In the sun and all the other stars it is going on all the time, using the hydrogen contained at great pressure and temperature at the star's core. Controlled fusion on earth has not been achieved yet except for a brief period, less than 1 second, and this involved heating a gas plasma containing hydrogen isotopes to very high temperature, hundreds of millions of degrees, in a torus shaped device known as a tokamak. A magnetic field constrains the ionised plasma into a circular path. This type of device may be successful in the future in achieving steady fusion power, but it will take many years to develop.
The other occurrence is in H-bombs.
What else can I help you with?
Does fission or fusion occur in the sun?
Fusion occurs in the sun.
Does fusion or fission occur in the sun?
Fusion occurs in the sun.
What is the temperature required for nuclear fusion to occur?
The temperature required for nuclear fusion to occur is around 100 million degrees Celsius.
Can fission occur after fusion?
No, fission and fusion are two distinct nuclear reactions. Fusion involves the joining of atomic nuclei to release energy, while fission involves the splitting of atomic nuclei. They are not directly connected processes, so fusion does not lead to fission.
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.
How can temperature either help fusion to occur or prevent fusion from occurring?
How can temperature either help fusion to occur or prevent fusion from occurring?
Does fission or fusion occur in the sun?
Fusion occurs in the sun.
Does fusion or fission occur in the sun?
Fusion occurs in the sun.
Where does the fusion reacion occur on the sun?
Fusion occurs in the core of the Sun
What is the temperature required for nuclear fusion to occur?
The temperature required for nuclear fusion to occur is around 100 million degrees Celsius.
Where does the fusion reaction occur in the sun?
Fusion occurs in the core of the sun and other stars.
What makes fusion occur?
heat and pressure
Why does nuclear fusion not occur on earth?
Because the conditions of temperature and pressure that occur in stars do not occur on earth
When does nuclear fusion occur?
nuclear fusion is not a natural occurrence, it is when two atoms are fused together
Does fusion occur in white dwarf stars?
No. A white dwarf is the remnant of a star in which fusion as stopped.
Does hydrogen fusion occur in the corona?
Hydrogen fusion does not occur in the corona of the sun. Fusion reactions occur in the sun's core where conditions are hot and dense enough for hydrogen nuclei to combine to form helium, releasing energy in the process. The corona is cooler and less dense than the core, so fusion cannot take place there.
Where does nuclear fusion occur in any star?
