how does an atomic explosion actually stop?

Question

I mean, what makes the reaction slow down and how is that energy changed over time?

Answer 1

Well, you have to remember that the atomic explosion still requires an explosive -- the uranium or plutonium in the core. The explosion itself is an uncontrolled fission reaction, generating massive pressures and temperatures in a fraction of a second. Hard to say for absolutely certain, since no instruments made by humans are capable to of withstanding those forces long enough to give us any meaningful numbers, but the fuel is either completely consumed in the explosion or is blown far enough apart that it no longer can sustain those temperatures -- the fission chain reaction is most easily sustained when all the fuel is close together, so that all the particles flying out from each fission has the best chance of impacting more fuel.

Answer 2

The explosion is through the explosive combination of fissionable material. Putting a conventional explosive around Uranium 235 or plutonium to put it into a critical mass quickly. As a critical mass, the neutron dischangd split the atoms, producing two more neutrons which split more atoms and so on...very quickly with huge release of energy.

The fissionable material is physically separated as it blows apart and the neutrons don;t affect it anymore

Answer 3

assuming all else is equal, the explosion will stop when the chain reaction canno be sustained.

For the chain reaction to be sustained, you need for the neutrons produced by the fission of each nucleus (in the case of a fission nuclear bomb, such as plutonium) to be able to find another atom to split. But when the material gets too spread out (which typically happens at the time of the explosion), this cannot happen anymore.

Answer 4

Atomic explosions are the chain reactions that occur when highly compact unstable molecules are released, colliding violently together. This all happens very fast.
Its like a 900 trillion extremely tiny flying guns that keep shooting each other. When one gets hit, it goes flying and shoots off shots even quicker, hitting more flying guns, which by now are zooming around at incredible speed and firing a million shots a second. The flying guns and the cloud of bullets expand at an exponential rate. When the flying guns get low on bullets, they slow their rate of fire until they run out of bullets and start firing pieces of themselves until ultimately there is nothing left but bullets (which are still hot, and very very small.)

Answer 5

if the clock isn't destroyed by making use of the explosion then the capability grid that they run on truthfully substitute into. i think of you're refering to the clocks got here upon close to the area of the two atomic atacks on Japan. i've got considered photographs that reference the clocks scuffling with. Mechanical clocks could have been outdated and their springs very fragile As for electric powered clocks, the atomic blast places off a extensive electromagnetic pulse which disrupts electronics. additionally the capability flowers that run those cities have been destroyed. desire that explains it somewhat.

Answer 6

The high energy particles eventually loose enough heat through friction that they no longer have enough force to drive apart another atom.

Answer 7

atomic explosion is unstable proccess it cannot be stop but the rate of reaction can be decreased by sticks of cadmium

Answer 8

Just like a firecracker. It uses up it's fuel.
