What is BEC state of matter?

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 the 5th state of matter called?

Bose-Einstein condensates
There are four states of matter common in everyday life — gases, liquids, solids, and plasmas. However, there is also a fifth state of matter — Bose-Einstein condensates (BECs), which scientists first created in the lab 25 years ago.

Why is bec a state of matter?

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. Instead, the atoms fall into the same quantum states, and can’t be distinguished from one another.

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.

How is BEC formed?

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 4th and 5th state of matter?

There are four natural states of matter: Solids, liquids, gases and plasma. The fifth state is the man-made Bose-Einstein condensates.

What is the 5th state of matter used for?

In quantum mechanics, the Bose-Einstein condensate is used to conduct quantum experiments. In 1995, researchers were able to prove that a fifth state of matter — the Bose-Einstein condensate — could be created at very low temperatures.

What is the 5 types of matter?

The five phases of matter. There are four natural states of matter: Solids, liquids, gases and plasma. The fifth state is the man-made Bose-Einstein condensates. In a solid, particles are packed tightly together so they don’t move much.

What is the third state of matter?

The three states of matter are the three distinct physical forms that matter can take in most environments: solid, liquid, and gas. In extreme environments, other states may be present, such as plasma, Bose-Einstein condensates, and neutron stars.

What plasma means?

Plasma is the largest part of your blood. When separated from the rest of the blood, plasma is a light yellow liquid. Plasma carries water, salts and enzymes. The main role of plasma is to take nutrients, hormones, and proteins to the parts of the body that need it. Cells also put their waste products into the plasma.

What is Bec in condensed matter physics?

In condensed matter physics, a Bose–Einstein condensate (BEC) is a state of matter (also called the fifth state of matter) which 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 the Bose-Einstein condensate (BEC)?

NASA scientists on Earth have collaborated with astronauts on the International Space Station (ISS) to corral the first ever Bose-Einstein condensate (BEC) outside of Earth’s gravity. Among other things, the BEC lasted hundreds of times longer than the same substance on Earth’s surface.

What is a BEC used for?

A BEC is used to study quantum mechanics on a macroscopic level. Light appears to slow down as it passes through a BEC, allowing scientists to study the particle/wave paradox. A BEC also has many of the properties of a superfluid, or a fluid that flows without friction. BECs are also used to simulate conditions that might exist in black holes.
