(Thanks to the support of the "Difficult to Be a Soldier" and "I want to pass through the chaos" monthly passes!)

The water was poured on the capacitor, and the high-frequency electricity amplified by the coil suddenly short-circuited, the water was electrolyzed, hydrogen and oxygen were generated, and under the action of the electric spark, a slight explosion occurred, Wang Qinian was startled, and Xiaoshuang was also so frightened that she fled back to her hut quickly, secretly watching this qiē, she didn't understand, how could there be an explosion.

Wang Qinian really didn't expect that Xiaoshuang meant to be joking, there was no malice, so his spirit god did not call the police, he was startled, and then turned on the light, and found that a qiē was very wolf, he dared to turn off the switch, looked at a qiē in front of him, and was about to get angry, and suddenly he laughed.

It turned out that he thought of the electrolysis of water, isn't this the electrolysis of water, and simply made the electrolysis of water.

He rearranged the real yàn, the equipment was insufficient, it was difficult for him, he was busy here, Xiaoshuang felt very strange, why didn't there be any movement, could it be that the lich was doused to death by a glass of water, it was impossible, the contract was fine, he was fine, he was not angry, it was strange, and slowly she stretched out her head.

Seeing that the lights in the room were bright, she couldn't hold back her curiosity, flew out, went to the door of the real yàn, turned her head in, and found that Wang Qinian was busy in it, erecting two long glass tubes, the two pipes are connected to each other, there is a metal wire above the tube that extends into the water, and there is a tube on it to export the gas to the gas collection cylinder, the gas collection cylinder is immersed in water, the bottle mouth is facing down, and the bottle is full of water.

As soon as she flew in, Wang Qinian pointed at her hand, she was frozen in the air, and it was impossible for her to speak. Wang Qinian didn't look at it, closed the switch, and the water began to bubble, but the speed was very slow, Wang Qinian patted his head, added a little sulfuric acid to it, and the blister suddenly became violent, and after a while, the drainage method collected gas.

Wang Qinian turned off the electric switch before he pointed with his hand. Lift the small double fixation method. Xiao Shuangyi regained his freedom, and said angrily: "Dead Lich, Stinky Lich, set people in the air." What bad thoughts do you want?"

Wang Qinian smiled: "Don't fix you in the air." When I do real yàn. You are making trouble again, and this reality has a certain danger, for your own good. ”

The little pair flies to the top of the gas collector cylinder. He said, "What kind of gas is collected in here, and what's going on with the bubbling just now?"

"There's a very light gas in it, which I call hydrogen, and in the other bottle is oxygen, and water is made up of the elements of these two gases. Wang Qinian explained.

"The volume of these two gases seems to be only half the volume of the other, what is the reason?" Xiaoshuang found a strange problem again.

"It's not surprising that the composition of water is 2 to 1 in a ratio of hydrogen to oxygen, but that's just a guess, and I'm going to measure it accurately. Wang Qinian said.

"It's incredible that water is made up of hydrogen and oxygen. ”

"No, water should be made up of hydrogen and oxygen, not hydrogen and oxygen. Wang Qinian said that the dialogue between him and Xiaoshuang would not be good if others heard it, after all, hydrogen and oxygen have not yet been verified.

Xiao Shuang didn't care about this, pointed to the set of equipment and asked, "What kind of device is this?"

"This is the electrolysis device, which I call the anode connected to the positive electrode of the battery, and the oxygen precipitates from this electrode, and the cathode connected to the cathode of the battery is the cathode, and the hydrogen precipitates from this electrode. Wang Qinian explained in detail.

While explaining, he kept his hands and feet, busy weighing the mass of the gas, weighed it in connection with the gas collection cylinder, weighed it, wrote down the number, and temporarily refined two very thin leather bags with the skin of the monster, filled the two gases into it, and a miracle appeared, and the skin bag filled with hydrogen gas floated up.

Xiaoshuang's eyes opened wide: "What's going on?"

"Hydrogen is very light, with a relative atomic mass of only 1, which is one-sixteenth of oxygen, much lighter than air, and it is insoluble in water, so it is collected by drainage, and because it is light, it can float in the air. Wang Qinian said.

"In this way, if there is a large amount of hydrogen, is it possible to build a big balloon, and people and things cannot be hung under it? Xiaoshuang said, his eyes full of excitement.

"Xiaoshuang is very smart, it can be so, this kind of balloon doesn't need magic, anyone can use it, unlike magic, in fact, the mysteries of nature are endless, I suspect that magic is also a kind of natural mysteries. Wang Qinian pulled the rope and pulled the balloon down.

"Give it to me, give it to me!" called Xiaoshuang.

"What do you want balloons for?" Wang Qinian still gave Xiaoshuang, although many of his successors still use hydrogen, but he can continue to electrolyze water to get it.

"I'll show my Warcraft friends. Xiaoshuang grabbed the line, Wang Qinian remembered one thing, and said: "You remember, it can't be close to the fire, otherwise there will be a deflagration, which is very dangerous." ”

Xiao Shuangxi looked at the balloon diligently, the sky began to shine, she didn't eat breakfast, holding the balloon in her hand, and hurriedly flew into the mountains and forests, Wang Qinian shook his head, he thought of another gas, that is, helium, which is very rare on the earth, I don't know if there will be a lot here, but Wang Qinian doesn't have much hope, there are a lot of them in the stars, if there is helium, then the balloon is much safer.

