Everybody knows, there is oxygen in the aerospace of vast boundless. So, does sun combustion need oxygen? Without oxygen, why can the sun burn? Fasten urgent, the scientist will tell you right answer. (the picture comes from IC Photo)According to Vicki the definition of 100 divisions, combustion is the object oxidizes quickly, produce light and hot course, its are oxidation constitutionally reductive reaction. Say combustion must not have oxygen to attend so, any glow, calorific, acuteness oxidation is reductive reaction, can make burn. (the picture comes from IC Photo)Should satisfy only produce acuteness oxidation the condition of reductive reaction, small it is hydric and OK to arrive combustion, magnesian in chlorine can burn in nitrogen; Carry oxidizer oneself to rocket motor greatly (like 4 oxidation 2 nitrogen) work in deep space. So OK and clear is, although do not have oxygen, combustion still can undertake. (the picture comes from IC Photo)The sun is a star that enrages composition by a large number of hydric helium, according to the notion that accepts generally now, the sun by in-house hydrogenous helium nuclear fusion, glow is calorific, oxidation did not happen on the sun reductive reaction, it is process of a physics only, so the sun did not produce combustion. (the picture comes from IC Photo)Arrive from earthly observation, the sun is acuteness " burn " the conflagration ball of the move, why is sun surface really OK does observation arrive structure of shape of many flaming blaze? (the picture comes from IC Photo)This is not arise by nuclear fusion directly, because the nuclear fusion of the sun produces interiorly core division only, external photosphere layer, chromosphere layer and corona layer or because temperature is insufficient, or because aeriform density is too low, nuclear reaction cannot happen. (the picture comes from IC Photo)With the most straightaway word for, it is line of sun magnetic field happens ceaselessly rupture, weigh couplet, magnetic develop attacks to be discharged afresh cloth, then is right plasma of tall electrical conductivity produces an effect in sun air, make its produce high-energy phenomenon ceaselessly, produce blaze shape structure. (the picture comes from IC Photo)Although the universe is medium,do not have oxygen so, the sun still can produce phenomenon of similar blaze flaming. Actually, sun surface combustion is false appearance only. To this, how do you look? (the picture comes from IC Photo)
