Expert Answer:

 The fourth state is Plasma: The state consists of super energetic and super excited particles. Theseparticles 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.

The fifith state is 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.
