Aplasma that has particles that never collide frequently enough to exchange kinetic energy and never reach a temperature equal to the surroundings is categorized as a
thermal plasma.
ionized plasma.
low density plasma.
nonthermal plasma.

I took the test, yes it is Nonthermal plasma

Option (d) is the correct answer.

Explanation:

Plasma is defined as the state of matter which is a hot gas containing both positively charged ions and negatively charged electrons.

A non-thermal plasma is defined as a plasma that has particles which never collide frequently enough to exchange kinetic energy and never reach a temperature equal to the surroundings.

On the other hand, a plasma which tends to reach a temperature equal to its surrounding is known as thermal plasma.

Plasma created at lower temperature (usually cold) will have low density plasma.

Therefore, we can conclude that a plasma that has particles that never collide frequently enough to exchange kinetic energy and never reach a temperature equal to the surroundings is categorized as a non-thermal plasma.
