What is the difference between hot nuclear fusion and cold nuclear fusion?

∙ 12y ago
"Hot" nuclear fusion (this is not the term normally used) is exactly what the name implies, the materials are heated, which provides them with enough energy to overcome the normal repulsion of protons.
Cold nuclear fusion requires no heating and has not yet been proved, although dozens of Physicists and Electro-Chemists have claimed to have created cold fusion. Cold Fusion relies on other forces, such as pressure, to overcome the electrostatic force of repulsion.

Is nuclear chain reaction is called fusion?
The idea of nuclear fusion occurring at room temperature is called cold fusion.
Is sustained nuclear fusion possible?
It hasn't been achieved yet, and it seems doubtful that it is possible. You may want to read the Wikipedia article on cold fusion to get a more detailed overview. To summarize it: the muon-catalyzed kind definitely is possible and is routinely done by researchers in the field - the problem is that it requires more energy to generate the muons than you can get out of the fusion. The Fleischmann and Pons kind appears to have been poor laboratory technique (I'm being charitable here, and not suggesting that it was deliberate fraud).
Does nuclear fusion occur at a low temperature?
No, normally it occurs at temperatures of millions of degrees. It does occur at room temperature, but not in significant amount; any possible practical use of "cold fusion" is, so far, speculation.
Which kind of nuclear reaction is the source of the sun's energy?
The Sun, like other stars similar to it, is sustained by a Nuclear Fusion Reaction at its core. Unlike Nuclear Power here on Earth, which is created by the process of splitting atoms (Nuclear Fission) Fusion creates energy by fusing atoms together. This has proven a difficult objective to achieve here on Earth - though it occurs naturally in stars, on Earth the problem is containment, a problem that has as yet not found a viable solution. Though the extreme gravity of stars is what initiates a fusion reaction in them, it has been theorized recently that a fusion reaction at smaller levels with chemicals is possible. This is commonly referred to as "Cold Fusion" for the relatively low amount of energy it would produce in contrast to nuclear fusion. Though Cold Fusion has largely been discounted, it continues to be researched. Often the biggest scientific breakthroughs are made by those who do not always hold to conventional scientific beliefs. If we did, we would have never done things like go to the Moon, or broken the Sound Barrier. In the time before it happened, both were considered by mainstream science as "impossible" to achieve.
Is nuclear fusion more dangerous then nuclear fission?
We don't know much about fusion as it is still very experimental. It will not produce the dangerous fission products that fission does, but it may have other dangers unknown as yet. Nuclear fusion has more destructive potential than fission. Fusion is the principle powering the H-bomb developed in the Cold War. Just to put the power of a Fusion bomb in perspective, it is detonated by a fission bomb half the size of the one dropped on Japan. THAT'S JUST THE DETONATOR.
Is nuclear chain reaction is called fusion?
The idea of nuclear fusion occurring at room temperature is called cold fusion.
What is Coal Fusion?
I think you mean "Cold Fusion" It is the (currently) hypothetical nuclear fusion reaction which happens at ambient temperatures?
Why can't cold nuclear fusion work?
cant repeat the same process twice!,
Why wouldn't the human raise exist without fusion?
The sun runs on nuclear fusion. No sun and the Earth is just a cold dead rock.
Is Neptune a sun?
No, Neptune is a planet. Stars are hot, glowing with the heat from nuclear fusion in their core. Neptune is cold, and much too small to have fusion.
Why only in the sun's core does nuclear fusion occur?
The rest of the sun is too cold and too low pressure.
What has the author Tadahiko Mizuno written?
Tadahiko Mizuno has written: 'Nuclear transmutation' -- subject- s -: Cold fusion
Difference between cold souffl'e and bavarios?
Difference between cold souffl'e and bavarios?
What has the author Nate Hoffman written?
Nate Hoffman has written: 'A dialogue on chemically induced nuclear effects' -- subject(s): Cold fusion
Give one relevance of nuclear physics?
Nuclear physics is relevant to the average person in the way it affects energy use of humans. These advances include electricity, fission, nuclear power pants, and perhaps cold fusion in the future.
What is the difference between a cold and a bus driver?
The difference between a cold and a bus driver is a bus driver has a course to run and a cold has to run its course.
When was Cold Fusion - Doctor Who - created?
Cold Fusion - Doctor Who - was created in 1996.
