Question

which is an aspect of the kinetic-molecular theory and can be used to explain the behavior of plasmas?
○ particle spacing can allow a very high density.
○ particle kinetic energy is independent of temperature.
○ particles vibrate quickly in stationary positions.
○ particles exchange energy through elastic collisions.

Explanation:

Kinetic-molecular theory states that particles in gases (and plasmas, which are ionized gases) exchange energy via elastic collisions, with no net energy loss. This explains plasma particle interactions. The other options are incorrect: plasmas have low density, particle kinetic energy depends on temperature, and plasma particles do not vibrate in fixed positions.

Answer:

D. Particles exchange energy through elastic collisions.
