Plasma: The state consists of super energetic and super excited particles. These particles
are in the form of ionised gases. The fluorescent tube and neon sign bulbs consist of
plasma. Inside a neon sign bulb there is neon gas and inside a fluorescent tube there
is helium gas or some other gas. The gas gets ionised, that is, gets charged when
electrical energy flows through it. This charging up creates a plasma glowing inside
the tube or bulb. The plasma glows with a special colour depending on the nature of
gas. The Sun and the stars glow because of the presence of plasma in them. The plasma
is created in stars because of very high temperature.
Bose-Einstein Condensate: In 1920, Indian physicist Satyendra Nath Bose had done
some calculations for a fifth state of matter. Building on his calculations, Albert Einstein
predicted a new state of matter – the Bose-Einstein
Condensate (BEC). In 2001, Eric A. Cornell, Wolfgang
Ketterle and Carl E. Wieman of USA received the Nobel
prize in physics for achieving “Bose-Einstein
condensation”. The BEC is formed by cooling a gas of
extremely low density, about one-hundred-thousandth
the density of normal air, to super low temperatures.
