That's admittedly a common misconception, but glass is an amorphous solid. It's not a liquid in any sense of the term, even though the atomic structure resembles a super-cooled liquid.

Amorphous means it changes.

Definition.

An 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.Jul 7, 2008

That's the same misconception.

"Amorphous solid" means that it lacks the long-range order characteristic of crystalline material. It resembles a liquid, but it is not a liquid.

W.e man. I litteraly linked the definition of amorphous solid.

You did, and you're still wrong.

An amorphous solid can be described like a liquid, but that doesn't mean it is one. An amorphous solid does not flow; it does not assume the shape of its container.

It is not a liquid.

An amorphous material has a liquid atomic structure but does not flow as a fluid.

That is the litteral definition of amorphous materials.

They are classified as a solid liquid or non fluid liquid.

They're solids. An amorphous solid is a solid.

That has the atomic makeup of liquid structure. A non crystalline lattice.

But it's still a solid.

>In condensed matter physics and materials science, an amorphous solid (or non-crystalline solid) is a solid that lacks the long-range order that is characteristic of a crystal. The terms "glass" and "glassy solid" are sometimes used synonymously with amorphous solid; however, these terms refer specifically to amorphous materials that undergo a glass transition. Examples of amorphous solids include glasses, metallic glasses, and certain types of plastics and polymers.


>An amorphous metal (also known as metallic glass, glassy metal, or shiny metal) is a solid metallic material, usually an alloy, with disordered atomic-scale structure. Most metals are crystalline in their solid state, which means they have a highly ordered arrangement of atoms. Amorphous metals are non-crystalline, and have a glass-like structure.

Science named it amorphous solids.

In the most basic sense it's a solid liquid. But that's not conducive to the model so they named it amorphous solid.

It's a solid that is atomicly a liquid or should be according to the standard model of physics. But it's not. So it's an amorphous solid.

It's not a liquid at all, my dude. It's a solid that has short-range order, but not long-range order.

It fits no other properties of a liquid.

But he found a single paper from 2008 that, if read a certain way, supports his view! He must be right!

Physicist here. Amorphous doesn't mean it changes. Amorphous means "it has no long-range order". As opposed to crystalline solids, where this longe-range translational symmetry is present.

Glass is an amorphous solid. It's not a liquid. It has a structure somewhat similar to a liquid, but calling it "a liquid which doesn't flow" is like calling a tank "an aeroplane that doesn't fly".

No, it doesn't. It means it has non crystalline structure.
