Question

What is the cause of random motion of electrons in metal?

Answer 1

Let's make it crisp and clear

Everything has some random motion. Thermometers give one way of measuring how much random motion there is. High temperature means the little parts are jiggling around more. This happens because there are many more states with things moving around than there are states with everything locked in place. What is sort of special about the electrons in conductors is that they can move rather quickly across a material, rather than just jiggling around in a small region, like atoms in a solid.

P.s; Mark me as brainliest.
