Which of the following states of matter is formed by cooling a gas of extremely low density, about one-hundred-thousandth the density of normal air, to super low temperatures? Correct Answer Bose- Einstein condensate

Concept:

States of Matter: There are five states of matter.

  1. Solid
  2. Liquid
  3. Gas
  4. Plasma
  5. Bose-Eienstein Condensate(BEC)

Bose-Einstein Condensate(BEC): 

  • Gases at extremely low density are cooled to extremely low-temperature therefore, atoms are unable to move at all and collapsed into a single quantum state. As atoms become indistinguishable they behave as a super-atom. They are super-fluids and super-conductors. Example: Helium below temperature 2.17 K.

Plasma state:

It is a mixture of free electrons and ions.

  • The state is consists of super excited and super energetic particles that are present in form of ionized gases.
  • Plasma is made by heating a gas to a very high temperature so that gas molecules lose all their electrons.
  • It does not have a definite shape and volume.
  • Example: This state is mostly observed in stars.

Additional Information

  • Solid: Particles of matter are bounded very tightly so that it has very low kinetic energy (almost negligible) that's why it has a definite shape and volume and cannot be compressed. Example: Iron sheet, aluminium foil.
  • Liquid: Particles of matter are bounded loosely so that it has low kinetic energy. The particles can move freely and randomly throughout liquid but do not break the boundaries. It has a definite volume and cannot be compressed. Example: milk, water. 
  • Gas: particles are not bounded so that it has high kinetic energy. The particles can move freely and randomly anywhere. It does not have a definite shape and volume. It is highly compressible.  Example: Water vapour, oxygen, hydrogen.
