Why does uranium not yield energy when fused with something else?

Melting of metals is a process with heat absorbtion, not with heat releasing; and the nuclear forces cannot be released by melting.

Nutrients that do not yield energy include?
Minerals and water
How much mechanical energy is in a nuclear bomb?
That depends on the yield.
Is a neutron bomb the most dangerous nuclear weapon?
no, yield is rather low because tungsten is used for fusion tamper instead of Uranium-238, so the fusion neutrons can escape instead of being consumed fissioning Uranium-238.
Energy yield of five grams of sugar?
Sugar is a pure carbohydrate. As such, one gram of sugar provides the equivalent of 4 kcalories of energy. Knowing this information we can conslude that five grams of sugar would yield 20 kcalories.
How does the neutron bomb work?
A neutron bomb is a type of hydrogen bomb. It actually was a development that came from the late 1950s work by the US to make "clean hydrogen bombs" that produced very little fallout. In a conventional hydrogen bomb the tamper (device to contain the nuclear reaction as long as possible to get as much energy from it as possible) is usually made with depleted uranium because of its high density and low cost. While depleted uranium will not support a neutron chain reaction it will fission when hit by the high energy neutrons produced by the fusion reaction of the hydrogen bomb. This depleted uranium fast fission can produce up to 90% of the total yield in some hydrogen bomb designs, as well as a proportional amount of the fallout. In a "clean hydrogen bomb" the tamper is instead made of some other very dense metal that unlike uranium will not fission when hit by high energy neutrons. Lead and tungsten have been used. However the explosive yield of a "clean hydrogen bomb" will be lower than a similar conventional hydrogen bomb because there is no fission in the tamper. But as these materials do not consume the high energy neutrons, they escape from "clean hydrogen bombs". It was observed that these neutrons easily pass through tank armor and building walls, killing those inside while the lower yield produces less blast and fire damage. Thus was born the idea of the neutron bomb.
Which radioactive isotope would have the highest fissial energy yield?
Uranium 64
Why does uranium shine when exposed to bright light?
The electrons when switch to next higher orbit they need energy to do it they do it by using energy of photons when the photons have equal energy to that required by electron theY absorb it,similarly when the are spelled out the yield out of uranium then they are accelerated to such speed that they emit their energy in showing a spectrum.
Why does iron not yield energy if fused with something else?
Because iron has very little binding energy, to get it to fuse you must add binding energy. This takes a supernova explosion or a powerful particle accelerator. Elements lighter than iron have excess binding energy that can be releases by fusion, but not iron (or any heavier element).
Do nuclear engineers make bombs?
It can and it is Although U-238 is not very radioactive -- it's sometimes called depleted Uranium -- it is used as a "tamper" in the core of nuclear warhead. Its use as a tamper greatly increases the yield energy of the device. Wikipedia has a pretty good article to check out. Uranium 238 is not fissionable with thermal neutrons; uranium 238 cannot be used in bombs as fissionable, explosive material.However as the final stage tamper of a hydrogen bomb the high energy fusion neutrons will fission Uranium-238, possibly generating 90% of the yield and a corresponding amount of the fallout of such bombs.
Does vitamins yield energy?
yes
What type of nuclear energy do hydrogen bombs produce?
Fusion. However in standard fusion bombs about 90% of the yield comes from fission of Uranium-238 in the fusion tamper and radiation channel guide from fast 15MeV fusion neutrons.
Why are nuclear bombs called 'dirty' bombs?
Fusion (thermonuclear) bombs can be classified into 'dirty' and 'clean' bombs, depending on the material used for their fusion stage(s) tamper. Normally depleted uranium is used, this produces a very high yield 'dirty' bomb as the uranium fissions providing as much as 90% of the yield and large amounts of fallout. If you are willing to sacrifice most of the weapon's potential yield (but the yield is still very high), you can replace the fusion stage(s) tamper with non-fissionable metals (e.g. lead, tungsten, iron) and get what is called a 'clean' bomb that in some cases produces 5% or less of the fallout of similar yield bombs with uranium tampers. There are also bombs called 'salted' bombs where selected elements are added to the uranium tamper to make the fallout worse at a minor loss in yield depending on how much of these elements are added. Sometimes these are referred to as 'dirty' fusion bombs, when the standard uranium tamper bomb is referred to as a 'conventional' fusion bomb.
What is the energy yield for glycolysis?
Two pyruvates.
What makes a H bomb more destructive than an A bomb?
it is a 2 (or more) stage device, the first stage is an A bomb while the remaining stage(s) contain fusion fuel. typically lithium deuteride. the amount of fission fuel (uranium or plutonium) that can be put in an A bomb is inherently limited. if you put too much in the bomb it will spontaneously begin to fission (possibly even during assembly or storage, definitely long before use and delivery to a target is possible) causing the bomb to heat up, melt, and produce a low yield fizzle explosion; producing mostly contamination not damage. it has been computed that the limit to the yield of an A bomb is about 1 megaton, the highest yield A bomb ever tested had a yield of 500 kilotons. the amount of fusion fuel that can be put in an H bomb has no such limit, fusion cannot begin spontaneously. also the yield can be raised by using as many stages as you want. also the fusion reaction produces many very high energy neutrons, which are capable of fissioning depleted uranium (which is not fissionable under ordinary conditions), if the outer casing/tamper of an H bomb is made of depleted uranium it is possible to raise the yield of the H bomb by up to a factor of 10. the first H bomb tested had a yield of 10 megatons. the highest yield H bomb tested had a yield of just over 50 megatons, but had it used the uranium casing/tamper it was designed for the yield was predicted to be 100 megatons.
What is the energy molecule that breaks apart in the muscle cell to yield energy?
adenosine triphosphate
What nutrients supply your body energy?
Carbohydrates, fats and proteins yield the energy the body needs to fuel its various activities. Vitamins, minerals and water do NOT yield energy, but perform other tasks such as maintenance and repair.