Wang Qinian didn't eat breakfast either, he continued to be real, less Xiaoshuang, but no one interfered, although he knew the result, but he still meticulously finished, stretched the wooden strip with Mars into the oxygen, sure enough, the wooden strip burned, and the hydrogen was burned in the oxygen, got water, and tested the mixture of hydrogen and air with different concentrations, the explosion sound kept coming from the real yàn room, and finally got a safe range: the volume concentration of hydrogen in the air was 4.0%~75.6% When the hydrogen concentration is less than 4.0% or greater than 75.6%, it will not explode even if it encounters an ignition source.

The sound of the bang bang bang attracted Jessica's attention, Jessica came to Wang Qinian's house alone, and when she saw that the door was open, she came in, and saw Wang Qinian doing the explosion, and the bags exploded one by one, and felt strange, so she said, "Good morning, what are you doing?"

"I'm doing a hydrogen deflagration. ”

"What kind of gas is hydrogen?" asked Jessica.

"Hydrogen is acid poured on metal to produce a gas, the alchemist called it the air that can burn, I call it hydrogen, it means that it is very light, I did the electricity last night, Xiaoshuang poured water on the instrument, I found that water can be broken down by electricity, I call this phenomenon electrolysis, the electrolytic products of water are hydrogen and oxygen, I am believing in testing the properties of hydrogen. Wang Qinian said, and did not ask Jessica to sit, Jessica was also used to it.

The two of them stood here, discussing the real yàn phenomenon, and after a while, Wang Qinian finished the real yàn, and when he saw Jessica still standing, he was embarrassed to say, "Look at you, go and sit in the room." ”

"You haven't eaten breakfast yet, have you?" said Jessica.

Wang Qinian smiled embarrassedly: "I didn't eat it, you wait a minute, I'll get it." ”

"Forget it, let's come with me, why don't you get married, Tina who came last time was good. Jessica rushed to do things, baking bread and cooking cereal.

"I'm not going to get married, I'm all about magic, and besides, I'm in my forties now, and Tina is only sixteen, so I can't delay anyone else. Wang Qinian said.

"It doesn't matter if a mage is older, besides, once you enter the legend, you will live a long life. Jessica said.

"Let's not talk about this, I'm going to Sky City tomorrow, I haven't been there for a long time, let's see what kind of progress they have built. Wang Qinian changed the subject.

Jessica saw that Wang Qinian had changed the topic, knowing that he didn't want to talk, so she smiled and brought the baked bread and cereal, Wang Qinian asked, "Do you want to have some?"

"No, I've already eaten it, if it weren't for the constant loud noises coming from your house. I won't come to see it, I can't imagine that you have taken a cue from a real accident. When Jessica said this, she suddenly heard someone shouting at her outside, but far away, Wang Qinian also heard it, it was Jenny's voice.

"Jessica, are you there?"

Wang Qinian's ears are very sharp, and when he heard this voice, Wang Qinian smiled and said, "Your precious apprentice is here." ”

Jessica also smiled: "Okay, I told Jenny yesterday that I wanted her to help me get real, but she came early, and I should go, I hope to see your paper published as soon as possible, so I won't disturb you to do it, and I'll call you tomorrow morning." ”

Jessica went out, Wang Qinian had breakfast, threw the bowl casually, fell into the sink, recited a spell, the faucet automatically turned on, the dishes and forks moved automatically, and after washing, they automatically jumped into the cupboard.

Wang Qinian sorted out the number to see that there were still some deficiencies, and was about to do it again, when Jenny came, followed by a person, whom Wang Qinian knew, was Reinhardt von Royenkram.

"Mr. Wang, this is my brother Reinhardt. Jenny said.

"I know, last semester's auditor, you are already a magician, why did you listen to it from the lower grades?" asked Wang Qinian.

"Dear Professor Wang, I just studied under a wild magician when I was a child, and soon he left, I found that I was very deficient in all aspects, I happened to travel to Huolin Qiaoton, I heard that Professor Wang cultivated magic and martial arts, and it happened that my sister also came here, so I cheekily begged my sister to bring me over, to meet Professor Wang, I listened to your class last semester, and it was very good, and it inspired me a lot. Reinhardt said politely.

"Sit down, you're welcome, I'm just one step ahead, you're still young, the world of magic is vast, it's not too late to work hard. Wang Qinian said with a smile.

The two sat down, Wang Qinian waved his hand, a cup of coffee appeared in front of the two, the two took a sip, Wang Qinian saw Reinhardt's eyes flashing slightly, as if frowning, but full of praise: "Good tea!" and Jenny didn't feel anything.

Wang Qinian smiled slightly, he knew that his coffee was not good, he didn't pay attention to this, and Reinhardt obviously paid attention to this, he didn't want to say it clearly, so he had to praise it against his will, and he was sincere in magic. (To be continued......)
