chain reactions

listen to the pronunciation of chain reactions
İngilizce - İngilizce
plural form of chain reaction
chain reaction
A series of events, each one causing the next

The bombs all exploded in a chain reaction.

chain reaction
A nuclear reaction in which particles produced by the fission of one atom trigger fissions of other atoms

The Manhattan Project produced the first recorded controlled chain reaction.

chain reaction
a self-sustaining nuclear reaction; a series of nuclear fissions in which neutrons released by splitting one atom leads to the splitting of others
chain reaction
A chain reaction is a series of chemical changes, each of which causes the next
chain reaction
series of reactions in which each is directly caused by the one before it
chain reaction
The process by which the fission of a nucleus releases neutrons, causing other nuclei to undergo fission in turn Both the atomic bomb and the nuclear reactor use a chain reaction to generate energy
chain reaction
A reaction in which one of the agents necessary to the reaction is itself produced by the reaction, thus causing like reactions
chain reaction
From a 1/4 Tag formation only (at A1) Very Centers and the directly-facing Outside dancers Pass Thru as the End of the Center Line Counter Rotate 1/4 [walk forward in an arc, changing facing direction by 90°, 1/4 of a Circle around the outside of the set]; Centers of each side Hinge; Center 4 Star 1/4 as Outsides Trade; Those who meet Cast Off 3/4 as Others move up (Phantom Hourglass Circulate) A 1/4 Tag formation ends in Parallel Waves
chain reaction
A reaction that initiates its own repetition In a fission reaction, free neutrons are produced which fly off and strike other nuclei, causing them to split and send off yet more free neutrons The fission will continue as long as there are enough free neutrons carrying the right amount of energy
chain reaction
a self-sustaining fission process caused by the production of neutrons that proceed to split other nuclei
chain reaction
repeated fission caused when the neutrons released in fission bombard other atoms
chain reaction
A reaction that stimulates its own repetition, in particular one, where the neutrons originating from nuclear fission cause series of fission reactions
chain reaction
Lengthening of the main chain (backbone) of polymer molecules by end-to-end attachment
chain reaction
A large number of nuclear fissions, taking place within a certain mass of a fissionable isotope, that release a great quantity of energy in a short time
chain reaction
When a fissionable nucleus is split by a neutron it releases energy and one or more neutrons These neutrons split other fissionable nuclei, releasing more energy and more neutrons, making the reaction self-sustaining
chain reaction
A reaction that stimulates its own repetition, in particular where the neutrons originating from nuclear fission cause an ongoing series of fission reactions
chain reaction
A process in which one nuclear transformation sets up conditions for similar nuclear transformation in another atom Thus, when fission occurs in uranium atoms, neutrons are released, which in turn produce fission in other uranium atoms
chain reaction
a series of chemical reactions in which the product of one is a reactant in the next a self-sustaining nuclear reaction; a series of nuclear fissions in which neutrons released by splitting one atom leads to the splitting of others
chain reaction
a reaction which, once started, continues through its own action; the splitting of uranium atoms releases neutrons that, in turn, continue the process causing other uranium atoms to split
chain reaction
The continuing process of nuclear fissioning in which the neutrons released from a fission trigger at least one other nuclear fission In a nuclear weapon, an extremely rapid, multiplying chain reaction causes the explosive release of energy In a reactor, the pace of the chain reaction is controlled to produce heat (in a power reactor) or large quantities of neutrons (in a research or production reactor)
chain reaction
A reaction in which one of the starting materials is regenerated in the last step of the reaction
chain reaction
A process in which some of the neutrons released in one fission event cause other fission events that in turn release neutrons
chain reaction
A chain of events described by W Edwards Deming: improve quality, decrease costs, improve productivity, increase market with better quality and lower price, stay in business, provide jobs and provide more jobs
chain reaction
a self-sustaining reaction in which the products of one reaction event stimulate further reaction events
chain reaction
(nuclear) a self-sustaining fission process caused by the production of neutrons that proceed to split other nuclei (21 6)
chain reaction
A self-sustaining reaction in which one reaction event stimulates one or more addi­tional reaction events to keep the process going
chain reaction
A reaction in which the material or energy that starts the reaction is also one of the products and can cause similar reactions
chain reaction
(also Nuclear chain reaction) 1 A reaction that stimulates its own repetition 2 For example, nuclear reaction occurs when neutrons released from a split atom such as a uranium-235 (U235) nucleus go on to fission other nuclei This reaction produces additional neutrons that cause more fissions, which release still more neutrons to cause even more fissions, which release even more neutrons, and so on See Fission
chain reaction
A reaction which, once started, will produce a material or substance necessary to continue the reaction An example is nuclear fission Once a fission reaction is started, neutrons are released, which cause more nuclei to undergo fission, which release more neutrons, and so on
chain reaction
a series of chemical reactions in which the product of one is a reactant in the next
chain reaction
A chain reaction is a series of events, each of which causes the next. The powder immediately ignited and set off a chain reaction of explosions. Process yielding products that initiate further processes of the same kind. Nuclear chain reactions are a series of nuclear fissions initiated by neutrons produced in a preceding fission. A critical mass, large enough to allow more than one fission-produced neutron to be captured, is necessary for the chain reaction to be self-sustaining. Uncontrolled chain reactions, as in an atomic bomb, occur when large numbers of neutrons are present and the reactions multiply very quickly. Nuclear reactors control their reactions through the careful distribution of the fissionable material and insertion of neutron-absorbing materials
chain reaction
A self-sustaining reaction in which one reaction event stimulates one or more additional reaction events to keep the process going
