Calculate the energy release for the complete fusion of one mole of deuterium H + H = He + energy i can't do the signs for mass number etc. it quotes the Avogadro constant so that's a clue but help! http://billnye.ytmnd.com

So here it is: What is the energy released when one mole of deterium(?) undergoes complete fusion? Oh, here's the equation: H + H = He i don't know how to post but its 2,1 for both hydrogen isotopes and then 4,2 for the helium duh i know but i don't want confusion. cheers ro><ors...

Could it be possible to one day create fusion bombs that are "clean"(not create radioactive isotopes and other nasty stuff that lingers for years)? The only thing it'd do is create thermal energy and the bast when it goes off?

The first step in the nuke reaction of the sun is p-p reaction p + p = d + e+ + neutrino My question is, if the two protons are coming say from the -x and +x direction, what is the final direction of the products formed in the xyz axis.

Could anyone give me a few examples of endothermic fusion reactions between elements solid at room temperature?

Why can't fusion be accomplished using high energy density electric fields?

In astronomy class i was told that a grouping of hydrogen must reach 10,000,000K for fusion to occur. Without a sun being a certain size, gravity could never be great enough to generate such high temperatures-brown dwarf. So, could you artificially accelerate gravity (as in future plans for...

I had a lab about tin's heat of fusion. I need to know tin' specific heat near fusion point. Can anybody advice any useful resourse? I have two books, in which are opposite data. I suppose that liquid tin must have higher heat capacity as solid ("liquid" molecules have more "freedom"). Help me...

Can anyone here tell me how long it will be (roughly) until hydrogen fusion power stations are producing energy at economic rates? it can't be far off can it? thx

According to this release, bubble fusion (i.e. using ultrasonic waves to induce the rapid collapse of bubbles causing the atoms at the center to fuse), has been convincingly demonstrated in the laboratory. http://www.rpi.edu/web/News/press_releases/2004/lahey.htm#cool At least two movies...

Bubble Fusion - verified?! http://www.rpi.edu/web/News/press_releases/2004/lahey.htm#cool: could this finally be it?

Hello I just recently finshed physics honors on a high school level, but my class because of bad weather, and a tight schedule was unable to go over anything having to deal with automic physics. Could anybody direct me to understanding fussion, and the theories that have been brought up about...

I found this. Is it cranks or for real? http://www.progressiveengineer.com/PEWebBackissues2002/PEWeb%2028%20Jul%2002-2/28editor.htm http://www.focusfusion.org/

Anyone trying this experiment? Put a solid cylindrical electrode (anode/cathode) inside a hollow cylindrical or tightly coiled electrode (cathode/ anode) so that there is only a minimal ‘potential space’ between the two electrodes, and immerse them in a suitable electrolyte solution. The...

topic pretty much explains it. why is it that fusion releases more energy than fission?

Hey. I am doing a lab experiment in school to find the molar enthalpy of fusion of water. Ice and water are mixed in a calorimeter and the temperatures are recorded. Here are my results. Mass of ice cube: 6.61g. Mass of water: 100g. Initial ice temperature: 0 degrees celsius. Initial...

Is helium a better alternative then the current proposed fuels for fusion reactors? http://www.space.com/scienceastronomy/helium3_000630.html http://www.asi.org/adb/02/09/he3-intro.html

Is it know why the Earth's core, and indeed the cores of other planets, are "hot" while some are cold? Is it possible that fusion or fission processes are taking place there ?

Dear Folks: I have posted this Question all over the web, physics forums, science magazines, academics in plasma physics and condensed matter, I have received little response. Can you be of assistance? I thought this might interest you. I have been researching Hydrogen-boron...

I am very ignorant on this subject and was just wondering a few things. What exactly is it (how do they do it), I am having trouble finding information on it. Why can't it be recreated, or was it really done at all? Also I was wondering what resources it uses to create the energy. Thanks

Hi there. I'm doing an critical essay (~ 5k words) on Fusion Reactors and whether they will be the energy source of the next millenium. I'm struggling to get to grips with the main scientific problems and proposed solutions of fusion right now. I can find many books on the history of...

