Quizplus · Accepted Answer

A plasma is a gas that has been ionized, which means it has free electrons and positively charged ions. This results in the ability of the plasma to conduct electricity, which is not a characteristic of a normal gas. While a plasma can be hotter than a gas, this is not always the case. The distance between molecules does not change when a gas becomes a plasma, so A and D are incorrect. Therefore, the best choice is C, as it is the only characteristic that distinguishes a plasma from a normal gas.
