Reply to comment by WinBarr86 in ELI5- what is the difference between a liquid and a fluid? by stinkybuttttt

It is similar to both liquid and solid. If we were sticking to the big 4, it would reasonably be a solid. If we are allowing an expansion of the defined states, it would be a separate state that is neither liquid nor solid.

Edit: Note that in the article they keep switching between calling them 'solids that behave like liquids' and 'liquids that behave like solids'. Suggesting that neither category is really applicable.

There are way more than 4 states of mater.

Schools teach the wrong shit to keep it super simple. There are 7 states of matter that I'm aware of.

I will die on this hill.

Not all fluids are liquid and not all liquids are fluid. You have non newtonian fluids that are not liquids and you have amorphous solids that have the make up of liquids but are not fluid.

Amorphous solids are not liquid. They are amorphous solid. They have properties of both solids and liquids, but they are neither.

There are far more than 7 states, and it is pretty likely that any list you or I or an expert in the field could come up with would be incomplete 20 years from now.

You are dying on the hill of 'There are more than four states of matter, but we must place everything in one of those states'

Amorphous solids are solids that have an atomic makeup closer to a liquid.
