Helium shows Bose-Einstein condensation below what temperature?

Helium shows Bose-Einstein condensation below what temperature? Correct Answer 2.13 K

When cooled below 2.13 K, a transition occurs and liquid helium in this state shows super fluidity. It shows to have no viscosity and it can go through very narrow slits. It becomes a Bose-Einstein Condensate.

If the solubilities of different components (in a liquid-liquid extraction system) increase with rise in temperature, then the temperature above which they dissolve completely is known as the critical solution temperature (CST or consolute temperature). If solubilities increase with decrease in temperature, then CST is the temperature below which they dissolve completely. If a binary system has no critical solution temperature, it implies that
