Great Tang’s Unparalleled National Teacher

"Report to the dean that they are in the laboratory."

The student said respectfully.

Zhang Feng thanked him for looking towards the laboratory. The laboratory is a place for everyone to do experiments. Usually Ma Zhou and Hao Chujun will be here.

As soon as I walked in, I saw two people lying on the table, holding Glazed Glass bottles, not knowing what they were doing.

"Ma Zhou, Hao Chujun, what are you doing?"

Zhang Feng asked suspiciously.

The two suddenly turned their heads and looked at Zhang Feng with surprise: "Benevolence, why are you here?"

After speaking, the two quickly put down Glazed in their hands. Glass bottle, walked to Zhang Feng.

"I have something to explain to you."

Zhang Feng looked towards the two, faintly smiled: "I need you to research out the facilities for heat conduction power."

p>

The two were frowned and looked at each other, a little puzzled.

"En Gong, what do you mean by this? Can you explain it?"

Ma Zhou scratched his head, a little confused.

Zhang Feng glanced at the two of them, and patiently explained: "In simple terms, it is the flow of high-temperature gas or gas composition changes and the interaction of the gas and the object. When a thing meets a strong air current, it will happen. What kind of changes, such as paper kites, why they can fly in the sky, are all affected by the air currents. I now need you to make a device that conducts heat to the other side."

"This... …"

Ma Zhou and Hao Chujun were even more confused.

Zhang Feng did not blame the two, but continued: "In fact, this is not difficult. Go and prepare the oil lamp, tweezers, iron wire, and paper. I will do an experiment for you to see."

When the two heard that there was an experiment to watch, they immediately ran away eagerly.

After a while, the two took the oil lamp, tweezers, iron wire, and paper over and put them on the table.

Zhang Feng will take out the fire fold to light the oil lamp, then draw a cigarette from his waist, dangle it on the oil lamp, take a sigh, and spit out the smoke, looking towards the two of them: "Look carefully "Hey."

"Cough cough...Okay, gracious."

Ma Zhou said with difficulty, covering his mouth and nose. Obviously, the smell of this cigarette choked him.

Hao Chujun didn't get there, he didn't tighten his mouth and nose, he kept nodded.

Zhang Feng smiled and shook his head, holding the cigarette in his mouth, picking up the paper and iron wire with both hands, and passing the iron wire through the paper, leaving a gap of two centimeters in between.

After finishing all this, he clamped one end of the wire with tweezers, and put the other end on the oil lamp to heat it.

In a short while, the wire turned black, and then slowly turned red until it turned red.

"It's red, benefactor, it's red."

Ma Zhou cry out in surprise with excitement.

For people like him who are paranoid about academics, the only thing interested is this thing.

"I know it's red."

Zhang Feng grinned, with a cigarette butt in his mouth, and spoke a little unclearly.

After finishing speaking, he took the wire from the oil lamp and looked at Ma Zhou solemnly: "You touch the two ends of the wire, what is the difference."

"Touch it?"

Ma Zhou is a little confused.

Although he is naive, he is not stupid.

This damn thing can't be burned to death by touching it?

He shook his head and refused.

Seeing this, Zhang Feng showed a smile of harmless to humans and animals: "Observe, I am doing this for your own good. You can only experience the results of the experiment by touching it, and you can remember it forever after the experience. Besides, this iron wire is not very hot, you see, didn’t I hold it too?"

Ma Zhou glanced at Zhang Feng suspiciously, fighting a huge struggle in his heart. In the end, he still Stretched out his hand.

"His..."

A sudden pain came, and he drew his hand back abruptly.

Looking back, a black mark was printed on his hand.

Ma Zhou glanced at Zhang Feng contemptuously.

Is it hot?

They are all deceptive.

I believe in your evil.

Zhang Feng didn't know his careful thoughts, but passed the wire to Hao Chujun.

"Would you like to touch it?"

Hao Chujun waved his hand quickly and took two steps back: "I'll forget it, Ma Zhou just remember the results of the experiment."

Nodded of Zhang Feng faint smile, looked towards Ma Zhou: "Ma Zhou, in fact, I am helping you. Look, you can think of this experiment when you see the scar on your hand in the future, Now, how do you feel about this experiment?"

Help me?

Ma Zhou rolled the eyes.

However, after another thought, there seems to be nothing wrong.

It is also a good thing to remember this experiment forever.

He touched his hot hand and endured the pain, said in deadly earnest: "Benevolence, there is nothing to feel. I'm a little strange, why don't you feel hot, and I will Feeling hot?"

Zhang Feng put down his tweezers, took a deep breath of cigarette, sandwiched between his fingers, and revealed a meaningful smile: "That's why I let you touch it, the side you touched The temperature is very high. According to the conduction temperature of iron, my side is already very hot. However, the temperature will never be as high as yours. The temperature is the same. As long as high temperature is generated at one end, it will be quickly transmitted to On the other side, the principles of the two are the same, do you understand now?"

The two seem to understand but nodded, and Ma Zhou even forgot the pain in his fingers.
