At extremely high temperatures, matter can exist in the form of plasma, which is a state of matter consisting of positively charged ions and free electrons. This occurs when the temperature is high enough to ionize the atoms, separating the electrons from the nuclei. Plasma is often referred to as the fourth state of matter, after solid, liquid, and gas.
