Is glass really a liquid?

Question

Is glass really a liquid?

Answer 1

yea... it's a slow moving liquid

Answer 2

My teacher last year told me it was, apparently because you know when they uncover like really old bottles, they have a kind of droplet running down very very very slowly, well you cant see it moving but sometimes they have like a bit dripping down - thats why apparently but my bro says its a solid.  

Answer 3

No. Glass is an amorphous solid.

An amorphous solid is a solid in which there is no long-range order of the positions of the atoms. For instance, common window glass is an amorphous ceramic. Other amorphous solids include plastics and resins.

Glass displays all the mechanical properties of a solid. The notion that glass flows to an appreciable extent over extended periods of time is not supported by empirical research or theoretical analysis. From a more commonsense point of view, glass should be considered a solid since it is rigid according to everyday experience.

The antique glass is thicker at the bottom purely because of the method of producing glass in those times. It HASN'T flown downwards like some slow liquid. It's a myth.

Answer 4

Glass is sand

Answer 5

Yes. In fact, if you measured really, really old windows the glass at the bottom of the pane is thicker than at the top. It has very slowly run down.

Answer 6

All elements can change to 4 states of matter:

Solid

liquid

gas

Plasma ( super heated gas)

These states depend on the boiling and melting points of the element or compound. Now glass is a compound of silicon and oxygen SiO2 and it heats together to for glass. This is an irreversible reaction. Then if you cool it down it turns to glass. Heat it up and it turns to a molten glass.

Answer 7

Yes, it is, just a very solid, slow moving one.

If you look at really old windows, they will often be thinner at the top, and thicker at the base as the glass moves down very slowly over time.

Strange but true.

Answer 8

when its melted yeah....

Answer 9

Glass is a solid that can be turned into a gloppy, lava-like liquid when heated to extreme temperatures!

Answer 10

Yes.  

When melted at a certain degree it becomes a liquid.  You have heard of blown glass, haven't you.  That is when the glass is melted and blown like bubble gum into a beautiful shape, then hardened.

Look it up online:

Any of a large class of materials with highly variable mechanical and optical properties that solidify from the molten state without crystallization, are typically made by silicates fusing with boric oxide, aluminum oxide, or phosphorus pentoxide, are generally hard, brittle, and transparent or translucent, and are considered to be supercooled liquids rather than true solids.

Answer 11

When you heat glass, it gets transformed into molten form. Then, you can again give it any shape. At room temperature, it's always solid

Answer 12

Yes, but it's really viscous (thick). It's why in construction they have limits on how big they are able to make panes of glass, because then it may start to become more obvious when it sags!!

Answer 13

straight up, if u go chek out old churches in europe ull notice the bottoms of the windows are thicker than the top cos its still a liquid and the glass has been sliding down

Answer 14

Is glass liquid or solid?

here's the long answer.

Answer 15

It is solid but not crystalline. Solid glass has some properties of a liquid, e.g. the glass in very old windows is thicker at the bottom than at the top because it flows down, although very slowly  

Answer 16

Yes, you can go to a glass factory to see it being made.

Answer 17

No. It's a solid. The statement that it's a liquid is due to misunderstanding of the science of glassmaking - and the so-called evidence of older glass is just misleading.

Answer 18

yes

Answer 19

No.
