Describe Some Bec Examples.

Superfluids and superconductors, such as the neutrons inside a neutron star, are two examples of BEC. Another state of matter, similar to solids but with less energy, is a Bose-Einstein condensate. A Bose-Einstein Condensate is a state of matter produced when particles called bosons are cooled to nearly absolute zero (-273. Celsius, or -460. Fahrenheit). It is sometimes referred to as the fifth state of matter.For many years, liquid helium served as the standard illustration of Bose-Einstein condensation. The viscosity vanishes and the behavior of liquid helium changes from that of an ordinary liquid to that of a so-called superfluid.A collection of atoms cooled to a tiny fraction of absolute zero is known as a Bose-Einstein condensate. Since they have almost no free energy to do so, the atoms are hardly moving in relation to one another when they reach that temperature. At that point, the atoms start to group together and transition into one another’s energy states.Lasers are used to cool and trap an atom gas. The hottest atoms are then allowed to escape from a magnetic trap, creating the Bose-Einstein condensate, a gas that is so cold and dense that it condenses into a superatom.

What other names are used to refer to BEC?

Business email compromise (BEC), also referred to as email account compromise (EAC), is one of the most financially damaging online crimes. It takes advantage of the fact that so many of us conduct business, both personal and professional, via email. Business email compromise (BEC) is a type of cybercrime where the scammer uses email to coerce a victim into sending money or disclosing sensitive company information.A security vulnerability known as a business email compromise (BEC) occurs when an attacker chooses a target with access to company funds and successfully persuades the victim to transfer funds to the attacker’s bank account.

What is BEC class 11 of matter?

A diluted gas of bosons that has been cooled to temperatures very close to absolute zero (that is, very close to 0 K or? C) is said to have reached a state of matter known as a Bose-Einstein condensate (BEC). When a significant portion of bosons occupy the lowest quantum state, macroscopic quantum phenomena start to emerge. When a gas of bosons with very low densities is cooled to temperatures that are very close to absolute zero (273. C or 459. F), a Bose-Einstein condensate (BEC), a state of matter, typically forms.Future electronics may benefit greatly from superconductors, which are substances in which electricity flows without any resistance at all. For the first time ever, scientists and engineers at the University of Tokyo have been able to convert a Bose-Einstein condensate (BEC) into a superconductor.Satyendra Bose and Albert Einstein were the first to predict the BEC phenomenon: a group of identical Bose particles will collectively transition to the lowest energy state, or a BEC, when they come close enough to one another and move slowly enough.BECs are connected to two remarkable low-temperature phenomena: superfluidity, in which the helium isotopes 3He and 4He combine to form a fluid that flows without resistance; and superconductivity, in which electrons flow through a material with no electrical resistance.The collective low-energy state of bosons is known as a Bose-Einstein condensate (BEC), and it has been discovered to exist not only in extremely cold atomic gases but also at higher temperatures in materials hosting bosonic quasiparticles like magnons, excitons, and polaritons.

What does BEC mean in ninth-grade chemistry?

A state of matter known as Bose-Einstein condensate, or BEC, is created when a diluted gas of bosons is cooled to temperatures very close to absolute zero. A diluted gas of bosons that has been cooled to temperatures extremely close to absolute zero (i. K or? C) is known as a Bose-Einstein condensate (BEC). When a significant portion of bosons occupy the lowest quantum state, macroscopic quantum phenomena become visible.Bose-Einstein condensate is the most recent state of matter to be identified. When cooled to almost absolute zero, it is a state of matter in which different atoms or subatomic particles combine to form a single quantum mechanical entity.The coldest effective temperature ever measured—38 pK (10–12 K) above absolute zero—was attained by using a novel method to control the expansion of matter in a freely falling Bose–Einstein condensate (BEC).Eric A. Bose-Einstein condensate (BEC). Carl, Cornell, and Wolfgang Ketterle. E. Physicist Wieman won the Nobel Prize this year.A special phase known as a Bose-Einstein condensate, where all the particles have the same quantum state, is sometimes referred to as the fifth state of matter. In 1924, Satyendranath Bose and Albert Einstein made the prediction that this phase would occur.

What type of gas is used to create BEC?

The original BEC was a gas of rubidium atoms, but a BEC with dipolar interactions can also be created using other atoms, like dysprosium. The original BEC was a gas of rubidium atoms, but it is possible to create a BEC with dipolar interactions by using other atoms, such as dysprosium. In contrast to a typical BEC, a dipolar BEC’s atoms have two opposing poles that resemble the ends of a magnet.The fact that so little is known about BECs may make them the most intriguing to researchers. Although BEC-like gases are not naturally occurring on Earth, some theorize that the high pressure surroundings of neutron stars may give rise to them (1).A Bose-Einstein condensate (BEC) is a state of matter in condensed matter physics that typically develops when a gas of bosons with extremely low densities is cooled to temperatures very close to absolute zero (273. C or 459. F).Since scientists Satyandra Nath Bose and Albert Einstein predicted the Bose-Einstein Condensate (BEC) almost a century ago, researchers have been studying it for decades. A gas of atoms that has been cooled to nearly absolute zero is the BEC.

Is liquid helium considered a BEC?

Up until 1995, the superconductors known as Cooper pairs and superfluid helium-4 and helium-3 were the only sources of Bose-Einstein condensation (BEC). These systems exhibit unusual phenomena due to their strong interactions, but they also present unusual theoretical difficulties. The fifth state of matter, or Bose-Einstein condensate (BEC), is a diluted gas of bosonic atoms whose temperature is so low that the distance between one atom and the next is comparable to the wavelength of the gas.The BEC phenomenon was first predicted by Satyendra Bose and Albert Einstein: a given number of identical Bose particles will collectively transition to the lowest energy state—a BEC—when they come close enough to one another and move slowly enough.A group of physicists from the University of Maryland and the National Institute of . Bose-Einstein condensate (BEC), a cloud of atoms cooled to temperatures very close to absolute zero in which all the atoms are in the same quantum state, can replicate the expansion of the early Universe.Although they are not naturally occurring on Earth, some people theorize that BEC-like gases may form due to the high pressure surrounding neutron stars (1). Particles may become extremely close to one another at high densities in that harsh environment, acting like condensates.A BEC is created by rapidly cooling a gas with an incredibly low density—about 100,000 times that of ordinary air—to extremely low temperatures. Generally speaking, Satyendra Nath Bose and Albert Einstein made the first predictions about this state in 1924–1925. A Bose Einstein condensate can be found in many well-known situations.

What is a good illustration of the fifth state of matter?

Bose-Einstein condensates (BECs), which were first made in a lab 25 years ago, are a fifth state of matter that exists as well. When a collection of atoms is cooled to almost absolute zero, they start to clump together and act like one giant super-atom. Along with solids, liquids, gases, and plasmas, Bose-Einstein condensates are sometimes referred to as the fifth state of matter. Bose-Einstein condensates, or BECs, were theorized in the early 20th century but weren’t actually made in a lab until 1995.The five states of matter are Bose-Einstein condensate, solid, liquid, gas, and liquid at high temperatures.When the right circumstances are met, even multiple fermions, which ordinarily cannot occupy the same quantum state, can reach a state known as a Fermionic condensate, where they all achieve the lowest-energy configuration possible. The seventh state of matter is this one.Bose-Einstein Condensation of Photons Bosons have a tendency to group together and, under certain conditions, can condense into a massive wave known as a BEC.
