Expert Answer
Plasmas are known as the fourth state of matter. They are "hotter" than gas. A plasma occurs when the temperature is between 1000 degrees C and 1,000,000,000 degrees C. Some examples of plasma are flames, lightning, aurora (northern lights), neon lights, and stars, including our own sun.
The "Bose-Einstein condensate is the fifth state of matter. An example is helium-4 close to absolute zero in the superfluid state, in which it will attempt to 'climb' out of its container.
A Bose-Einstein condensate is "colder" than a solid. It occurs when atoms have very similar (or the same) quantum levels. Temperatures close to absolute zero (-273 °C) will exhibit the Bose-Einstein condensate.
