Chapter 241
"You're right. To a certain extent, highly perishable substances such as feces and garbage can indeed explode, and the power is not small." After hearing Fang Jue's words, Ma Chao really recognized it seriously. What he just said.

"Ah... is it really possible???" Fang Jue was shocked when he heard Ma Chao's words.He never expected that what he said casually directly revealed the essence of the explosion.

"That's right, you are a college student, so you should know to some extent that after the object rots, various chemical gases such as oxygen, nitrogen, hydrogen, carbon dioxide, methane, ammonia, and hydrogen sulfide will be produced, right?" Ma Chao saw Fang Jue looked in disbelief, but patiently began to explain.

"Yes, I know this. I learned it in chemistry class." Fang Jue heard it and confirmed it after a little reflection.Zhang Boxin next to him also nodded quickly, affirming this.

"Then how much of the gas produced is combustible??" Ma Chao asked rhetorically.

"Eh.........in this, I only remember that hydrogen gas is flammable. I don't remember the others very clearly." Fang Jue said with an embarrassed face.After all, he is from the Department of Agriculture, so he is not very clear about the detailed characteristics of these chemical gases.

"Yes, hydrogen is a combustible gas, and both hydrogen sulfide and methane are combustible. Like the very foul smell of rotten eggs we smelled before, it is the smell of hydrogen sulfide. And it will produce this It is very common in daily life, such as toilets." Ma Chao followed Fang Jue's words and continued.

"But, Brother Ma. If you say it like this, wouldn't there be a fire and explosion in the toilet? But we haven't found any explosion in the toilet on weekdays." Fang Jue didn't say anything this time, but It was Zhang Boxin who asked the question.

"Hehe, you are right. In daily life, there are very few or even no cases of toilet explosions. That is because the concentration cannot reach the level. Taking methane as an example, only when it reaches at least 5.00% in the air After the ratio, the minimum explosion requirement is reached. The upper limit is a little more than 15.00%, which is less than [-]. After exceeding this ratio, limited by the oxygen problem, no explosion can be produced at all, and it will only burn slowly. "

"But if you think about the environment where the toilet is located, it is basically in the open air, with excellent ventilation. In this environment, how can it reach the lower explosion limit of 5.00%. Therefore, it is normal to not be able to see it."

"It's different here, it's basically a confined space, and those fertilizers that are retting will continuously produce combustible gases such as methane and hydrogen sulfide, and the concentration required for the explosion will soon be reached. So , as long as there is such a small spark at the right time, it will definitely cause an explosion." Ma Chao explained.

"So, the explosion at the beginning was because the electric spark generated when the light was turned on ignited the methane and other combustible gases in the air, so the explosion occurred!!! It was only because the light switch was not underneath, so it was also No one can see the actual situation, nor can they find the evidence of the explosion! Because the evidence was consumed with that explosion." Fang Jue instantly understood everything about the explosion, and said excitedly.

"That's right, that's what I guessed too. And, I think that later on, some sensible person came over to check the details and determined the cause of the explosion, so the power supply here was cut off. , is to prevent this from happening again. And, it should not be just a remedial measure of cutting off the power." Ma Chao shrugged.

"That's right, there are indeed more than this one. Boxin, do you still remember that this place was remodeled before it was used?" Fang Jue said to Zhang Boxin.

"Ah, I remembered. At that time, a ventilation renovation was carried out here, but the scale of the project was not large, so the only people who knew about it were the people from the Department of Architecture, except our Agriculture Department. No Wrong, Brother Fang, the ventilation duct you closed some time ago was installed during the renovation." Zhang Boxin said after thinking about it carefully.

"Yeah, it's thanks to closing that ventilation duct that we've been able to hide until now." After hearing what Zhang Boxin said, Fang Jue nodded and said happily.

"So, do you still have any doubts now??" Ma Chao asked with a smile when he saw that both of them had already understood what was going on here.

"No, thank you Brother Ma." "Brother Ma, you know so much!!!" The two thought about Ma Chao and thanked him for explaining the truth clearly, otherwise, the two of them would not have understood it at all. Case.

"You're welcome. After all, if you don't know what's going on here, it won't be good if there is an accident. I'm still counting on those flammable gases to carry out the assassination." Ma Chao said.

"Yeah, that's right. So, Brother Ma, what are we going to do next?" After hearing Ma Chao's words, Fang Jue asked about what to do next.

"The next thing...the next thing to do is to eat, sleep, and refresh yourself. Starting tonight, the three of us will be very busy, and the workload ahead is not small." Ma Chao said .

"Don't worry, Brother Ma, as long as there is a place where we can help, you can just ask to make arrangements. The saying that everyone is responsible for the rise and fall of a country has been firmly rooted in the day I started studying. My heart is broken." Fang Jue said seriously.

"Don't worry, I won't make it easy for you. Just don't complain when the time comes, haha." Ma Chao said to Fang Jue relaxedly.

"Yeah. It's just, Brother Fang, we still have a question." Fang Jue suddenly said a little embarrassedly after thinking of something.

"Huh??? What's the problem???" Ma Chao asked curiously. In his opinion, there is nothing left now.Just need to do the next civil work, where is the problem.

"That's right, we have nothing to eat. What can you do? Brother Ma." Fang Jue said helplessly.People are like iron rice is steel, if they don't eat one meal, he will be so hungry, if they don't eat three meals, his heart will feel cold.

"Er... this problem, he is not a problem." Ma Chao looked at Fang Jue with a strange expression and said.
