Why are high temperatures needed for fusion reactions to occur but not fission reactions to occur?
In fusion reactions, nuclei need to overcome the strong electromagnetic repulsion to merge and release energy, requiring high temperatures to achieve the necessary kinetic energy. In fission reactions, nuclei need to be bombarded by neutrons to induce a split, a process that can occur at lower temperatures.

Detonation of a fusion type hydrogen bomb is started by?
Detonation of a fusion hydrogen bomb is initiated by the primary fission bomb, which generates high temperatures and pressures needed to trigger fusion reactions in the hydrogen isotopes. The fission bomb compresses and heats the fusion fuel to the point where nuclear fusion reactions can occur, releasing vastly more energy than the fission reaction alone.
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.
What is used as a trigger in a hydrogen bomb?
A traditional nuclear fission bomb is used as a trigger in a hydrogen bomb. The explosion from the fission bomb generates the high temperatures and pressures needed to initiate the fusion reaction in the hydrogen bomb.
How is fusion used in a hydrogen bomb?
a hydrogen bomb is a fusion bomb. even though in standard types of hydrogen bombs 90% of the yield is fission, caused by uranium-238 fission by 15 MeV neutrons from the fusion reaction.
What is fusion and fission bomb?
Fission reaction gets its energy from breaking up large nuclei (e.g. uranium, plutonium) into smaller ones.Fusion reaction gets its energy from combining small nuclei (hydrogen isotopes) together to make bigger ones (helium).Modern nuclear weapons are rarely pure fission or fusion, but are typically some mixture of them in a unique arrangement to get desired effects, in a desired package size, at an affordable production cost.

Do fusion reactions provide nuclear power?
No, a fission reaction is not necessary to trigger a fusion reaction, but for us on earth, it is. In the field of nuclear weapons, a fission bomb is needed to create the heat necessary to set off a fusion weapon. We have to use fission, or, rather, the energy created by that, to initiate the fusion reaction. It might be possible to use a high power source, like a laser, on a small amount of material to get fusion to occur. But we are still experimenting with this in the Tokamak, and it's far from being a done deal. Stars are, in general, massive nuclear fusion reactors. Their constant consumption of fuel powering their high rate of fusion creates a massive amount of energy, and the stars' huge gravity keeps this process from blowing the whole thing apart. No fission is needed to sustain this reaction.
How can you destroy xenon?
Xenon is a chemically inert noble gas and is not easily destroyed. High temperatures and pressures or reactions with highly reactive elements such as fluorine or oxygen are needed to react with xenon. However, these methods may not completely "destroy" xenon but rather form other compounds containing xenon.

What is the significance of the heat of plasma in the study of nuclear fusion reactions?
The heat of plasma is important in nuclear fusion reactions because it helps to initiate and sustain the fusion process. Plasma, which is a superheated state of matter, is necessary for the atoms to collide with enough energy to overcome their natural repulsion and fuse together. The high temperatures of the plasma create the conditions needed for nuclear fusion to occur, releasing large amounts of energy in the process.
Do fusion bombs leave a trail of nuclear radiation like a fission bomb after they explode?
Great question, nicely worded except I'm not sure what you mean be "trail". If by "trail" you mean windblown fallout plume, then yes and usually much bigger because their yield is bigger. Even though a fusion bomb is called a fusion bomb, the standard design generates about 90% of its yield from fission because the high energy fusion neutrons make the depleted uranium tamper fission, which also generates most of the bomb's fallout. In the 1956 Redwing series in the pacific, the US tested the world's first "clean" fusion bombs at Bikini atoll; 2 devices, 1 of which had as little as 5% of its yield from fission most of which was believed to be due to the fission trigger and the rest the fission "sparkplug". This reduced fallout dramatically, though the yield was also reduced and more lithium-deutride fuel was needed making the "clean" bomb more expensive than a standard one.
How do gravity temperature and pressure impact and affect nuclear fusion?
Gravity plays a crucial role in nuclear fusion by compressing and heating the stellar core to the high temperatures and pressures needed for fusion to occur. Higher temperatures and pressures increase the likelihood of atomic nuclei overcoming their mutual repulsion and fusing together. These conditions are found in the cores of stars, where gravity provides the necessary confinement and energy to sustain nuclear fusion reactions.
How did the atomic bomb become outdated?
The fission bomb never became outdated, one is needed in every single fusion bomb as the primary to set off the fusion reaction.
What is the minimum amount of material needed to sustain a nuclear reaction?
The minimum amount of material needed to sustain a nuclear reaction depends on the type of reaction. For example, in a nuclear fission reaction, a critical mass of fissile material is needed to sustain a chain reaction. In a fusion reaction, high temperatures and pressures are needed to overcome the electrostatic repulsion between nuclei.
