"What?"

Now it's not just Wang Qi, even Wang Qi is blindsided.

And to make money by selling ice cubes, and to make them not know that this is ice? How is this possible?

Ye Ming smiled mysteriously, lowered his voice and said a few words to Sister Wang Qi, Sister Wang Qi's eyes became brighter and brighter the more she listened, and finally Wang Qi slapped Ye Ming's shoulder and said, "You guy has too much bad water, but I like it!" ”

...

"Miss, you're here." Looking at Wang Qi who walked in, Wang Li, who was doing carpenter work, hurriedly saluted.

"Well, Uncle Wang doesn't need to be polite, I'm here to ask you for help this time." Wang Qi said.

"If the eldest lady has something, I will definitely do it."

Wang Li is a family in Wangjia Village, he has some carpenter's skills, although it is not exquisite, but most of the carpenter's work is difficult for him, and he can barely make a living with this craft, and his living situation is considered to be at the upper middle level in the village.

"Uncle Wang, I want to ask you to build a wooden box, this is the drawing, you can take a look, there is no problem."

"Boxes?" Wang Li was stunned for a moment, then took the drawing, and understood it after just one glance.

This is a very ordinary wooden box with a lid, but this lid requires that it can be taken down, and it is also required to be as tight as possible after the lid is covered, which is not difficult for Wang Li as long as the accuracy is improved.

But Wang Li is curious, isn't the box used to hold things, why is it made so tightly?

Although he was curious, he was not the one to ask questions, so he nodded and said, "Don't worry, Miss, this is very easy, I can make it for you in two hours, if you are in a hurry, I will do it now, just one hour." ’

"Then it's going to trouble Uncle Wang," Wang Qi said with a smile, "But don't be too anxious, I'll come and get it in two hours." ’

In the house, Ye Ming and Wang Qi are doing it, of course, this move is not a fight, speaking of fighting, Ye Ming, who has no ability, is not Wang Qi's opponent, they are tearing the quilt now.

That's right, it's tearing the quilt, but it's not Wang Qi's sister's quilt, it's Ye Ming's quilt.

The Wang Qi sisters made some preparations in order to rob their relatives, including preparing brand new clothes and quilts for Ye Ming, of course, that's all, after all, they are not ordinary poor, and the reward obtained by the thief can also buy these things.

Wang Qi looked at the brand-new quilt being torn apart, and said that it was fake not to feel distressed, but when he thought of the business he was going to do, he gritted his teeth and accompanied Ye Ming to do it, tearing the big quilt into several smaller pieces of cloth and larger pieces of cloth.

"Wait for these cloths to be taken out and washed properly," Ye Ming said: "After the box is ready, these smaller pieces of cloth will be spread inside the box, and the larger pieces of cloth will be covered on the outside of the box, and the more you cover, the slower the ice will melt." ”

Wang Qi nodded, but immediately felt wrong, she raised her head to look at Ye Ming, and asked curiously: "No, isn't the quilt used to cover for warmth, cover it on the ice cubes, wouldn't the ice cubes melt faster?" ”

Ye Ming glanced at Wang Qi and sighed in his heart. This is ancient times, and he doesn't know a lot of basic common sense, and he needs to explain it every time.

"Wang Qi, let me ask you a question first, in your heart, do you think that the quilt can only be used for warmth? Can't do anything else? ”

"yes, what else else could you do?" Wang Qi said as a matter of course.

"Okay, then let me ask you again, under what circumstances can the quilt be warmed?"

"Of course, you can warm up while sleeping, what's your problem, it's too simple."

"Don't worry, listen to me continue to ask," Ye Ming smiled and said: "You also said that the quilt is only warm when people are sleeping, so is the quilt warm when people are not sleeping?" ’

"Of course..."Wang Qi just wanted to say that of course there is, but she immediately reacted, it seems that the quilt has always been cold when no one uses it!

"Of course. . . Of course not, no one uses it, how can it be warm, it's always cold. ”

"So, the question is, why?" Ye Ming asked with a smile: "Why is it warm when someone uses it, and cold when no one uses it?" ”

Wang Qi was immediately stopped by this question.

yes, why?

"Xianggong, could it be that the reason for the warmth of the quilt is not the quilt itself, but the people?" Wang Qi walked in from the outside and said.

"Go on."

"Xianggong, is this the reason why the quilt is warm, which means that the quilt absorbs heat, and the heat quilt itself does not have, and the bed does not have it, the only person who has heat is the person, it is the person who transfers the heat on the body to the quilt, so that the quilt will be warm?"

When Wang Qi heard his sister's words, he immediately figured it out: "Yes, Ye Ming also said earlier, the reason why summer ice melts is because it absorbs a lot of heat, and since ice can absorb heat, then the quilt can naturally absorb heat!" ’

"This is just one of them," Ye Ming added: "In addition to absorbing heat, the quilt can also keep warm, otherwise it will disperse immediately after absorbing heat, and what effect will we have when we sleep with the quilt." ”

Sister Wang Qi nodded in agreement, but Wang Qi immediately asked, "Then since the quilt can absorb heat and keep warm, why do you say that it can stop the ice from melting?" Isn't that a paradox? ’

"It's not a contradiction," Ye Ming said: "Look, since the quilt can absorb heat and keep warm, as long as you don't send heat to it, how can it absorb it?" Just like the quilt on the bed, why is it cold for a day, whether it is the bed or the quilt? ”

"Uh..."Wang Qi heard Ye Ming say this, and he understood a little: "What do you mean... If you don't send heat to the quilt, but send it cold, the quilt will not only not keep warm, but keep it cold? ”

"That's right! That's it! Ye Ming said with a smile: "In the final analysis, the quilt plays a role in isolation, the reason why we cover the quilt for warmth is to use the quilt to isolate the cold outside and protect the heat emitted by our body, the same reason, to cover the ice with a quilt is to use the quilt to isolate the heat outside and protect the cold of the ice, but unfortunately the quilt is not sealed, there is always some heat that will slowly come in, otherwise, the ice will not melt." ”

"Sealed? What seals? Wang Qi heard another new word.

"Eh..."Ye Ming blinked and said, "Don't worry about this, this question is even more profound, and you don't understand what I said."

Wang Qihu glanced at Ye Ming suspiciously, and then stopped worrying about this problem, and said: "You mean to cover the inside and outside of the box with a quilt, and then put the ice inside the quilt, so that the ice will not melt?" ”
