Question

At extremely high temperatures (e.g., millions of degrees), which of the following best describes the phase of matter? At extremely high temperatures (e.g., millions of degrees), which of the following best describes the phase of matter? a gas of rapidly moving molecules a gas consisting of individual, neutral atoms, but no molecules a plasma consisting of positively charged ions and free electrons a plasma consisting of rapidly moving, neutral atoms none of the above (At these extremely high temperatures, matter cannot exist.)

Answer 1

(C.) A plasma consisting of positively charged ions and free electrons

Step-by-step explanation:

Plasma and ionized gases have properties and display behaviors unlike those of the other states, and the transition between them is mostly a matter of nomenclature and subject to interpretation.

Based on the temperature and density of the environment that contains a plasma, partially ionized or fully ionized forms of plasma may be produced.

Plasma is a state of matter in which an ionized gaseous substance becomes highly electrically conductive to the point that long-range electric and magnetic fields dominate the behaviour of the matter. The plasma state can be contrasted with the other states: solid, liquid, and gas.

Plasma is an electrically neutral medium of unbound positive and negative particles (i.e. the overall charge of a plasma is roughly zero). Although these particles are unbound, they are not "free" in the sense of not experiencing forces. Moving charged particles generate an electric current within a magnetic field, and any movement of a charged plasma particle affects and is affected by the fields created by the other charges.