How far is research really gone? Is there any major breakthrough on its way? Are the first prototypes ready yet? I'm making a project work on this for school, and I find it hard to find sufficient information in books and likes about this, since clearly, books from the beginning of the last...

could anyone explian how do we get energy from the nuclear fusion and fission thx isnt that fission requires bindling energy which use up energy

fusion in frame...? hi guys! i am new in this field, so i hope that "mature" people can show me the way. thanks in advance! with fusion in frame does it mean that the nucleotide sequences of both DNA fragments i fuse with each other have to act as independent triplet unit? in this way we...

you decide the headline is something about Back from the Dead http://www.spectrum.ieee.org/WEBONLY/resource/sep04/0904nfus.html

I've heard that the weak interaction actually governs fusion between hydrogen especially in the sun, how does this actually works?

Why do we need much more energy for fusion than fission? PS: I apologize for my bad English,

how about cold fusion? I know it's got avid supporters as well as those who say it's total B.S. last I heard, it had something to do with the way Palladium acts in hard water... I'm going to go look some of that up. I want input! anyway, i hear it's possible. edit: thanks...didn't even notice...

I'm a noob in this lol, but a thought just cross my mind. If in nuclear fusion, we require high temperature to overcome the EM repulsion of nuclei, is it possible to bypass this and simply make use of the nuclear force, or color interaction which holds the nucleus together. Is it possible to...

Please see the attached Word file.

Over the past year, I've evaluated my own research and observations and matched them up with some statements from a pair of friends. One worked on a nuclear sub, and the other worked on an aircraft carrier. Both worked in the nuclear engine rooms. As I've been refining the concept of...

Well Dr. Kaku?

Hi, and thanks for looking I'm doing a heat of fusion lab for school and I'm having trouble trying to find the equations that would solve the following: Q (heat) released by liquid cooling down Q (heat) absorbed by melted ice warming up Q (heat) absorbed by ice while melting /\ (delta...

I'm somewhat stumped on this question from my son who's in Grade 10 Physics. Question: You put 100g of ice into a glass of 2400g of water at 10C. What is the final temperature of the water? Hmmm. Sounds simple, BUT, I know, Q= m(delta)H(fus) where (delta)H(fus)= 333J/g for...

Could anybody give me any suggestions, as to how i could convert 1 mince pie into around about 70 000J of energy, which could be used to power an engine of some sort ? I ask this, as I am creating a santa statistic :P not very origonal anymore i grant you, however, i was hoping to create a...

why they don't use good ol' accelerator smashing? bring two deutrons to couple of KeV (witch is not a particular problem) and collide them in some vacuum chamber. same charge repulsive force will be couple of magnitudes smaller than force on paticle under acceleration, so where's the problem?

Has controlled nuclear fusion been achieved?If not,is it a possibility in the foreseeable future?

A protostar will begin gravitational collapse only if the total gravitational potential energy exceeds twice the thermal energy. In other words, a gas has to be sufficiently cool and sufficiently dense to collapse. Also, as the protostar collapses about half of the gravitational PE is converted...

can someone explain to me this term? i know that's it is concenered to commutivity (or the lack of it).

[SOLVED] Iron Fusion In Stars If iron is said to be the last stage of fusion in stars, how is it that heavier elements are found on earth, where there seems to be less likely a chance for such fusion to occur? Where do these elements come from? Moreover, the half-life of a heavy element on...

[SOLVED] &quot;cold fusion realized&quot; I overheard a discussion the other day and it correlated with something I saw on TV years ago. It was about "cold fusion realized." It made a lot of sense and now I am fascinated. What I saw on TV revealed a science experiment where the teacher...

Can we consruct a centrifuge to accelerate ions and coerce them to fuse into heavier elements? It would have to be a sweeping electric field, because any moving parts would disintegrate from the great velocity they'd invariably have to have. Think fusion could be achieved this way?

Do you think that cold fusion is posible? Also, if it is what would some of the implications of this be, how would it change our world?

There is the hydrogen bomb and there is the nuclear weapon that uses plutonium. As far as I know the atomic structure of hydrogen versus plutonium are at the opposite ends of the chemical chart spectrum. Hydrogen having the least atomic weight of all elements and plutonium having a very high...
