Question

Bose-Einstein condensate state is obtained by cooling of the substance below _____.

• A. $-{273}^{0}C$
• B. ${273}^{0}C$
• C. $273K$
• D. $295K$

Answer 1

The correct option is A $-{273}^{0}C$

Bose-EInstein condensate (BEC) is the fifth state of matter which is obtained by supercooling of the substance below $-{273}^{0}C$. This state of matter is artificially prepared in a laboratory because it is difficult to obtain such a low temperature naturally.
