What is the critical temperature at which nuclear reactions begin?

For nuclear fission reactors there is no critical temperature, though they do have a temperature coefficient which makes the efficiency of the chain reaction vary slightly with temperature. This can be negative or positive, obvously a negative coefficient is preferred and is safer. Nuclear fusion is another matter, and very high temperatures are required in tokamaks to get fusion started


In which part of a newborn star does the fusion reactio occur?

In a newborn star, the fusion reactions occur primarily in its core, where the temperature and pressure are high enough to trigger nuclear fusion. This process generates the energy that powers the star and allows it to shine bright.


How does nuclear fusion within the sun take place within the core of the star?

Nuclear fusion in the sun's core occurs when hydrogen atoms combine to form helium under high pressure and temperature, releasing energy in the process. This process is sustained by the sun's immense gravitational force, which creates the necessary conditions for fusion to occur.


What takes an extremely high temperature for nuclear what?

Nuclear fusion reactions require extremely high temperatures, typically in the range of 100 million to 150 million degrees Celsius, in order to overcome the electrostatic repulsion between positively charged atomic nuclei and allow them to fuse together. This extreme heat is needed to create the conditions necessary for the fusion process to occur and release energy.


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.

Does nuclear fusion happen in the convection zone?

No, nuclear fusion does not occur in the convection zone of a star. Fusion reactions primarily take place in the core region of a star, where the temperature and pressure are high enough to sustain the nuclear reactions that power the star. The convection zone is a region of the star where heat is transported through the movement of gas, but fusion does not occur there.

When does nuclear fusion occur?

nuclear fusion is not a natural occurrence, it is when two atoms are fused together

Where does nuclear fusion occur in a nuclear plant?

Nuclear fusion does not currently occur in nuclear plants. Nuclear plants use nuclear fission, where atoms are split to release energy. Fusion reactions, in which atomic nuclei combine to release energy, are not yet used commercially for electricity generation.


It takes an extremely high temperature for nuclear to occur inside the sun?

Not nuclear, it takes an extremely hight temperature for Fusion to occur with in the sun or any other star. ADDED: Yes "nuclear". Fusion is one of the two type of nuclear reaction, the other being Fission.


Two main forces in a star?

The two main forces in a star are gravity and nuclear fusion. Gravity pulls matter inward, compressing it and creating the high pressure and temperature needed for nuclear fusion to occur. Nuclear fusion releases energy as light and heat, which counteracts the force of gravity trying to collapse the star.


Does nuclear fusion occur at a low temperature?

No, normally it occurs at temperatures of millions of degrees. It does occur at room temperature, but not in significant amount; any possible practical use of "cold fusion" is, so far, speculation.


How does nuclear fusion generate the suns energy?

Nuclear fusion in the sun occurs when hydrogen atoms combine to form helium atoms. This process releases large amounts of energy in the form of photons. The intense pressure and temperature in the sun's core create the conditions necessary for nuclear fusion to occur.
