What are the 7 states of matter?
There is currently thought to be 7 states of matter although we only really observe 3 of them in everyday life.....
Solids, liquid and gas (the ones we all are familiar with).
Then also ionised plasmas, Bose-Einstein condensate, Fermionic condensate, and Quark-Gluon plasma. These only exist under very specific conditions that are unlikely to occur in everyday observations (e.g. very low temperature, and with specific types of atoms and particles).
