Can atom annihilate by 58 nuclear megatons to nothing?

[hellwing]

well, it is a lot of energy so yes, if someone is close to a 100megaton nuclear bomb detonating, they will be fataly ionized. ions are not the same as antimatter though.

 

THANK YOU!!

I understand.

[Kyrisch]

It almost sounds as if he's PLANNING on blowing someone up and making it as 'paintfull' as possible.

[insane_alien]

ah the old nuke in a paintcan explosion.

[hellwing]

@insane_alien

if there is an megaton explosion is it also destroy the oxygen while making an explosion?

lol the megaton nuclear is heading on you.

hehe.

well, a nuclear bomb will ionize just about everything close to the bomb, thiswill be plainly obvious as everything within the fireball is ionized(although it is possible for a large chunk of solid matter to partially survive ionization if it takes longer than the lifetime of the fireball to ionize all the way to the center.

 

so, oxygen molecules will be ripped appart and the oxygen atoms themselves will be ionized. its not really destroyed though.

that means everything that close to the bomb would ionized not only just oxygen atoms all atoms turn to ions?

[insane_alien]

yes, nuclear bombs are very boring in that regard while the effect certainly looks impressive, when you break it down nothing extraordinary is happening, well, outside the source of the energy anyway.

thank you sir,ready to lunch..

 

the electrons is surrounding the nucleus of atoms,what will happen to this electron while the the 100 megatons of nuclear exploding? did this also turn to ions?

[Kyrisch]

I don't think you understand what ions are. Ions are fractured atoms -- atoms with a net charge (meaning they either have more or fewer electrons than normal). The electrons and protons themselves aren't ionised, the atoms are. 'Ionisation' describes the behaviour of electrons with respect to the atoms.

so you mean if atoms caught by 100 megaton means you fractured the atoms or brake into a small particles?it is also called ionized?

[Cap'n Refsmmat]

You don't really "break" the atoms. You essentially either steal an electron (or two) from the atom or give it some extra electrons. That's how you get an ion.

[YT2095]

there are atom transformations however, whereby an element will be changed into another element or turned into an isotope of the original element, Neutrons are responsible for this.

 

IIRC the metal Nickel is one such element to be avoided if it`s been exposed to the radiation from a nuke.

break and fructure are the same,right?

about antimatter and matter,what happened to electron if matter + antimatter anhihilated each other,turn to photons?

is there a site that has some images about this?

Atoms are actually made up of smaller parts. There is the Nucleus made up of Protons and Neutrons. Then there are the Electrons that exist in a cloud that surrounds the nucleus.

 

As the electrons are (relatively) loosely bound into the atom, it is easy to strip them away from the atom. This process is called ionisation.

 

An easy way to do this is by directing photons (light) of the right frequency at them. Also, if enough photons hit the electrons in succession, they will also get enough energy to be knocked away form the atom. Another way is to heat the atoms up. This heat can cause the electrons to escape the atom and hence ionise it.

 

about antimatter and matter,what happened to electron if matter + antimatter anhihilated each other,turn to photons?

There are just as many forms of antimatter as there are normal matter. Anti Matter is a type of matter with an opposite charge. So you can have an antimatter electron called a positron that is the same as an electron but has a positive charge instead of a negative charge.

 

When matter and antimatter of the same particle type collide (and because they are opposite charges they naturally attract each other), they annihilate into photons. There is nothing left of both particles except for these photons.

 

Of course any particles not involved in the annihilation will still exists, and the photons created in the annihilation can interact with them, just and any other photons would.

[hellwing]

thank you @Edtharan.

 

is there someone knows here on how to measure the heat or temperature of 1 megaton nuclear?

[YT2095]

spectral analysis of the light given off is a good indication of heat.

[hellwing]

that's hard.

[YT2095]

but it beats the alternative

[insane_alien]

nah, just point your spectrometer at the fireball.

 

although, that will only give you the surface temperature. i think. the internal temperature would need to be calculated from that.

 

a megaton nuclear bomb will produce temperatures hotter than the suns core in general though.

Can atom annihilate by 58 nuclear megatons to nothing?

The term annihilate as it is used in physics refers to the process that occurs when a subatomic particle collides with its respective antiparticle. The term megaton is used to refer to the energy released in an explosion. E.g. 1 megaton is the amount of energy released when a process releases the same amount of energy released when 1million tons of TNT is detonated. So I guess you could say that the explosive energy released when 1 million tons of TNT is detonated is 1 megaton.

 

When two particles annihilate matter doesn't just disappear. It changes from particles with non-zero proper mass to photons, each of which has zero proper mass.

[hellwing]

thank you also pete.

if i have a 5 kilograms of matter plus 1 kilo of antimatter what will happen to 5 kg of matter?

do you think it would left 4 kg from 5kg?

[insane_alien]

you would be left with 4kg of matter and 2kg worth of photons.

[hellwing]

you would be left with 4kg of matter and 2kg worth of photons.

 

we know the 1 kilo annihilated but i think the 4 kg should also caught from the explosion because it is a part of 5 kg,right?

now what happened to 4 kg is it also destroyed but not annihilated?

[insane_alien]

yeah, the 4kilos left over would likely be vaporised. but it would still exist as matter.

[hellwing]

and what do you mean by 2 KG worth of photons?
