Question

In the core of nuclear fusion reactor, the gas becomes plasma because of

• A. strong nuclear force acting between the deuterons
• B. Coulomb force acting between the deuterons
• C. Coulomb force acting between deuteron-electron pairs
• D. the high temperature maintained inside the reactor core

Answer 1

Answer: (D)

the high temperature maintained inside the reactor core

The gas becomes plasma because of the high temperature. The kinetic energy of the particles are directly proportional to absolute temperature, the high temperature causes the particles to turn into plasma (from gas).
Hence option D is correct.
