Question

if there is an atomic bomb that is dropped in the sea water and blasted then there be rise in the temp of sea water the hydrogen and oxygen will be seprated. There will be a huge amount of heat produced. and that hydrogen in presence of oxygen will catch fire. and the atomic bomb will be a chain reaction. that will be continuous. . so what actually will happen. . .??????
i need a answer. Still confused

Answer 1

I'm not entirely sure what you're asking...

I think you're trying to ask if the heat energy generated by an underwater nuclear blast would be sufficient to separate water molecules into their component parts and then ignite, causing some kind of additional explosion.

I don't really know the answer, but my instinct says "no" or, if this phenomenon did occur, that it would be relatively minor compared to the primary explosion.

Here's an article from Wikipedia that has some general explanation of underwater explosions: http://en.wikipedia.org/wiki/Underwater_explosion

Can you maybe try to re-phrase your question?

Answer 2

No, no, no. lol!

First, the chemical reaction has a net energy effect of zero as far as water is concerned. Any energy used to hydrolyze water (endothermic) will then get that much energy back (maybe even less a little due to radiant heat losses) when the hydrogen and oxygen burn to form water. In other-words, water is at a the low-energy level, like a un-stretched tension spring. Stretching it out requires work, and you get that work back when you release it. This it directly the result of the laws of thermodynamics.

Second, heat alone doesn't "cause" what could be considered "consistent" hydrolysis (decomposition reaction converting water into hydrogen and oxygen, which is endothermic, absorbs energy). What really gets hydrolysis going is direct current voltage. I know this from experience, you can't hardly produce any oxygen or hydrogen using straight alternating current voltage. You have to invert it using four diodes so that the current only flows one way. And even then AC is bad because it keeps bouncing the voltage. For any electrolysis decomposition reaction you want to have HIGH voltage and keep it DC and leveled out as much as possible, so you get a consistent, steady flow of the ions. And finally the anode and cathodes are needed for you create a "go to" location for the ions. Given the extreme swings in pH when the ions really start to flow, graphite (a pure form of carbon) is needed so that your anode and cathode don't just corrode away and ruin the flow with their inefficiency.

Finally, as far as they hydrogen in fusion-powered H-bombs, this hydrogen is RAPIDLY consumed by the fusion reaction. Any chemical reaction is negligible in sheer comparison. The scale of energy contained in nuclear reactions is truly mind-blowing, enough that the scientists that first discovered it thought for sure it was a calculation error.



Now an atomic bomb igniting a forest, house, or people on fire? Yes, there's an exothermic release of energy when these things burn. Indeed, heat the human body up enough and it does burn (aka. cremation). Burning is combustion, an exothermic reaction (releases heat from the system into the environment).

Here's a video of an 8-kiloton underwater nuclear blast:

thank you.
Satisfied with answer :)
