im not all that knowledgeable in chemistry, so im stuck here thinking how is it that the coal is burning in a liquid!!? i know oxygen is important in lighting a fire but still the fact that it is liquid and burns it, thats crazy to me

@Judicial78 9 жыл бұрын

That's because you are associating the fire going out with the liquid, when in reality the reason a fire goes out when covered in liquid is partly because it's smothered. Liquid oxygen, on the other hand, cannot be smothered because it IS oxygen. Try not to think about liquids as anything more than a state in between gas and solids.

Would it seem reasonable to say that the "undulating" change in brightness is actually the oxygen managing to suffocate the charcoal? Remember we ultimately have a fuel-to-oxygen ratio to keep up.

@NBAasDOGG 11 жыл бұрын

This is actually science at it's lowest level! Very good for childeren to understand how oxygen works :)

@ObliteAbyss 11 жыл бұрын

Because the oxygen itself isn't actually a fuel, it's an oxidising agent - Something which allows or causes another substance to release energy. The more oxygen present, the more energy can be released, so the brighter and hotter the flame on the charcoal. Also because there's more present, less initial energy is needed to kick start the reaction, meaning the temperature of the charcoal when dropped was sufficient to cause a flame when it came into contact with the higher oxygen concentration.

And to add to my previous comment: you can't do stuff like this for longer periods of time because it will lower the temperature of your mouth causing the vapor emission to decrease. You'll get frostbitten if you're too daring. The Leidenfrost effect can be observed in mundane situations as well; just heat a skillet to a high temperature and pour some water on the hot skillet. You'll see that the water doesn't instantly evaporate but rather "floats" on the surface of your frying pan.

Yes, exactly. The sun is "fusioning," which should be a word, but I don't think that it actually is. Fire is a very special state of matter. It's a plasma, but not a plasma. Material undergoing combustion becomes magnetically charged for a time. I saw a great demo of a flame on a burning candle in the presence of an electric field. The flame was split, according to charge. When extinguished, the resulting smoke remained electrically charged. Very interesting!
