Which reason best explains why plasmas are good conductors of electricity? They have mobile charged particles. They are at extremely high temperatures. They are made up of particles in fixed positions. They have slow-moving nuclei that carry electricity.

They have mobile charged particles.

Explanation:

Plasma refers to very hot matter such that the electrons in matter are ripped away from the atoms leading to the formation of an ionized gas.

We know that the carriers of electricity are charged particles. Any state of matter that has an abundance of charge carriers will definitely be a good conductor of electricity.

Therefore, plasmas are good conductors of electricity because they have a lot of mobile charged particles.

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."
