What is the difference between hot nuclear fusion and cold nuclear fusion?
"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.
What is Coal Fusion?
I think you mean "Cold Fusion" It is the (currently) hypothetical nuclear fusion reaction which happens at ambient temperatures?
Cold fusion powered Submarines for all?
there is no such thing as cold fusion. although when it gets invented you can be sure that subs will be one of the first to get it. all American subs are powered by nuclear fission. the nuclear reactions heat water which is pumped into a device called a steam generator. the steam generator makes... steam! the steam powers the turbines that make electricity and propel the boat.
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 are the social technological and economical costs of nuclear fusion?
These have not been determined because a nuclear fusion plant has not been built. Most attempts at nuclear fusion provide a great deal of energy to start the fusion process, so much that ordinary containment vessels would vaporize. In order to deal with this, it is necessary to contain the reaction with such a thing as a set of magnetic fields or with laser beams. Reactions have been made to happen, but there is a long way to go to get one that produces more energy than it consumes and can operate continuously. Another attempt, called cold fusion, has been largely regarded as an impossibility. So there are technological problems and economic problems, and there is a certain amount of money being spent on research, but the actual costs will not be known for some time.
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.
Would cold fusion be enough energy to create a warp field?
neither cold fusion nor warp fields exist.
Why can't cold nuclear fusion work?
cant repeat the same process twice!,
What were martin fleischmann and stanly pons trying to prove?
Martin Fleischmann and Stanley Pons were trying to demonstrate a process called cold fusion, which involved creating nuclear reactions at room temperature. They believed that this process could produce excess energy and potentially revolutionize the energy industry. However, their claims were met with skepticism and controversy within the scientific community.
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.
