Glass: Liquid or solid?

Now this is a lil more complicated than those noob questions about solid and liquids.

liquid

but it has a definite shape and volume

[redrumracer]

i mean it has a disorderly molecule arrangement like a liquid but the rigidity of a solid

There is no clear answer to the question "Is glass solid or liquid?". In terms of molecular dynamics and thermodynamics it is possible to justify various different views that it is a highly viscous liquid, an amorphous solid, or simply that glass is another state of matter which is neither liquid nor solid. The difference is semantic. In terms of its material properties we can do little better. There is no clear definition of the distinction between solids and highly viscous liquids. All such phases or states of matter are idealisations of real material properties. Nevertheless, from a more common sense point of view, glass should be considered a solid since it is rigid according to everyday experience. The use of the term "supercooled liquid" to describe glass still persists, but is considered by many to be an unfortunate misnomer that should be avoided. In any case, claims that glass panes in old windows have deformed due to glass flow have never been substantiated. Examples of Roman glassware and calculations based on measurements of glass visco-properties indicate that these claims cannot be true. The observed features are more easily explained as a result of the imperfect methods used to make glass window panes before the float glass process was invented.

Glass is an amorphous solid, blame the German's for the misconception of it being a liquid.

god damnit, go figure im German.

Damn Germans.

It is solid. The reason why it is usually found to be thicker at the bottom of old glass windows (and why people say it is liquid) is that glassmakers couldn't make a perfectly uniform piece of glass. When you want something to sit upright that isn't uniform weight, what do you do? You put the heaviest end at the bottom.

man, wtf is all the questions of what is a solid or liquid.

i think IA needs to add another subforum for this shit.
