Reply to comment by Shifter93 in ELI5- what is the difference between a liquid and a fluid? by stinkybuttttt

Yes a SOLID liquid.

amorphous solid, any noncrystalline solid in which the atoms and molecules are not organized in a definite lattice pattern.

Like a liquid.

"like a liquid" does not equal a liquid. its a solid. not a "solid liquid", which isnt a thing, and its not a liquid.

all liquids flow. every single one of them. it is an intrinsic property of liquid. its literally impossible for a liquid not to flow because flowing is a requirement of being a liquid. if something does not flow, then it can not be called a liquid. the fact that amorphous solids do not flow is exactly what makes them not a liquid, because again, all liquids flow.

No, an amorphous solid is not a liquid.

A liquid is: “a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure” (from Wikipedia).

An amorphous solid does not flow to conform to the shape of it’s container. Thus, and amorphous solid is not a liquid.

Further, many solids are non crystalline. Wood for example. Also charcoal. Also paper.

Are you seriously planning to argue that paper is a liquid?
