"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.
What else can I help you with?
Is nuclear chain reaction is called fusion?
No, a nuclear chain reaction refers to a self-sustaining series of nuclear fissions where the neutrons released in one reaction cause further fissions. Fusion, on the other hand, is the process of combining two light atomic nuclei to form a heavier nucleus, releasing large amounts of energy in the process.
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.
If a protostar doesn't undergo a nuclear fusion what will it turn into?
If a protostar does not undergo nuclear fusion, it will not become a star. Instead, it will either become a brown dwarf, which is a failed star that lacks the mass to sustain nuclear fusion, or it will simply cool down into a cold, dense object known as a sub-stellar object.
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 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).
What is the difference between cold fusion and what nuclear power plants do to create energy?
Cold fusion is a theoretical nuclear reaction that supposedly occurs at room temperature, while nuclear power plants use controlled nuclear fission reactions to generate heat and produce electricity. Cold fusion has not been reliably demonstrated, while nuclear power plants worldwide successfully use fission to generate a significant portion of electricity.
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!,
Is nuclear chain reaction is called fusion?
No, a nuclear chain reaction refers to a self-sustaining series of nuclear fissions where the neutrons released in one reaction cause further fissions. Fusion, on the other hand, is the process of combining two light atomic nuclei to form a heavier nucleus, releasing large amounts of energy in the process.
What is the formula for cold fusion?
Cold fusion is a type of nuclear reaction that occurs at or near room temperature, leading to significant energy production. The specific formula for cold fusion is not well understood or documented, as the process is still a subject of ongoing research and debate in the scientific community.
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
If a protostar doesn't undergo a nuclear fusion what will it turn into?

What is the cold fusion?
"Cold fusion" refers to fusion at (or near) room temperature, rather than the millions of degrees that are normally required. This has not been achieved so far - at least, not to any significant degree.
