How many states of matter are there one two three or four?

Answer 1

I know of 7 states of matter, although of those, there are only 4 that you would be likely to encounter here on Earth. The common phases of matter are solid, liquid, gas, and plasma. The more unusual phases are degenerate matter (found in neutron stars) and Bose-Einstein condensates (found in the laboratory only), and the super-fluid phase of liquid helium, also found only in the laboratory.
