is not the case ...

"I was freezing. I was freezing. It's really frozen. The small basin was frozen. It's great." Li Hehua and Yu Hongyanzheng, you pulled my hand, I pulled your hand

It's all happy.

Xue Sihu turned around and twisted his eldest brother: "Big brother, it's really frozen!"

Xue Yihu just smiled particularly, and was obviously very happy.

Xue Yan also laughed. The family was happy.

Jiang Yue did not laugh, but went to find a bamboo piece, and then squatted in front of the pot, scraping the nitrogen crystal clear on the ice surface.

However, there are a lot of nitrogen crystal at the bottom of the large pot ice.

If the ice surface is reduced, the solubility of the nitrate decreases, the analyzed nitrogen crystals, the bottom and the middle, should be added to the addition.

Then, then

Xue Sihu noticed this, and immediately squatted down, and looked at it: "Is this too much nitrated? So these are not finished?"

Jiang Yue is not easy to say that your nitrogen is adding too much, and it is not good to say that as long as the nitrogen is sufficient, then it is frozen, and a certain amount of nitrate will be precipitated on the ice.

Said: "Maybe, maybe the fourth brother, we will add some nitrogen to try the next pot?"

"Okay!" Xue Sihu had no opinion.

"Four Tigers, really have you," Yu Hongyan laughed, "You said half a bag, it was really true, we are all at ease."

Knowing that they can make ice, they are all down -to -earth, Liu Guixia, Li Hehua, Xue Yihu nodded.

Xue Sihu immediately laughed: "I said it casually, because Xiao Yan said that he could reuse the nitrogen, and he was not afraid to get the nitrated gratitude, so I dare."

"Anyway, it is done anyway." Liu Guixia was really at ease, and his heart was very practical.

Jiang Yue is still a nitrated gratitude precipitated on the ice.

There is a big scoop next to it. It was not useful just now.

Xue Yan also went to find a bamboo slice, and then squatted down to help scrape it.

Liu Guixia also helped, scraped all the nitrate, put it in the big scoop. Before helping, I also found a clean cloth and covered the small pot.

You can't eat the ice.

Seeing the bottom of the large pot of ice, there is also a nitrogen crystal, which is quite a lot. A big scoop cannot be put at all. Li Hehua simply went to find a wooden barrel.

Put the scraped nitrate in the wooden barrel.

Xue Sihu and Xue Yihu went to find things to chine ice.

Seeing that the nitrate on the surface of the large pot of ice was scratched, they started to cut the ice, and took it out of the large piece of nitrogen in the bottom of the ice.

Xue Sihu was busy with this, and said, "I just added half a bag. Although there is no scales, it should be about fifty pounds. Now there are so many more, and we will add so much in the next pot.

"

It's not that ...

Jiang Yue wants to say.

This also includes the crystallization of the nitrated gratitude because of the decreased temperature.

But now I have been frozen once. If I did not freeze, I knew that the nitrics were less, so Jiang Yue didn't say anything.

Xue Yan naturally didn't say anything.

Xue Sihu didn't take the scale and said it directly with his hand, and I said: "Let's add 20 pounds to try the next pot."

Jiang Yue and Xue Yan followed him.

Liu Guixia naturally follow him.

It's just that Jiang Yue and Xue Yan both have a number. According to the size of this large basin, the amount of water installed, twenty pounds will definitely not be a ice.
