Question

Explain 4th state of matter.

Answer 1

Explanation:

Plasma, in physics, an electrically conducting medium in which there are roughly equal numbers of positively and negatively charged particles, produced when the atoms in a gas become ionized. It is sometimes referred to as the fourth state of matter, distinct from the solid, liquid, and gaseous states.

Answer 2

Answer:

But if you heat gas, its atoms will break apart into negatively charged electrons and positively charged ions. This soup of electrons and ions is plasma--the fourth state of matter. It was discovered by William Crookes in 1879.
