Nuclear fusion occurs at the core of the sun (and other stars) providing huge amount of energy to the rest of the solar system. It has also been achieved on Earth, though not in a controlled and sustained manner.
No. A white dwarf is the remnant of a star in which fusion as stopped.
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.
Not enough pressure or temperature.
No. Fusion has long since ceased by the time a stellar remnant becomes a black dwarf.
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.
How can temperature either help fusion to occur or prevent fusion from occurring?
Fusion occurs in the sun.
Fusion occurs in the sun.
Fusion occurs in the core of the Sun
The temperature required for nuclear fusion to occur is around 100 million degrees Celsius.
Fusion occurs in the core of the sun and other stars.
heat and pressure
Because the conditions of temperature and pressure that occur in stars do not occur on earth
nuclear fusion is not a natural occurrence, it is when two atoms are fused together
No. A white dwarf is the remnant of a star in which fusion as stopped.
