonium nitrate, or even calcium nitrate.
Just a bunch of white crystals.
Li Zhen has not been verified and does not know what the white crystal is. I was a little shocked. Could it be that Qi Denming had really discovered a mysterious phenomenon? Is it something you don’t know
"Senior Qi, please give me a demonstration."
Li Zhen said impatiently.
Qi Dengming saw Li Zhen's gesture of asking him for advice, and his heart was filled with excitement. He laughed and said, "Brother Li, don't worry, let's make an agreement first. If you lose, you will have to become my teacher. Do you agree?"
"I promise."
"Okay, so many people witnessed..."
"Are you done yet?"
"Can we start quickly?"
"I'm so anxious, can't you hurry up?"
“…”
The students around him couldn't help but started to show off, and they interrupted him one after another.
Qi Dengming smiled awkwardly and said, "Okay, Brother Li, you have to keep an eye on it. But it doesn't matter if you don't know. This is what I discovered accidentally through trial and error. There is no limit to learning and hard work, and you still have a long way to go in the future. ,Do not be discouraged."
Li Zhen nodded: "Yes, the school motto of Fuxing University is modesty, prudence, and seeking truth from facts. Senior Qi's lesson is right. Can we start now?"
Qi Denming's face straightened: "Look, this is a glass of water."
Qi Denming pointed to a glass of transparent water on the table.
'Hulala' Everyone gathered around, and the people outside crazily squeezed in, stepping on their feet to look inside.
Li Zhen also stared at the glass of water with wide eyes, wondering what Qi Dengming was about.
But he saw Qi Denming's enigmatic smile and stretched out a finger: "Look, everyone is watching. This is a finger. I have magic. I can make this cup with just this one finger." Do you believe that water freezes?"
"I can catch you."
"Are you dreaming? Is there still magic?"
"If you can freeze this glass of water with your fingers, I'll eat the glass."
“…”
But Li Zhen was stunned, did he just need one finger? There was a smile in his eyes, and he probably guessed what this was. Well, I thought someone would give me a surprise...
Qi Dengming blushed and shouted: "You don't believe it, do you? Watch. Don't blink. Look over here. Watch carefully."
Even Qi Lengzi and Xu Shenxue were aroused by their curiosity. They crowded together with the students and pierced their necks to take a look.
However, Qi Denming's index finger gradually reached towards the beaker, and then gently moved towards the water surface.
A strange phenomenon occurred.
As his fingers left, the entire surface of the water immediately began to solidify, forming crystals. Then the crystals spread rapidly downward.
In just a few seconds, while everyone at the scene was stunned, the glass of clear water completely solidified and turned into ice.
"ah!"
"What the hell!"
"He really knows magic!"
"This is impossible, this is not scientific at all. There is nothing on his fingers. I just saw him using that finger to grab a steamed bun and eat it, and there was nothing on his fingers."
"He can literally turn water into ice."
"Damn it, Senior Qi, you are so handsome. How did you do this? This is impossible!"
"What the hell, what kind of phenomenon is this? It's just autumn, and the weather hasn't turned cold yet. How can the water freeze in the summer?"
“…”
With a 'buzz', the entire teaching building exploded.
The commotion in the Chemistry Building caused a sensation in the whole school. Students from other departments in the school ran to the Chemistry Building like crazy and squeezed in as hard as they could.
"I heard that Senior Qi actually turned water into ice!"
"He did it with just one finger."
"This is simply impossible. I don't believe it. The weather is still autumn. How could he..."
"He knows magic."
"Quick, classmate, make way for me to go in and take a look!"
"Don't crowd, don't crowd."
“…”
Xu Shenxue took a breath: "Classmate Qi, what's going on!"
Qi Dengming smiled but said nothing, looking at Li Zhen enigmatically: "Become your disciple to me."
Li Zhen smiled bitterly: "Can I touch this ice?"
"Can."
Li Zhen reached out and touched it, and gave another helpless smile, and said faintly: "Senior Qi, I admire you for discovering this amazing phenomenon. But... maybe it will be better for you to research the third icing method next time. By the way, next time it will be better to research how to actually turn water into ice. I am talking about real ice, not this fake ice."
"Fake ice?"
Qi Denming said angrily: "Everyone has witnessed the process of water freezing with our own eyes. Why do you say this is fake ice?"
But Xu Shenxue's eyes lit up and he kept mumbling: "The third kind? The third kind? Does it mean Li Zhen knows two ways of icing?"
Li Zhen sighed: "In chemistry, this is a phenomenon of hot ice. The so-called hot ice is the phenomenon of water solidifying when the temperature is higher than 0 degrees, level with room temperature, or higher than room temperature. This is called hot ice. And In fact, the freezing point of water is below 0 degrees, and it freezes with the difference in atmospheric pressure. So this hot ice is strictly false ice."
"Hot ice!"
Someone exclaimed and reached out to touch the ice in the beaker, but felt a burning sensation on the tip of his finger.
Screaming like a ghost: "Hey, this ice is really hot."
"Ah, it really is."
"It's hot ice."
"The temperature must be 40 or 50 degrees, right? How can water freeze at 40 or 50 degrees? This is amazing."
"It's really hot."
“…”
Qi Denming's face turned a little red: "Yes, it's hot ice. But it's still ice."
"This is not ice."
"Don't talk nonsense. Everyone has seen that this is water that has solidified. Why are you telling lies with your eyes open? What is an object that has solidified water other than ice?"
Li Zhen said: "You are not water either."
"You fart! Why isn't this water?"
Qi Denming was a little crazy.
The classmates also said: "Junior Li, we have all seen it. It is transparent and clear. Is it really water?"
Li Zhen shook his head: "You can only say that this is called a 'liquid', but you can't say that it is H2O water."
Zyden Minggeng scratched his neck: "Then what do you think this is?"
"Supersaturated solution of sodium acetate."
As soon as he said this, Qi Denming choked on his saliva and looked at Li Zhen in shock: "You... you, how did you know? This is a new phenomenon that I accidentally discovered while doing experiments. How did you know?"
Li Zhen said with a smile: "Those white crystals on the table must be sodium acetate crystals. I wasn't sure what they were at first, but when I saw the hot ice phenomenon, I knew they must be sodium acetate crystals."
"right!"
Qi Denming nodded. Those white powder crystals on the table are indeed sodium acetate crystals. He smiled bitterly in his heart, originally planning to explain and demonstrate it to everyone when everyone else couldn't understand it. Unexpectedly, Li Zhen saw through it at a glance.
"In fact, in addition to the sodium acetate supersaturated solution, your fingernails should also be stained with a few sodium acetate trihydrate crystals."
Qi Denming looked at Li Zhen in horror: "How do you know!"
You know, in order to cover up that there was nothing on his finger, Qi Denming just turned water into ice out of thin air to increase the sense of mystery. I deliberately used this hand to eat steamed buns before. But I didn't expect that Li Zhen even knew this!
