Expert Answer
The two more states of matter discovered are: Plasma and Bose-Einstein Condensate.
Plasma: It is a mixture of free electrons and ions. It occurs naturally in the stars. It is made on earth by passing electricity through gases at very low pressures taken in a glass tube (discharge tube).
Bose Einstein Condensate (BEC): It is obtained by cooling a gas of extremely low density (about one-hundred thousandth the density of normal air) to super low temperatures.
