"How to distinguish?" Asked Leng tomorrow night.
"The ignition point of glass and diamond is different... It must be distinguishable." The girl said immediately.
Tomorrow night said coldly, "Yunwei, tell her whether this method is feasible."
It's really going to be left to Yun Wei to do all the things that offend people.
Yunwei sighed and said, "diamonds are simple carbon with low ignition point and melting point. If they are burned by fire, diamonds can easily be burned away. Moreover, glass is amorphous. It can't be said that it has a fixed ignition point and melting point. It only has a melting range. Therefore, when burned by fire, both diamonds and glass may be burned at the same time. Obviously, it's not easy to distinguish between glass and diamonds. "
The girl gave Yunwei a resentful look. Obviously, Yunwei's answer made her answer look so fragile and vulnerable.
The cold voice of tomorrow night said, "the ignition point of diamonds is at least 600 degrees Celsius. Whose alcohol lamp can burn out a high temperature of 600 degrees Celsius? Out! "
The girl was stunned. Although she was unwilling, she had to go out with her subordinates who were cold tomorrow night.
Lisa Fang glanced at Yunwei uncomfortably. The cold tomorrow night made Yunwei sing in unison with Yunwei, which made Yunwei look like an examiner instead of taking the exam.
The candidates' continuous answers can't satisfy the cold tomorrow night.
The rest of the candidates did not dare to answer again for a moment, for fear of becoming the one who was immediately said "out" by tomorrow night.
Tomorrow night Leng snorted with satisfaction: "well, if no one can answer this question again, the exam will be finished in five minutes. Everyone is out! "
Everyone look at me, I look at you. Obviously, the arbitrary method of tomorrow night cold makes people feel choked, but who can change the idea of tomorrow night cold?
At the moment, everyone turned their eyes to Yunwei and looked at Yunwei for help. It seems that at least Yunwei still has a way to prevent everyone from being destroyed.
Yunwei took a look at the plate mixed with broken diamonds and broken glass. In fact, with her eyes, the difference between broken diamonds and broken glass is still very large. Her eyes can fully see the detailed texture structure of diamonds and glass, and can easily distinguish their differences.
But she can't tell it's cold tomorrow night. Can she see through diamonds and glass? He could never believe it when he told him that it would be cold tomorrow night.
It's not just him. Maybe no one can believe Yunwei's eyes. Can you directly distinguish the authenticity of any real jewelry and diamond with the naked eye?
After all, there is no such person in the world with such eyes.
She had to find another way.
It's cold tomorrow night. I don't want to stay here anymore. I said to my subordinates, "there are two minutes left. You watch them. Let me know the result in two minutes. "
"Less cold... Let me try." Yunwei stood up and said.
Tomorrow night is cold. She was going to leave. When she turned around, Yunwei had already opened her mouth.
He paused and turned back, "you only have two minutes."
"Good." Yunwei turns and walks to the place where the teacup is placed in the conference room.
She chose a large glass teacup, put more than half a cup of water in it, and then poured the broken drill and broken glass into the water.
With a cold hum tomorrow night, does she want to distinguish diamond from glass by the different refractive index of diamond and glass?
