In detail what they mean when they say a body was “vaporized” during a nuke? What exactly happens to bones and everything and why?
In: Biology
Instant cremation, body turns to dust and the dust is scattered on the very strong winds so no trace is left of the body.
The calcium in your bones melts at 842°C, and boils at 1494 °C. The temperature of a nuclear fireball is on the order of 100,000,000 °C
If you shove enough energy into anything, it’ll eventually turn into a gas. Alternatively, if you only put in enough energy to liquify it or turn it to ash, but then hit it very hard, you get vapor.
A nuke isn’t a bomb in the sense of pressure and ripping things apart and shrapnel, it’s actually a flash of energy so intense that everything melts and then boils and turns into gas from just the light of it. [Like being so close to the sun](https://www.youtube.com/watch?app=desktop&v=Yt3JVgzOZzE).
Materials can only take some [6000 degrees](https://en.wikipedia.org/wiki/Melting_point) – tungsten, really hard metals. The temperature in the Sun and in a nuke flash is millions of degrees. Everything melts (solid to liquid), boils (liquid to gas) and becomes a gas, no material can withstand such temperatures.
Gone, reduced to atoms.
There is so much energy that every force holding the molecules together is overcome by the explosion. Only the strongest chemical bonds, like ionic bonds in salts may be able to survive.
