At extremely high temperatures (e. g., millions of degrees), which of the following best describes the phase of matter?

a. a gas of rapidly moving molecules

b. a plasma consisting of rapidly moving, neutral atoms

c. a plasma consisting of positively charged ions and free electrons

d. a gas consisting of individual, neutral atoms, but no molecules

c. a plasma consisting of positively charged ions and free electrons

Explanation:

Plasma is a state of matter which occurs at extremely high temperatures.

In this state, the particles of matter are ionized, that is, they are electrically charged.

The higher the temperature the particles move at a higher speed, the atoms collide with each other at speeds so high that an evolution of electrons in the collision is caused.
