  5. Plasma forms at extremely high temperatures, where thermal energy overcomes atomic bonds.
  6. Examples of plasma include the Sun, stars, lightning, and neon signs.
  7. Bose-Einstein condensate forms at temperatures close to absolute zero (0 Kelvin or -273.15°C).
  8. The BEC state occurs when particles known as bosons occupy the same quantum state, behaving as a single entity.
  9. The concept of BEC was predicted by Albert Einstein and Satyendra Nath Bose in the 1920s.
  10. Plasma is considered the most abundant state of matter in the universe, making up 99% of visible matter.
  11. Plasma conducts electricity due to the presence of free-moving charged particles.
  12. The study of plasma is essential in fields like astrophysics, nuclear fusion, and plasma technology.
  13. In plasma, magnetic fields significantly influence the motion of charged particles.

  19. The temperature of plasma can range from a few thousand to several million Kelvin.
  20. Quark-gluon plasma, an exotic type of plasma, existed moments after the Big Bang.
  21. BEC represents a macroscopic quantum phenomenon where quantum effects are visible on a large scale.
  22. Plasma is used in various technologies like plasma cutting, semiconductor manufacturing, and fusion reactors.
  23. Plasma is often referred to as an electrically neutral state, despite the presence of charges, because the number of positive and negative charges is nearly equal.
  24. The cooling of atoms to create BEC involves reducing their energy to an almost motionless state.
  25. Unlike plasma, which requires high energy, BEC forms under extremely low energy conditions.
  26. Plasma displays unique properties like plasma oscillations, waves, and instabilities.
  27. Plasma often interacts with electromagnetic fields, making it vital for studying space weather and solar winds.
