Question

Bose-Einstein Condensate have
A. Very low kinetic energy
B. Low kinetic energy
C. High kinetic energy
D. Highest kinetic energy.

Answer 1

A Bose-Einstein condensate is a collection of atoms that have been cooled to within a few degrees of absolute zero. When they reach that temperature, atoms have practically little free energy to move about in relation to one another. The atoms begin to cluster together and enter the same energy levels at this stage. From a physical standpoint, they become identical, and the entire group begins to behave as if it were a single atom.

Complete answer:
A Bose–Einstein condensate (BEC) is a state of matter (also known as the fifth state of matter) that is created when a gas of bosons at low densities is cooled to temperatures extremely near to absolute zero ($273.15\text{ }{}^\circ C$ or $459.67\text{ }{}^\circ F$) in condensed matter physics.

A substantial percentage of bosons inhabit the lowest quantum state under these conditions, at which point tiny quantum mechanical phenomena, notably wavefunction interference, become visible macroscopically. A BEC is created by chilling an extremely low-density gas to ultra-low temperatures (approximately one-hundredth ($\dfrac{1}{100,000}$) the density of regular air).

Chilling a liquid or solid to absolute zero temperature produces the Bose einstein condensate. It is produced when the temperature lowers and the kinetic energy of the particles decreases as a result. The condensate function is created when the temperature lowers to a point where the item's kinetic energy is considerably less than its potential energy.As a result, the right answer is Low Kinetic Energy.

Hence, the correct answer is option B.

Note: A diffuse gas cloud is used to create a Bose-Einstein condensate. Many experiments begin with rubidium atoms. Then you use lasers to cool it down, removing energy from the atoms with the beams. After that, scientists employ evaporative cooling to chill them down even further. "You start from a disordered state with a [Bose-Einstein condensate], where kinetic energy is larger than potential energy," said Xuedong Hu, a physics professor at the University at Buffalo. "You cool it down, but it doesn't solidify into a lattice."
