"Reporting to the dean, they are in the laboratory."
The student said with a respectful expression.
Zhang Feng thanked him and walked to the laboratory. The laboratory was a place for everyone to do experiments. Ma Zhou and Hao Chujun would usually be here.
As soon as he entered, he saw the two of them lying on the table with glass bottles in their hands. He didn't know what they were doing.
"Ma Zhou, Hao Chujun, what are you doing?"
Zhang Feng asked curiously.
The two of them turned their heads and looked at Zhang Feng with surprise. "Benefactor, why are you here?"
After that, the two of them quickly put down the glass bottles in their hands and walked to Zhang Feng.
"I have something to tell you."
Zhang Feng looked at the two of them and smiled faintly. "I need you to develop a device for heat transfer."
The two of them frowned and looked at each other in confusion.
"Benefactor, what do you mean? Can you explain? "
Ma Zhou scratched his head and didn't understand.
Zhang Feng glanced at the two of them and explained patiently. "Simply put, it is the flow of high temperature gas or the gas composition changes and the interaction between the gas and the object. What kind of changes will happen when an object encounters a strong airflow? For example, why can a kite fly in the sky? It is affected by the airflow. Now I need you to make a device to transfer the heat to the other side."
"This …"
Ma Zhou and Hao Chujun were even more confused after hearing this.
Zhang Feng didn't blame the two of them. Instead, he continued, "Actually, this isn't very difficult. Go and prepare an oil lamp, tweezers, wire, and paper. I will show you the experiment."
When the two of them heard that there was an experiment to watch, they immediately ran off.
After a while, the two of them brought the oil lamp, tweezers, wire, and paper over and placed them on the table.
Zhang Feng took out a lighter and lit the oil lamp. Then, he took out a cigarette from his waist and flicked it over the oil lamp. He took a deep breath and exhaled the smoke. He looked at the two of them and said, "Watch carefully."
"Cough cough … Okay, benefactor."
Ma Zhou covered his mouth and nose and said with difficulty. Obviously, the smell of the cigarette choked him.
Hao Chujun wasn't any better. He pursed his lips and nodded vigorously.
Zhang Feng smiled and shook his head. He put the cigarette in his mouth and picked up the paper and wire with both hands. He put the wire through the paper, leaving a gap of two centimeters in the middle.
After doing all this, he used a pair of tweezers to clamp one end of the wire and placed the other end on the oil lamp to heat it up.
After a while, the iron wire turned black. Then, it slowly turned red until it was completely red.
"It's red. Benefactor, it's red."
Ma Zhou exclaimed excitedly.
For someone like him who was obsessed with academics, this was probably the only thing he was interested in.
"I know it's red."
Zhang Feng was grinning with a cigarette in his mouth. His words were a little unclear.
After saying that, he took the iron wire from the oil lamp and looked at Ma Zhou seriously. "Feel the difference between the two ends of this iron wire."
"Touch it?"
Ma Zhou was a little confused.
Although he was simple-minded, he wasn't stupid.
Wouldn't he be scalded to death if he touched it?
He shook his head to show his refusal.
Seeing this, Zhang Feng showed a harmless smile. "Listen to me. I'm doing this for your own good. You can only experience the results of the experiment by touching it. After experiencing it, you can remember it forever. Besides, this iron wire isn't very hot. Look, I'm also holding it, right?"
Ma Zhou glanced at Zhang Feng with a little suspicion. There was a huge struggle in his heart. In the end, he stretched out his hand.
"Hiss …"
A sudden pain hit him, and he jerked his hand back.
He looked back and saw a black mark on his hand.
Ma Zhou glanced at Zhang Feng with disdain.
What happened to not being hot?
It was all a lie.
Who would believe you?
Zhang Feng didn't know these thoughts. He handed the iron wire to Hao Chujun.
"Do you want to touch it?"
Hao Chujun quickly waved his hand and took two steps back. "I'll pass. Ma Zhou will remember the results of the experiment."
Zhang Feng nodded with a faint smile and looked at Ma Zhou. "Ma Zhou, in fact, I'm helping you. You see, in the future, when you see the scar on your hand, you will think of this experiment. Now, tell me how you feel about this experiment."
Help me?
Ma Zhou rolled his eyes.
However, on second thought, it seemed that there was nothing wrong.
It was also a good thing that he could remember this experiment forever.
He touched his hot hand, endured the pain, and said seriously, "Benefactor, I don't feel anything. I'm curious about one thing. Why don't you feel hot, but I feel hot?"
Zhang Feng put down the tweezers, took a deep puff of the cigarette, and held it between his two fingers, revealing a meaningful smile: "This is why I let you touch it. The side you touched was roasted by fire, and the temperature was very high. According to the speed of iron's heat conduction, my side was already very hot, but the temperature would never be as high as yours. The same principle applies to the temperature. As long as one side produces a high temperature, it will quickly be transmitted to the other side. These two principles are the same, do you understand now?"
Do you understand now? "The two nodded. Ma Zhou even forgot the pain in his fingers.
