To bond together, two nuclei must be thrown together with great force. This is because every nucleus has a positive charge and the nuclei repel each other when they come close. If that resistance is overcome and the nuclei actually begin to impact each other, then it is possible for one proton in one nucleus to change to a neutron and bind or 'fuse' together with the other nucleus.
The great force required here includes both extreme heat and extreme pressure, comparable to that inside stars.
What else can I help you with?
Inside a prostar the nuclear fusion of hydrogen will begin when?
The core of the protostar reached an extremely high temperature
Does the onset of fusion reactions inside stars require high or low density and high or low temperature?
The onset of fusion reactions inside stars requires high density and high temperature. The high density is needed to bring atomic nuclei close enough together for the strong nuclear force to overcome electrostatic repulsion, allowing the nuclei to fuse. The high temperature is required to provide the particles with enough kinetic energy to overcome the electrical repulsion and fuse.
What layer of the sun does fusion occur?
Nuclear fusion occurs in the solar core.
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.
Why are claims that nuclear fusion occurs at room temperature unrealistic?
Actually room temperature nuclear fusion has been verified by reputable scientists, but it only works with muonic-hydrogen. This is hydrogen with its electron replaced by a muon, a particle identical to the electron except that it weighs 200 times as much. Because of the extra mass the muon orbits the proton much closer than the electron does. This allows muonic-hydrogen nuclei to collide and fuse at room temperature. However it takes far more energy to make the muons and replace them for the electrons than can be obtained from the fusion.
What take an extremely high temperature for nuclear?
Nuclear fusion requires extremely high temperature and great pressure.
Nuclear fusion can only occur in areas of?
In areas of high temperature and high pressure
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.
Why very high temperature exist around the sun?
Because of the nuclear fusion that it does.
At 15.6 million degrees Celsius the temperature of the Suns core is high enough for nuclear what to occur?
For nuclear fusion.
Why does the sun give of energy?
The high temperature and pressure in the Sun's interior causes nuclear fusion.
Inside a prostar the nuclear fusion of hydrogen will begin when?
The core of the protostar reached an extremely high temperature
Does the onset of fusion reactions inside stars require high or low density and high or low temperature?
The onset of fusion reactions inside stars requires high density and high temperature. The high density is needed to bring atomic nuclei close enough together for the strong nuclear force to overcome electrostatic repulsion, allowing the nuclei to fuse. The high temperature is required to provide the particles with enough kinetic energy to overcome the electrical repulsion and fuse.
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.
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.
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.
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
