Is glass a solid or a liquid?

Answer 1

The glass can be considered as been vitreo. The great difference between glasses and the other materials is high viscosity above of the fusing point. It is characterized by a physical solid behavior with liquid structure, that is, it is a intermediario point between I eliminate it and the solido one and does not possess symmetry. Its moleculas does not hold as I eliminate, that relatively they are joined and nor as solidos that extremely they are joined.

Answer 2

MYTH ALERT!

Yes, glass is an amorphous solid, which, like many plastics, displays properties of solids and liquids.

However, looking at 100 year old windows is NOT a good way to see this. At room temperature, glass does not flow appreciably over any period of time that humanity would notice. The reason that old windows are thicker at the bottom is....

POOR QUALITY CONTROL 100 YEARS AGO. When window glass was being made at this time, it was always somewhat uneven. So, how would you put the glass into the frame? That's right--with the thicker, heavier, stronger edge toward the bottom. The glass is still in that orientation today, because nobody has moved it.

Answer 3

"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.

Nevertheless, from a more common sense point of view, glass should be considered a solid since it is rigid according to every day 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."

Answer 4

Glass is an amorphous solid. It possesses properties of both solids and liquids. The best way to consider glass is having a solid exterior that surrounds a liquid interior. You can see the liquid property of (room temperature) glass by looking at windows in older homes. The glass has shifted to the bottom due to gravity.

Answer 5

Yes...

Glass is a slow moving liquid...very slow moving.
If you go to an old house (100 years or older) and look at the original windows, you will notice that they are thicker at the bottom. Over time, the "liquid" glass has succumbed to gravity.

(Just as a side note: now that I have type "liquid" a couple of times, what a dumb word it is! It sounds funny and is spelled weird!)

Answer 6

Solid. Liquid has no definite shape! Glass does.

Answer 7

Believe it or not it is a liquid. If you look at windows in an old house, the windows are thicker at the bottom than at the top. THat's because the glass is liquid and eventually flows toward the bottom.

Answer 8

it's both, folks! glass is actually an amorphous solid, which means it is a solid, but its molecules do move past each other, like a liquid. given enough time, any vertical pane of glass will eventually flow downwards and no longer be in its original shape (such as a window).

Answer 9

Glass is a liquid, however very slow moving. Look at centuries-old stained glass windows and see how the glass is thicker at the bottom.

Answer 10

Glass is a supercooled liquid. Look at windows on old buildings. The glass actually runs very very slow.
