The NASA (National Aeronautics and Space Administration) scientists in the International Space Station unveiled the first results of Bose-Einstein condensate experiments under which the particles can be manipulated free from Earthly constraints.
Bose-Einstein Condensates
- Bose-Einstein Condensates were predicted by Indian Mathematician Satyendra Nath Bose and Albert Einstein almost a century ago.
- The BEC is a state of matter that is typically formed when a gas of bosons is cooled to temperatures close to absolute zero.
- Absolute Zero is the temperature at which the entropy and enthalpy of cooled gas reach their minimum value.
Four States of Matter
- There are four state of matter namely solid, liquid, gas and plasma.
- The fourth state of matter called the plasma was described by the chemist Irving Langmuir.
- It consists of gas of ions in which orbital electrons are removed and positively charged nuclei roam freely.
Fifth State of Matter
- The BEC is the fifth state of matter and was created by the scientists 25 years ago.
- When a group of atoms are cooled to absolute zero, the atoms clump together behaving as a one big super atom.
- This state is called the fifth state of matter and is referred to BEC.
