A thermonuclear explosion occurs when an element, usually hydrogen or helium, is heated to the point that the nuclei of atoms become unstable. The result is fusion, when atoms combine to form the atoms of heavier elements, giving off enormous amounts of energy, which sustains the heat that resulted in fusion. In a "hydrogen" bomb, the initial energy to achieve the required temperature is provided by a small atomic (fission) bomb. The thermonuclear energy is dissipated in an enormous explosion. This process occurs naturally in the sun and stars.

Why are the high temperatures produced by the explosion of a fission bomb necessary to initiate fusion in a thermonuclear device?

On the order of 10 million K.


Which is hotter the explosion of a thermonuclear bomb or the core of the sun and explain why?

The temperatures are similar within about an order of magnitude, but the core of the sun is hotter. The thermonuclear bomb is at the temperature of DT fusion, the lowest temperature at which fusion can occur. The sun, in addition to fusing DT, is fusing HH, HD, DD, DHe-3, TT, He-3He-3, all of which ignite at various temperatures higher than DT.


Why are the high temptress produced by the explosion of a fission bomb necessary fusion in a thermonuclear device?

The high temperatures produced by the explosion of a fission bomb are necessary for initiating the fusion reaction in a thermonuclear device because fusion reactions require extremely high temperatures and pressures to overcome the repulsive forces between positively charged nuclei. The fission explosion provides the energy needed to achieve these conditions, thereby allowing the fusion reaction to take place.

Why is potassium not used instead of hydrogen in bombs?

Potassium is a salt, a crystalline substance and is not radioactive sufficiently enough to achieve the level of critical mass necessary to energize such an explosive reaction. A hydrogen bomb is a two-stage nuclear device that actually uses a lower-level nuclear reaction to energize a higher-level thermonuclear explosion. That higher-level thermonuclear explosion is what you call a hydrogen bomb. Tom Clancy gave a brilliant explosion of such a device in his book "The Sum of All Fears".


What does thermonuclear dynamics mean?

Thermonuclear dynamics is the study of the forces and motion involved in thermonuclear reactions.


When was On Thermonuclear War created?

On Thermonuclear War was created in 1960.


What is a sentence for thermonuclear?

The thermonuclear reaction in the sun produces vast amounts of energy through the fusion of hydrogen atoms.


What is the difference between nuclear and thermonuclear weapons?

Nuclear weapons' yield is derived primarily from fission. Thermonuclear weapon's yield is derived mainly from fusion. Thermonuclear weapons are multistage weapons -- x-rays from a nuclear primary trigger are used to trigger ablation in the pusher of the secondary to compress it, which is responsible for the fusion reaction.


What is thermonuclear fusion takes place?

How do stars other elements?

for making elements from helium to nickel and iron, thermonuclear fusionfor making elements past nickel and iron a supernova explosion is needed to force nuclei to fuse more, this destroys the star


The suns heat is produced by?

thermonuclear fusion and hydrogen becoming helium... :)
