The number of states of matter commonly known and taught in a general science context is considered to be 5.

The three classical states of matter are Solid, Liquid, and Gas. Beyond these, Plasma is widely recognized as a fourth state, and the Bose-Einstein Condensate (BEC) is considered a fifth state.

Plasma is an ionized gas existing at high temperatures. BEC is formed at temperatures near absolute zero. Other states of matter exist under extreme conditions (e.g., neutron-degenerate matter), but 5 is the most common answer when these options are presented.
