Is liquid nitrogen an example of Bose Einstein condensates?
As of 2010, the Bose-Einstein condensate state of matter has
only been achieved in temperatures of 10-7 K in many alkali and
alkaline earth metals' isotopes.
They include: 7Li, 23Na, 39K, 41K, 85Rb, 87Rb, 133Cs, 52Cr,
40Ca, 84Sr, 86Sr, 88Sr, and 174Yb
