What is an aspect of the kinetic-molecular theory and can be used to explain the behavior of plasmas?

A plasma is a hot ionised gas which has equal number of positively charged particles and negatively charged electrons. Plasma are considered to be the fourth state of matter. Because plasma are made up of charged particles they are affected by both electric and magnetic field. The aspect of the kinetic molecular theory that can be used to explain the behaviour of plasma is that PARTICLES IN MOTION EXCHANGE ENERGY THROUGH ELASTIC COLLISION.

Because a model would make the investigation easier to understand
