Is glass technicly a solid or a liquid?

Question

Most of you take the obvious answer yes BUT i only want people who know the right answer to give an answer because believe it or not glass doesnt have a definate shape and is considured to many the slowest moving liquid, if you have windows that are decades old feel both sides of the top with both ands and move your way down, it will get fatter as you go down meaning it flowed down over time. But ive heard that a liquid also has to flow at a certain pace in order to be a liquid. If you didnt know glass didnt have a permanent definate shape that could change with no interferance then you just learned somthing from a person asking you a question :)

Answer 1

I blow molten glass from a furnace.
Glass is an amorphous solid at room temperature. Unfortunately, some people use "like a liquid" to describe amorphous.
Glass is solid enough at 900F that it will shatter when dropped on a hard service.
Glass does NOT change shape with time as can be shown with 1500 year old Roman glass that is still in good shape.
Glass does not slump in windows. Until about 1880 glass was made by spinning a disk of glass that was thinner at the edge than the middle which was cut into panes. This glass looked best when the thick edge was at the bottom instead of any other side or just placed randomly.
Glass is NOT a supercooled liquid - a super cooled liquid is one that is still liquid but below its freezing point - adding a crystal will cause the whole batch to freeze to solid almost instantly.

Answer 2

First of all, you must understand what solid or liquid means. Solid is any materials that has a DEFINITE volume and DEFINITE shape.
Liquid is any materials that has NO DEFINITE SHAPE, but DEFINITE volume. Also, liquids take up all the space and will take shape of the container.

Since liquids take the shape of their containers, glass doesn't. Glass once once sand and quartz, and so when sand and quartz is heated, it changes into glass. Therefore the windows ant our homes are solid, but can also be called as super hard liquid. Glass is considered as an amorphous solid.

Also, if glass is not heated, it will not melt or become liquid. If you have ever tried to keep glass in a dark room, it would become thicker at the bottom at all. Since glass is heated, some parts contract or expand, or otherwise, it will not be melted unless the temperature is very very high.

Answer 3

stable question. In a "0-gravity" surroundings, in case you spurt drops of water into the air, the water droplets will stay stay jointly and glide around like little sphere. Why is this? Its because of the fact there is no aparrent stress (gravity, atmospheric stress) present. in case you are attempting this in the international, the water will drop to the floor and pass. All supplies ("solids, gases, beverages") are difficulty to to flowing interior the presence of a stress, some supplies require a plenty greater beneficial stress than others until you could locate a reaction although. look at chocolate, if its in a candy bar, its sturdy. once you place some stress on it, it's going to finally soften and pass. contained related to glass, gravity and atmospheric stress are performing upon it. The stress is making the glass reorder and circulate to a decrease thermodynamic state. So in essence, its a sturdy that flows (very slowly) or a surprisingly viscous liquid (which has been reported formerly), its all semantics.

Answer 4

Solids are of two types; polyhedral crystals and amorphous crystals.

Amorphous means without form. Amorphous SOLIDS are antitheses (contrast) of regular polyhedral crystals.

Regular polyhedral crystals are combinations of crystals. Crystals have definite shape. However polyhedral crystals though made of crystals are not regular. Still they are not amorphous.

Most bodies commonly encountered, particularly metals and rocks are polycrystalline sunstances.

Crystalline bodies are recognized by their well defined melting points. If heat is applied to a crystalline body, the temperature of the body increases until it begins to melt. Thereupon, the temperature ceases to rise and the entire melting process takes place at the melting point.

Ordinary glass is a typical amorphous SOLID. It goes soft when it is heated and gradually goes over into the LIQUID state as the temperature is raised.

The behaviors of amorphous bodies can be explained by their structural peculiarities, leading to the classification of such bodies as liquids rather than solids. However this does not imply that glass is liquid. Glass is viewed as a damaged crystal.

Many liquids harden before they become very viscous. The high viscosity of glue, honey, tar and oil is due to the complex form their molecules. These liquids can be classified as solids because of this viscous property. Yet they are not considered as solids.

Answer 5

"Technically," liquid vs. solid is not a very useful distinction. Is Jello a liquid or a solid? Is sand? Is sugar dissolved in water? Liquid, solid, and gas are used as qualitative labels only, without any real technical definitions. Over short timescales, glass is a solid because you can use equations of solids (like stress/strain) to describe its behavior. Over long timescales, glass is a liquid because you can use fluid equations to describe it. Same with magma, jello, and water.

"The Three Phases of Matter" is a clumsy kludge that we teach high schoolers to illustrate the concepts of phase change. But in reality, every material has its own individual properties. Some materials are more solid-like, and others are more liquid-like perhaps.

Answer 6

Way back in highshool, i was taught that glass is liquid and yes I have done the test with decades old glass but I have no idea wether a liquid must have a specific rate of flow to be a liquid

Answer 7

i thing glass is not a solid and not a liquid because it has not have any definite shape but instead of it ;it is in between solids and liquids

Answer 8

you cant consider glass as a liquid. there are exceptions.like a sponge when you compress it changes its shape. similarly glass is also a exception.to know more about glass read the information given in the following site:-

Answer 9

glass is clasified as a super cooled liquid. it will get thicker at the bottom over time.
glass in sloid state is called sand.

Answer 10

glass is made from sad when you heat the San withe the torch it malt an terns to a glass after it cools off
