What do you mean by B.E.C.?

Bose-Einstein condensate(B.E.C):

1. Bose-Einstein Condensate, or BEC, is a state of matter that results from cooling diluted gas of bosons to temperatures very close to absolute zero.
2. Around$1924$, Satyendra Nath Bose and Albert Einstein made the first proposal for BEC.
3. The atoms are hardly moving with respect to one another when they reach that temperature because they have almost little free energy to do so.
4. The atoms then start to group together and transition into the same energy levels. Physically they merge into one another, and the entire group begins to behave as though it were a single atom.
5. Also, atoms breaking down into a single quantum state are referred to as a Bose-Einstein condensate.
6. The atoms in a Bose-Einstein condensate (BEC) are complete opposites of plasmas(electrons move freely in this state of matter), which are extremely hot and energetic. They are extremely chilled and unexcited atoms.

Therefore, B.E.C stands for Bose-Einstein condensate and it refers to the breakdown of the atom into a single quantum state.
