What is Bose-Einstein condensate short answer?
Bose-Einstein condensate (BEC), a state of matter in which separate atoms or subatomic particles, cooled to near absolute zero (0 K, − 273.15 °C, or − 459.67 °F; K = kelvin), coalesce into a single quantum mechanical entity—that is, one that can be described by a wave function—on a near-macroscopic scale.
What is Bose-Einstein condensate Wikipedia?
In condensed matter physics, a Bose–Einstein condensate (BEC) is a state of matter that is typically formed when a gas of bosons at low densities is cooled to temperatures very close to absolute zero (−273.15 °C or −459.67 °F).
What is Bose-Einstein condensate kid definition?
Kids Encyclopedia Facts. Bose–Einstein condensate (BEC) is what happens to a dilute gas when it is made very cold, near absolute zero (0 K which equals −273.15 °C or −459.67 °F). It forms when the particles that make it up have very low energy. Only bosons can make a Bose–Einstein condensate.
What are the characteristic features of particles obeying Bose-Einstein statistics?
The aggregation of particles in the same state, which is characteristic of particles obeying Bose-Einstein statistics, accounts for the cohesive streaming of laser light and the frictionless creeping of superfluid helium.
What is Bose-Einstein condensate in chemistry class 9?
BEC stands for Bose-Einstein Condensate which is defined as the state of matter of a dilute gas of bosons that is cooled to temperatures very close to absolute zero. Bose-Einstein condensate refers to the breakdown of atoms into a single quantum state.
What are the assumption of Bose-Einstein statistics?
The Bose–Einstein statistics applies only to the particles not limited to single occupancy of the same state – that is, particles that do not obey the Pauli exclusion principle restrictions. Such particles have integer values of spin and are named bosons.
What is the process of Bose Einstein condensate?
A Bose-Einstein condensate is a group of atoms cooled to within a hair of absolute zero . When they reach that temperature the atoms are hardly moving relative to each other; they have almost no free energy to do so. At that point, the atoms begin to clump together, and enter the same energy states.
What are some examples of Bose Einstein condensates?
Two examples of Bose-Einstein condensates include superfluids, such as cold liquid helium, or superconductors, such as the nucleons inside a neutron star.
What is the use of Bose Einstein?
Viewed as a pure probability distribution, the Bose-Einstein distribution has found application in other fields: In recent years, Bose-Einstein statistics have also been used as a method for term weighting in information retrieval .
What state of matter is Bose Einstein?
Bose Einstein Condensate is the fifth state of matter (after solid, liquid, gas, plasma). To visualize the fifth state of matter one needs to have the cooling capacity to lower gas temperature to very near the absolute zero (less than one-millionth of a degree above absolute zero).
