state of matter plasma true A physical quality that inheres in a bearer by virtue of its plasma is a state of matter, that is, it does not have definite shape or volume. Unlike gases, plasmas are electrically conductive, produce magnetic fields and electric currents, and respond strongly to electromagnetic forces. Positively charged nuclei swim in a "sea" of freely-moving disassociated electrons, similar to the way such charges exist in conductive metal. [Wikipedia] plasma state of matter plasma
