Question

Which of the following is not true of a plasma?
Options
A Plasma consists of a collection of free-moving electrons and ions
B Energy is needed to strip electrons from atoms to make plasma.
C The energy in forms of thermal, electrical, or ultraviolet light are always use
D With sufficient sustaining power, plasmas recombine into neutral gas.
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

Without sufficient sustaining energy, plasmas recombine into neutral gas. The statement says 'with sufficient sustaining power'—that would maintain the plasma, not cause recombination.

Hint

Recombination occurs when energy is removed, not added.
