A nuclear chain reaction occurs when a nucleus undergoes fission, releasing energy and more neutrons. These neutrons can then collide with other nuclei, causing them to also undergo fission and release additional neutrons. This process continues in a chain reaction, leading to the release of large amounts of energy.

Why does an atomic bomb go off?
An atomic bomb goes off when a chain reaction of nuclear fission is triggered, causing a massive release of energy in the form of heat, light, and radiation. This chain reaction is initiated by compressing a critical mass of fissile material, such as uranium or plutonium, to a point where the atoms split and release more neutrons to continue the reaction.
How do nuclear bomb blow up?
A nuclear weapon specifically functions based off of different designs. Lets take the Hiroshima weapon for simplicity as this is the least complex design that is out there. The Hiroshima bomb called little boy is a simple gun type fission weapon. The weapon was designed using U-235. When the trigger on this weapon goes off, it sends a subcritical piece of Uranium down a cannon barrel to contact another piece of Uranium at the other end. The pieces meet at a certain speed causing a super critical state to be achieved. Once this occurs the nuclear chain occurs within the Uranium causing the massive release of energy that becomes the explosion. The actual function and numbers for the design of the weapon are classified; however, that is the simplified version of how the weapon detonates.
When was nuclear energy developed?
I think that goes back to Albert Einstein, though he only theorised about it, but was correct (E = mc2). To make it a practical process, I would nominate Enrico Fermi as the foremost scientist in the field, though also Robert Oppenheimer was principal in developing the A-bomb.
How does the law of conservation of energy apply to nuclear energy?
Before the reaction, the energy exists as potential energy, caused by the nuclear forces. After the reaction, the energy goes away as gamma rays for example, which may eventually be absorbed and get converted to heat.
What property of the fission reaction leads to the possibility of a chain reaction?
The fact that when a fission occurs, more than one neutron is released. Thus by careful design, one of these second generation neutrons can be captured by a further nucleus causing another fission, and so on. Up to about 2.5 neutrons per fission can be utilized. In a bomb, all of them are used, and the reactivity (approximately) doubles with each reaction. In a controlled reaction, such as in a reactor, the moderator and geometry are such that one neutron per fission goes on to create another fission, yielding a stable reactivity.
How does the sun goes on shining?
Due nuclear reaction on sun which are uncontrolled chain reaction with huge amount of energy
What is it called when a chemical reaction occurs and the temperature of the surroundings goes down?
This is an endothermic reaction.

What will happen if nuclear fission chain reaction goes on indefinitely?
It can and does in a reactor. Nothing special. However reactors usually require periodic refueling and maintenance, which may require short shutdowns or at least reduced operating power for these activities.
What would happen to a nuclear plant if the fission reaction goes critical or out of control?
There are emergency safety system that could be used to bring the nuclear plant again under control.
What energy source is used to create nuclear energy?
Nuclear energy arises in a fission reactor by the splitting of nuclei of uranium or plutonium, there is no need for any energy source to start the process. You just set the chain reaction going by assembling enough fissile material with a moderator in the right geometrical arrangement, and away it goes. Another answer: The energy source is the weak nuclear force, from the nucleus of the atom. In other words, nuclear energy IS the energy source.

Is transmission of HIV a chain reaction?
In that one person is infected by another, then infects a third person, who then goes on to infect another person, yes, HIV is a chain reaction. It is spread through human conctact and transmission of the virus through the blood and body fluids.
Does nuclear radiation go away?
No, it doesn't.Wrong, it does. There are 2 types of nuclear radiation: prompt & decay.Prompt nuclear radiation occurs for a period of time while the reaction that generates it is happening. Examples are the flash of neutrons, light, x-rays, etc. when a nuclear bomb explodes as well as the sustained neutron flux as a nuclear reactor is in operation. When the reaction stops, prompt nuclear radiation goes away.Decay nuclear radiation occurs as radioactive isotopes decay to different isotopes. As the decay happens (which is a probabilistic process) the radioactive isotope is consumed. This follows an exponential function with one half of the current amount of the radioactive isotope consumed in each period of time called a halflife. While there will always be a tiny residue of the original radioactive isotope, for practical purposes it is considered to be negligible after 5 halflives have passed. When 5 halflives of the radioactive isotope decaying have passed, decay nuclear radiation is considered to have gone away for practical purposes.
What is the difference between a controlled and uncontrolled reaction that has to do with nuclear stuff?
A controlled reaction is something done under restrictions and prohibitions, in the case of nuclear experimenting, it is as to not create a deadly weapon but to study that reaction and basically to split the atom without an explosion. When the neutron is flown at the atoms nucleus, it splits the atom, splitting the nuclei, which creates more nuclei which are also split which create more and so on. However, if this gets out of hand, and it goes to fast and the energy is released to quickly, it will be an uncontrolled reaction and this immense amount of energy will cause an atomic explosion. Basically the chain reaction needs to be controlled and slowed down. This will make it a controlled reaction. It can be controlled in several ways.
What is the song name that goes like chain chain?
chain chain by abba
Will Keha ever release Chain Reaction on iTunes?
According to Kesha's official website, "Chain Reaction" is about beginning to see the universe as a cyclical chain of connected events after meeting a guy in a club. The song was on her official MySpace (Keshaishot) in 2007, along with "Friday Night Fight," "Boots & Boys" and "Backstabber," when she was known to the world as K$ and was not a famous pop star. The song was featured in MTV's "The Hills." "Chain Reaction" still remains unreleased. Lyrics: Action Chain reaction-action Chain reaction-action I feel like I'm hallucinating Yeah you're tripping me out I can't control it's you I'm craving I can just tell you're down Come get me, let's get rowdy Boy you look so d*mn good on me Back to the wall On my silhouette When you walked right by Felt your breath on my neck And it felt so deep In a trance of a sleep Have I seen you before? Once in a dream Like a flashback, sneak attack, chain reaction At the first sight you just might be the right one You got something and again like a rerun Try but can't explain this chain reaction You hit me like a shot of whiskey You got me walking sideways Tunnel vision feeling frisky Want to get you stuck on replay I don't fall like this I must confess you cast a spell upon me Shadows of us in the room of sweat You took my hand to the back and the left And it felt so deep In a trance of a sleep Have I seen you before? Once in a dream Like a flashback, sneak attack, chain reaction At the first sight you just might be the right one You got something and again like a rerun Try but can't explain this chain reaction Ohhh ohoh, chain reaction Spin me around, all around Oh feels like a lifetime (I've been waiting) One domino goes down Then they all hit the ground (And not deliberating) It all happens for a reason right? Guess there's no need to fight it right? Cause one thing leads to another, Leads to another, leads to another Like a flashback, sneak attack, chain reaction At the first sight you just might be the right one You got something and again like a rerun Try but can't explain this chain reaction Chain reaction, this chain reaction Chain reaction, this chain reaction Chain reaction, this chain reaction Chain reaction, this chain reaction
