Solids, Liquids And Gases

PLASMA : 
    
Plasma is the fourth state of matter.
Plasma is an ionised gas, a gas to which sufficient energy is provided to get free electrons from atoms or molecules to allow both the species, ions and electrons to co-exist. It exists in the presence of high temperature 
Ex:  The gases in the sun and stars exist in plasma state.

BOSE-EINSTEIN CONDENSATE: 
It is the fifth state of matter. 
Bose-Einstein condensate is a super fluid phase formed by atoms, cooled very near to absolute zero temperature. It is opposite to plasma state as it occurs at very low temperature.
Ex:  First condensate was produced by Rubidium  atoms (Rb) cooling to 170 nanokelvin.
