Plasma is one of the four basic states of matter among solid, liquid, and gas. Thermal plasmas reach higher temperatures as well as reach thermal equilibrium. hot plasmas are created by heating a gas until electrons have reach an energy that break free from the atoms.
There are other states of matter, and a plasma is a state of extreme energy. For instance, a star like our sun is a big ball of plasma. And plasma is a collection of atoms that have so much thermal energy that all their electrons have been boiled off due to extreme heating.
