People in the Three Kingdoms, start to capture Jiangdong

Sun Ce is the prefect of a county at any rate, so he shouldn't be so shameless.

After all, this kind of thing can get the result after a little inspection.

Not necessarily.

Sun Ce can even kidnap them.

What else is there not to dare to do?

"If Gongda doesn't believe it, he can test it himself."

"Come on, bring the iron ball up."

Sun Ce smiled slightly, and ordered to the left and right.

Two iron balls were brought up.

One big and one small, exactly ten catties and one catty.

Obviously Sun Ce had already prepared.

Xun You looked at the two iron balls, and then at Sun Ce's expression of winning.

I feel a little unconfident in my heart.

"Am I really wrong?

No, it's impossible.

Everyone agrees that heavy things hit the ground before light things.

There is absolutely no way it could be wrong. "

Xun You fell into self-doubt.

But soon he became firm in his belief: "Look at my experiment and prove that I am right."

With the help of the soldiers, Xun You climbed onto the top of the carriage, and then began to conduct experiments.

As a result, the two iron balls fell to the ground at the same time.

"how can that be?"

Xun You showed an expression of disbelief.

Chapter 055

Jia Xu was surprised.

Just now he also felt that the heavy iron ball hit the ground first.

Unexpectedly, they landed at the same time.

Why is that?

more importantly.

Sun Ce seems to have known this result a long time ago.

"It seems that the new Lujiang prefect is not simple."

Jia Xu narrowed her eyes and looked at Sun Ce calmly.

A trace of curiosity rose in his eyes.

"Gongda, can you admit defeat?"

Sun Ce asked Xun You with a smile.

"I surrender."

Xun You opened his mouth, but finally admitted that he had lost.

"it is good."

Sun Ce nodded in satisfaction.

He still admired people like Xun You.

Some people obviously lose and still don't admit it, and they may say that he cheated.

If Xun You is this kind of person.

Sun Ce might kill him on the spot.

After all, no matter how much wisdom there is, it is useless if the character is not good.

"Then comes the second question."

"Why does gold sink in water but not wood?"

Sun Ce asked.

"This......"

Xun You was dumbfounded and didn't know how to answer.

Jia Xu next to him frowned and thought about it.

turn out......

I don't even know why.

"why?"

Jia Xu cast her eyes on Sun Ce.

Seeing his calm appearance, I couldn't help thinking secretly:

"Does he know?"

Half a stick of incense time passed.

Xun You still didn't answer.

Sun Ce urged, "Don't you think about Gongda's answer yet?"

"Because, because gold is heavier than wood."

Xun You falters his way.

"You are wrong again."

Sun Ce smiled slightly:

"Can a catty of gold weigh more than ten catties of wood?

But ten catties of wood can float on the water, but one catty of gold will sink in the water.

So it has nothing to do with weight. "

After hearing Sun Ce's words, Xun You knew that his statement was untenable.

But he hasn't lost yet.

"Prefect Sun, can you tell me why?"

If Sun Ce can't answer or answer wrong.

Then this problem does not count.

It's a pity that Sun Ce didn't give him a chance at all.

The corners of his mouth raised slightly, and he ordered left and right:

"Come here, bring up the bucket, the gold, and the wood."

Not long after, these three things were placed in front of the three of them.

With gold in his left hand and wood in his right, Sun Ce smiled at Xun You and said:

"The reason why gold sinks in water and wood doesn't is because they have different densities.

Density is the mass of an object divided by its volume.

Indicates the ratio of mass to volume of a substance.

Density is one of the properties of matter.

Each object has a different density.

Gold has a density of 19.32 and water has a density of 1.

The density of wood is 0.2, 0.9 and so on.

There are also some woods with densities of 1.1, 1.5, etc.

But most wood has a density less than 1.

Gold has a density greater than 1 that of water, so it will sink in water.

Wood has a density less than 1, so it floats on water.

Gongda, do you understand? "

"Boom."

Sun Ce's words exploded in Xun You's mind like thunder.

His heart suddenly became clear, and he realized the truth.

"It is so, it is so.

Is this why there are wooden ships in the world but no iron ships? "

Xun You murmured.

Jia Xu was equally shocked.

He remembered that there was a kind of wood in Liangzhou, which was so heavy that it could sink into the water.

I used to think it was special, but I didn't know where it was special.

Now I finally understand.

It turned out to be because of the density.
