Yogita Ingle 7 years, 5 months ago

Bose-Einstein condensate is a state of matter that arises because of quantum mechanical effects on a collection of entities called bosons. These bosons are the particles with integral spins i.e., 0, 1, 2 and so on. These boson form condensate when cooled to temperatures very near to absolute zero. Helium–4 forms this condensate. At absolute zero temperature, it becomes a superfluid. Superfluidity means that a fluid having infinite thermal conductivity and having no viscosity.
