What is the example of Bose-Einstein condensate?
Two examples of materials containing Bose-Einstein condensates are superconductors and superfluids. Superconductors conduct electricity with virtually zero electrical resistance: Once a current is started, it flows indefinitely. The liquid in a superfluid also flows forever. In effect, there is no friction.
Where is BEC used?
One application for BEC is for the building of so-called atom lasers, which could have applications ranging from atomic-scale lithography to measurement and detection of gravitational fields.
What is BEC in simple words?
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 BEC in Chemistry for 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. It is found at low temperatures when particles are not incapable of moving.
What is plasma and BEC?
The key difference between plasma and Bose Einstein condensate is that plasma state contains a gas of ions and free electrons whereas Bose-Einstein condensate contains a gas of bosons at low densities which is cooled to a low temperature close to absolute zero.
How is BEC formed Class 9?
A BEC is formed by cooling a gas of extremely low density (about 100,000 times less dense than normal air) to ultra-low temperatures.
What is bec and plasma give example?
They are considered as the fifth states of matter after the plasma. They are a group of atoms cooled to within a hair of absolute zero. For example, we can take Helium. BEC when reached near to temperature zero the atoms are hardly moving relative to each other since they have very less free energy to do so.
What is plasma and BEC class 9?
Plasma and BEC (Bose-Einstein Condensate) are considered as states of matter other than solid, liquid and gas. These are known as fourth and fifth states of matter. Plasma: It is considered as the fourth state of matter. Particles of plasma are made of free electrons and ions.

Which is an example of a BEC attack?
BEC is essentially an attack where the cyber attacker accesses corporate email accounts and spoofs the owner’s identity. From there, emails are then sent to employees and customers of the company in an effort to steal money and other assets. Here are five examples of BEC scams in the wild. 1. Xoom Corporation
What does Bec mean for a business email?
BEC scams involves the compromise of legitimate business and e-mail accounts for the purpose of conducting unauthorized wire transfers. A guide providing best practices on what to do to safeguard the email system of a business from being compromised.
Can a business be a victim of Bec?
FBI Chicago has important information for area business owners who find themselves the victim of a Business E-mail Compromise (BEC) scam. The organized crime groups that perpetrate the financial cyber fraud called business e-mail compromise have victimized companies and organizations around the world.
Is the number of Bec’s on the rise?
BEC rates have been rising for several years, as demonstrated by 2021 data from the FBI’s Internet Crime Complaint Center (IC3). The IC3 says that in 2020, losses from BEC exceeded $1.8 billion—that’s a fourfold increase since 2016. The number of BEC incidents also rose by 61% between 2016 and 2020.
