I only knew about three states of matter.

Solid, Liquid and Gas – These are what the good school teachers talk about.

Then came along Plasma. It is basically an ionised gas that is highly conductive and allows us to watch football on huge Plasma TVs.

I was told by a friend that these four can be ranked in terms of the amount of energy that they carry.

Solid -> Liquid -> Gas -> Plasma

What is the fifth?

It’s the Bose-Einstein condensate. You will only get it when you cool atoms to absolute zero, so you will see this fifth state of matter when you put all your exes’ cold hearts together.

So in summary:

1. Solid
2. Liquid
3. Gas
4. Plasma
5. Bose-Einstein condensate

Not sure if this knowledge will really matter.
