Yes, high pressure is required for a fusion reaction to occur because it helps bring the nuclei close enough together for the strong nuclear force to overcome the electrostatic repulsion between positively charged nuclei. The high pressure creates conditions similar to those found in the core of stars where fusion naturally occurs.

Which conditions are required to form 4 2he during the fusion reaction in the sun?
For 4 helium nuclei to form during the fusion reaction in the sun, high temperatures (around 15 million degrees Celsius) and high pressures are required to overcome the electrostatic repulsion between the positively charged nuclei and facilitate the nuclear fusion process. Additionally, a sufficient amount of hydrogen nuclei (protons) must be present to undergo the series of nuclear reactions that eventually lead to the formation of helium.
What two things are necessary for fusion reaction to take place in a star?
High temperature and high pressure are necessary for fusion reactions to take place in a star. The high temperature is needed to overcome the electrostatic repulsion between positively charged atomic nuclei, while the high pressure is needed to confine the high temperature plasma.
What is a significant difficulty in using fusion as an energy source?
One significant difficulty in using fusion as an energy source is the challenge of containing and controlling the extremely high temperatures and pressures required for the fusion reaction to occur.
Why does the plasma in a fusion reactor need to be very hot?
The plasma in a fusion reactor needs to be very hot to achieve the high temperature and pressure conditions required to overcome the electrostatic repulsion between positively charged atomic nuclei and initiate the fusion reaction. This high temperature allows the atomic nuclei to collide with enough energy to overcome the electrostatic barrier and fuse together, releasing energy in the process.
When does thermonuclear fusion reaction start?
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

Why is the sun's energy generated mostly at its center and not near its surface?
At the center, both the temperature and the pressure are highest. Both a high pressure and a high temperature increase the likelihood of fusion.

What is the major problem with fusion reactions as an energy source?
Problem on nuclear fusion is upon confinement of reaction in earth atmosphere. Nuclear fusion required very high temperature to initiate the reaction. Sustaining reaction is not easy. It is likely the earliest nuclear fusion will be available commercially by 2050. It is a little far future for the current energy crisis would reach it peak around 2040.

What conditions are present in stars that cause the hydrogen to form helium?
The extreme pressure and temperature in a star's core cause hydrogen atoms to undergo nuclear fusion, combining to form helium. This fusion process releases a great amount of energy, helping to sustain the star's luminosity.
What kind of proton causes a nuclear reaction?
A proton with high energy and momentum is required to initiate a nuclear reaction. When this high-energy proton collides with another nucleus, it can cause it to undergo fission or fusion, releasing a large amount of energy.
What is fusion ignition?
Fusion ignition refers to the manner in which a fusion reaction is "ignited" to make it happen. In nature stars, which are huge fusion reactors, using their enormous pressure to compress and heat matter (mostly hydrogen) when they are first formed. This massive heating and pressure "triggers" or "ignites" the fusion chain reaction. The chain will then be sustained by the heat given off during the fusion process, with massive gravity keeping the whole thing "under control" or "in one place" so it will continue. During this process the hydrogen is pushed/compressed together so far that it goes past the repulsive nuclear forces (which produces the nuclear fusion energy) and is then converted into the element known as helium. This refers to reaching the very high temperature required to achieve nuclear fusion. It could be in a tokamak type reactor such as JET, or the laser being built in California
Nuclear fusion can only occur in areas of?
In areas of high temperature and high pressure
Nuclear fusion powers the sun what elements are fused together in the sun?
It is just protons joining together, which are hydrogen ions, so the only fuel required is hydrogen, the reaction proceeds due to the high pressure at the sun's core, due to the immense gravitational compression. See the link below
