In stars it starts due to the great pressure at the star's center, which compresses the hydrogen and raises temperature to a condition where fusion commences. On Earth in man made equipment such as tokamaks, the pressure is much lower and the temperature has to be raised to hundreds of millions of degC to start fusion in a plasma of deuterium and tritium

What is a sentence for thermonuclear?
The thermonuclear reaction in the sun produces vast amounts of energy through the fusion of hydrogen atoms.
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 a fission reaction is neccasary for fusion reaction?
It isn't, in general. Thermonuclear bombs use a fission bomb to generate the heat and pressure required to start the fusion process, but there are other ways of doing it (stars do so by gravity, for instance).
What is the difference between an atomic bomb and a thermonuclear bomb?
They are both general terms. The term "atomic bomb" can mean any nuclear weapon, either a fission weapon or a fusion weapon (the so-called hydrogen bomb). The term thermonuclear bomb is also used in general, but it usually excludes the fusion bombs. It should be noted, however, that it takes a fission bomb to generate the heat necessary to "set off" a fusion reaction and make a fusion bomb work.
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 type of reaction occurs when a thermonuclear bomb explodes?
A fusion reaction.
What is thermonuclear fusion takes place?
It simply means that thermonuclear fusion happens.
The suns heat is produced by?
thermonuclear fusion and hydrogen becoming helium... :)

What chemical reaction produces the sun and energy?
These are not chemical reactions but thermonuclear reactions.
What type of thermonuclear reaction occurs in the sun which generates a tremendous amount of heat energy?
The main thermonuclear reaction in the sun is the fusion of hydrogen nuclei (protons) into helium nuclei. This process, known as nuclear fusion, releases a tremendous amount of heat energy and is responsible for powering the sun and providing light and warmth to the Earth.
What is a fusion reaction also known as?
Since they do not exist yet I do not believe they have any other names. Fusion does exist in nature so a sun or star could be considered a fusion reactor.

What element is created during thermonuclear reactions?
At the core of our sun, Helium is created by the thermonuclear fusion of Hydrogen.
What nuclear energy is the sun powered by?
thermonuclear fusion
What is thermonuclear?
Nuclear reactions initiated by, and/or depending on heat. As a generic term, thermonuclear is an adjective describing atomic processes involving heat. This definition is necessarily vague, so in practical terms, the word thermonuclear applies specifically to weapons and power generation. Thermonuclear weapons use the heat generated in an initial nuclear fission reaction to cause a chain reaction of further fission and fusion reactions, releasing energy. Thermonuclear fusion is the proposed method for achieving nuclear fusion for power generation. The very high temperature, combined with some form of containment, causes the atomic nuclei to fuse together, releasing energy. Nuclear fusion requires a minimum level of kinetic energy in each collision before the electrostatic repulsion of nuclei is overcome, permitting them to fuse.
