Blind for five years: Has Cao Wei unified the Three Kingdoms?

"Do you know why dishes are sweeter after snowing in winter?"

Ye Qing's small courtyard!

At this time, Ye Qing was teaching Cao Ang and the three!

And the spectators were not only Dian Wei, but also Cao Hong and Sable Cicada!

"Is it possible that sir is because snowflakes contain sugar?" Cao Anmin replied.

Hearing this answer, Ye Qing almost didn't turn his back.

"So Cao Er, have you licked snow in winter?"

Cao Anmin replied very seriously: "I licked it when I was a child!" "

This guy really licked it, and Ye Qing asked angrily, "Is the snow sweet?" "

Cao Anmin shook his head with red eyes: "It's not sweet, it's just a little cold, it's cool to the heart!" "

"I almost froze my tongue!"

Not cool or snowy?

Ye Qing gently wiped the blackboard with the blackboard and said, "The vegetables after the snow are sweet, that is because plants need to protect themselves from the cold, so sugar is produced through a series of chemical reactions in the body." "

"When we humans eat it, we naturally feel much sweeter than before it snowed!"

So it is!

The three immediately took notes.

Then Ye Qing said, "Do you know why it's not cold when it snows, and cold when it melts snow?" "

Cao Ang and the others still shook their heads, and Cao Hong and the others were also confused.

Who can answer this question, and why?

Ye Qing explained: "Because water vapor condenses into snow and needs to release heat, it is not cold when it snows.

And melted snow absorbs heat when it changes from snow or ice to water, so dissolved snow is cold! "

That's the reason.

Xu Huang and Sable Cicada were both surprised.

Such a mysterious thing, Mr. Ye understands.

Could it be that he is really a heavenly immortal!

"Last question for today?" Ye Qing pondered for a moment before asking, "The ordinary flames we see are generally divided into three layers. "

"The innermost layer is a dark blue flame, the middle layer is a dark red or light yellow flame, and the outer layer: nearly colorless."

"Do you know which layer has the highest flame temperature? And what is the reason for its high quality? "

At this time, Cao Xiu directly replied: "Sir, I know!" "

"Of course, the innermost inner flame has the highest temperature, because he is close, and the fire light comes from there!"

The corners of Ye Qing's mouth rose slightly: "What do you think?" "

Cao Ang and Cao Anmin hesitated and said, "The innermost layer!" "

Ye Qing then asked Dian Wei and Cao Hong and the others: "What do you think?" "

Dian Wei and Cao Hongdu said, "The innermost layer!" "

Discerning people know that the innermost flame is the highest.

Isn't this common sense?

Ye Qing smiled and shook his head slightly: "Wrong, the innermost temperature you think is the lowest." "

"The invisible flame in the outermost layer is the hottest!"

What the?

The outermost flame has the highest temperature.

This simply subverts common sense.

"If you don't believe it, you can wipe it down!" Ye Qing signaled that everyone could do a small experiment.

When it came to doing the test, Cao Ang, Cao Anmin, and Cao Xiu expressed their calmness and urged Cao Hong to verify the authenticity.

Cao Hong is an elder, so it is naturally difficult to shirk.

So he stretched out his index finger and put it in the inner flame first, and found that the temperature did not seem to be very high.

After taking it out and slowly placing it on the outer layer without flame color, it suddenly felt burning.

Frightened, he immediately withdrew his hand.

Cao Ang, Cao Anmin, and Cao Xiu laughed.

Because they knew that Mr. Ye's words must be true, and he said that the external flame was high, which must make sense.

So they all suppressed their curious hearts and did not test them personally.

Only then did Cao Hong realize that he had fallen for three unlucky children.

So he slashed at the three of them.

The mink cicada is laughing and trembling

It was also the first time she had heard such magical knowledge, and he was still a girl, naturally with the innocence of a girl.

Ye Qing couldn't help but laugh when he heard that Cao Hong wiped it with his index finger, and then he took a small wooden strip and trembled to bring the wooden bar close to the flames, and the mink saw that Ye Qing had not succeeded several times.

So he stepped forward and said, "Sir, I'll help you!" "

The mink cicada held Ye Qing's hand and controlled the wooden bar to put it in the outer flame position first, and the wooden bar quickly burned and turned black, and then burned.

"Little cicada girl, you pick up a stick of similar size and put it in the inner flame, so that everyone can see the specific changes!" Ye Qing ordered.

The mink cicada replied and let go of Ye Qing's hand.

Ye Qing took a step back and withdrew the hand that had been shaken by the mink cicada into his sleeve.

The nasal cavity is also surrounded by the faint body fragrance of mink cicadas.

With the help of mink cicadas, everyone can observe more intuitively and three-dimensionally.

Deeply understand the principle of low internal flame temperature and high external flame temperature.

And Cao Honggang felt that his intelligence was pressed to the ground and rubbed fiercely.

My burnt hand?

Why am I so stupid and why experiment with my hands?

"Sir, I'll go first, Boss Cao is still looking for me there!" Cao Hong fled the same way, he was afraid that if he stayed, he would be even more embarrassed, and he would lose face in front of the juniors!

Ye Qing naturally would not leave Cao Hong behind.

Then he continued to teach Cao Ang, Cao Anmin, and Cao Xiu for a while, and then the class ended.

"Ding! This time, the host taught students several physics trivia, and obtained a dressing mirror (circle) side, a magnifying glass, a pair of sunglasses, and a pair of telescopes!

Forehead!

There are a lot of things, all mirrors!

Ye Qing smiled bitterly.

I can't see with my own eyes, what do I want these mirrors for!

"But sunglasses can be worn so that students won't be scared by my blind eyes when they go to class!"

As soon as he thought of this, Ye Qing immediately took out his sunglasses and put them on for himself.

The mink cicada and Dian Wei on the side suddenly widened their eyes and were dumbfounded!
