["수소가 폭발했습니다

,"수소는 무색무미의 기체로, 5도씨에서 폭발이 일어납니다. 자료는 너무 포괄적이기 때문에, 수소가 닫힌 용기에 있고 다른 기체가 없고 오직 수소만 있는 경우 5도씨에서 �爆炸是否会爆炸?不需要空气参与,是否可以这样理解?谢谢,加分

"rovers를 이용해 수소 폭발을 활용했습니다.

"수소의 폭발 극한은 4.1%~75.6%(體积浓度),意思是如果氢气在空气中的体积浓度在4.1%~75.6%之间时,遇火源就会爆炸,而当氢气浓度小于4.1%或大于75.6%时,即使遇到火源,也不会爆炸。

"수소가 없는 매체로 발생하는 폭발은 물리적 폭발이며, 不是由燃烧引起的体积剧烈膨胀,而是随着温度的升高体积不断增加,但密闭容器导致体积增加受限,于是压力会逐步升高,当压力升高到压力容器无法承受时,就会发生容器爆裂或爆炸。楼主讲的应该是达到一定温度后氢气的分解爆炸吧?我查了下,氢气的分解温度要在150℃以上了50℃不会造成分解爆炸的

"5℃应该是氢气的燃点,必须有氧气的情况下才能燃烧,氢气储罐为正压,即使发生泄漏被点燃也只会喷火而不是爆炸。除非储罐受到热辐射压力急剧上升,导致物理爆炸,温度每升1℃,压力上升5bar

"수소가 4.1%~75.6%의 浓度时与空气混合,或占18.3%~51%易引爆。氢气的着火点为555 °C。

"지구的大气助燃,然后点燃的,不是纯氢气点燃!!!

"555℃肯定不够; 化学反应爆炸需要助燃物参与; 物理爆炸看容器耐压情况如何; 结论:555℃发生爆炸说法不严谨,不完整。
