Reply to comment by jmukes97 in ELI5- what is the difference between a liquid and a fluid? by stinkybuttttt

 amorphous solid is a liquid that does not flow: its atomic structure is disordered like that of a liquid but it is rigid and holds its shape like a solid. Amorphous materials include silica glass and a multitude of other materials of different origins, such as soft glasses (like concentrated emulsions, mousses and colloidal glasses)

dude, you keep linking the same incorrect definition over and over again. whats more, its literally the only source i can find that calls amorphous solids liquids on the entire internet. every single other website correctly calls them solids and you chose to run with the single incorrect one.

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?
