Re: What are the five states of matter?

When I was a boy, there were three states of matter.

Solid
Liquid
Gas

Then people came up with a fourth state, called plasma.  This state
occurs at very high temperature, when all molecules break up into atoms,
and the atoms become ionized.

Recently, scientists have discovered the Bose-Einstein condensate, which
can be thought of as the opposite of a plasma.  It occurs at ultra-low
temperature, close to the point that the atoms are not moving at all.
This is being called the 5th state of matter.
