EXPERT ANSWER

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.

Examples of Bose Einstein Condensate are:

  • Super conductors
  • Super fluids

Plasma is the fourth state of matter. It is the ionized form of atoms of dissociated gas which contains positively and negatively charged particles. Therefore they have electrostatic forces between them, but the overall charge on it is almost zero.

It has the property unlike solid, liquid and gas. It can be considered a distinct state of matter.

Examples of Plasma:

  • Lightning
  • Ionosphere
  • Extremely hot flames
  • Suns and stars
  • Solar winds
