What are the two recently discovered states of matter?
Answers
Answer:
Apart from the three-commonly known states of matter, there exist other two states of matter which are much talked about: Plasma and Bose-Einstein Condensate.
Plasma: Plasma state is the 4th state of matter which is an ionized gas. Plasma neither has a definite volume nor a definite shape. It can be defined as a gaseous substance into which sufficient energy is provided to free electrons from atoms or molecules and to allow both species i.e. ions or electrons to co-exist. Examples of plasma are Stars, lightning, etc. Plasma is also present inside the fluorescent lights.
Bose-Einstein Condensate: Bose-Einstein Condensate (BEC) is a state of matter of a dilute gas of bosons (a boson is a particle that follows Bose-Einstein Statistics) cooled to a temperature very close to absolute zero. In simple words, BEC is formed by cooling a gas of extremely low density.
The state of matter in which separate atoms or subatomic particles are cooled down absolute zero temperature is called as Bose-Einstein condensate. Bose-Einstein condensate is latest discovered state of matter.
