Question

30. The random motion of holes and free electrons due to thermal agitation is called
(A) ionisation
(B) pressure
(C) diffusion
(D) None​

Answer 1

Ionisation – this is the ejection of electrons away from the orbit of an atom, hence giving the atom a net positive charge. ... From these, we can conclude that the random motion of holes and electrons due to thermal agitation is diffusion.

Answer 2

Answer:

Ionisation

Explanation:

The random motion is ionisation
