Bose-Einstein Condensate (BEC) is formed by cooling a gas of extremely low density

• GC Matter

Bose-Einstein Condensate (BEC) is formed by cooling a gas of extremely low density, about one-hundred-thousandth the density of normal air. This is treated as

1. II state of matter
2. III state of matter
3. IV state of matter
4. V state of matter

Answer

The fourth state of matter is plasma. Majority of the stuff in the space is Plasma.

The fifth state of matter is BEC (Bose-Einstein Condensate). BEC is a state of matter of a dilute gas of bosons cooled to near absolute zero (0 K or -273.15 °C). A BEC is formed by cooling a gas of extremely low density, about one-hundred-thousandth the density of normal air, to ultra-low temperatures.

The correct option is D.
