i did not understand bose einstien condensate

Bose-Einstein Condensate  is also known as the fifth state of matter. Indian scientist Satyendra Nath Bose is credited for its discovery with significant contribution from Albert Einstein as well. The particles of this state are called bosons. These bosons are subatomic particles with integral spins i.e., 0, 1, 2 and so on. It is formed by cooling a gas of extremely low density to very low temperatures. Because of this super low temperature, the bosons come very close to each other. You will study about this state of matter in more detail in higher grades.
