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
In a thermonuclear fusion reaction, the process begins when the high temperature and pressure inside a fusion reactor cause hydrogen nuclei (protons) to overcome their electrostatic repulsion and fuse together, forming helium and releasing a large amount of energy in the form of heat and light. This reaction typically starts once the conditions are optimal for sustaining a self-sustaining fusion reaction.

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?
A fission reaction is not necessary for a fusion reaction. Fission reactions involve breaking apart heavy atomic nuclei, which releases energy. Fusion reactions involve combining light atomic nuclei, also releasing energy, but under different conditions. One does not require the other to occur.
What is the difference between an atomic bomb and a thermonuclear bomb?
An atomic bomb relies on fission (splitting of atoms) to create an explosive chain reaction, while a thermonuclear bomb, also known as a hydrogen bomb, uses both fission and fusion (merging of atoms) to create a much more powerful explosion. Thermonuclear bombs are more destructive than atomic bombs.
What is the difference between nuclear and thermonuclear weapons?
Nuclear weapons rely on nuclear fission to release energy, while thermonuclear weapons (hydrogen bombs) use both nuclear fusion and fission reactions to generate a much more powerful explosion. Thermonuclear weapons are considered more destructive and have the capability to produce significantly larger explosions than traditional nuclear weapons.
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 is a sentence for thermonuclear?

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?
A fusion reaction is also known as a thermonuclear reaction because it occurs at extremely high temperatures similar to those found at the core of stars.
Why are the high temptress produced by the explosion of a fission bomb necessary fusion in a thermonuclear device?

What element is created during thermonuclear reactions?
At the core of our sun, Helium is created by the thermonuclear fusion of Hydrogen.
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.
What nuclear energy is the sun powered by?
thermonuclear fusion
