Is glass considered a liquid in scientific terms?

Answer 1

Glass is typically made by silicates fusing with boric oxide, aluminum oxide, or phosphorus pentoxide, it is generally hard, brittle, and transparent or translucent, and is considered to be a supercooled liquid rather than a true solid.

Answer 2

No, glass is no liquid. Some people believe this because of the molecular structure of glass, and the fact that very very old windows are thicker at the bottom.

Glass is an interesting substance because it has the properties of a solid, but the molecular structure of a liquid. In most solids, the molecules line up and bond in a crystal lattice, giving the solid its solidity and strength. Glass has that of a liquid, having all the molecules jumbled around in a mess, without lining up or crystalising. Regardless, it has a definite volume and a definite shape, and therefore is a solid. Because of it's molecules, it's a special type of solid, an amorphous solid.

And the reason old windows were thicker at the bottom is because of the vast improvements in window making, that has led to uniformly thick windows. Way back then, they just couldn't make them very well.

Hope this helps.

Answer 3

Yes.. an Indian scientist have discovered that electricity can pass through glass. In a sense, it can be considered a liquid in scientific term... do u think so???? I think glass can be considered as liquid based on the above.

Answer 4

"One common misconception is that glass is a super-cooled liquid of practically infinite viscosity at room temperature and as such flows, though very slowly, similar to pitch. Glass is generally treated as an amorphous solid rather than a liquid, though different views can be justified since characterizing glass as either 'solid' or 'liquid' is not an entirely straightforward matter [1]. However, the notion that glass flows to an appreciable extent over extended periods of time is not supported by empirical evidence or theoretical analysis."

Answer 5

What does liquid mean, or more precisely, fluid. What does "fluid" mean, so you can tell if glass is a liquid.

A fluid is a material that under a constant shear load exhibits constant rate of deformation. Its not like a rubber eraser, where it deforms then stops, but it continuously deforms.

Glass, when its very hot, is certainly a liquid.
Glass at room temperature, is amorphous in structure, but its failure modes and deformation rates are not consistent with a fluid. Yes there can be creep, but creep can exist is solid, fully crystalline metalic solids as well.

My "scientific" concusion, is that glass although structurally amorphous, its not a fluid because it doesnt have constant deformation rate when under a constant shear.

Answer 6

No....it is what is called an amorphous solid. That is, it has no long-range order of the positions of the atoms, as opposed to crystalline solids.

A liquid is one of three main phases of matter. It is a fluid whose shape is determined by the container it fills; its particles (molecules or molecular clusters) are free to move within the liquid volume, but their mutual attraction limits the ability of the particles to leave the volume.

Answer 7

Yes, it's considered a super-cooled liquid.

Answer 8

uh huh

Answer 9

amphorous liquid actually.

Answer 10

yes, at any tempreture even
