what is glass, a solid or a liquid?

Answer 1

Glass is a liquid, but after it cools off it's a solid. Have you ever watched a glass blower?

Answer 2

Glass is technically a liquid. My hobby is creating panels in stained glass. If you score a piece of glass but don't break if fo a long while, the score will become less deep and will be unable to snap the glass.

Another proof of glass being a liquid is to look at windows in very old buildings. If the window is a large sheet of glass, over many many years, you can see the ripples flowing downward.

BUT - for most purposes, glass behaves like a solid and should be considered a solid in use.

Answer 3

I guess that really depends on how you view things, at what level? Although the molecular structure of "glass" is not truly static, for all intents and purposes, glass is a solid. At particular tempuratures, glass does become molten and liquid, at even higher temperatures in an inert atmosphere, it could even vaporize as a gas.

The state or phase of any substance is defined as solid, liquid or gaseous. Theoretically, only at tempuratures of absolute zero, or -273 degrees Centigrade, would all things be solid. Substances that reach particular tempuratures undergo a rapid physical change or phase into another state. Water is a solid from -273 degrees C to 0 degrees C to become a liquid and then a gas [not quite] at 100 degrees C. The reason I say, "not quite" is because in our atmosphere, water in a gaseous state generally corrodes or combines with other substances so that it is no longer H2O. Even liquid water is a relatively universal solvent that does not remain just water or remain in a pure state. It dissolves minerals and other matter to become a liquid solution of varying dilutions of new compounds.

Anyway, glass as we know it, is a solid.

Answer 4

LOL - I am a chemist and was in a debate about this a couple of years ago. I called a rather large glassware vendor and spoke to the president - he stated that glass is a super cooled liquid, but behaves like neither a liquid nor solid completely. Thats what I learned in school as well.

Answer 5

Liquid

Answer 6

A liquid turned solid i suppose

Answer 7

Glass is a Solid.

Answer 8

liquid.............if you look at a very old window you will see that the glass is thicker at the bottom than at the top. That's because the liquid glass which is very viscous has flowed slowly to the bottom.

Answer 9

it's an amorphous solid as in the molecular state it is still closer to liquid. Made of silica fused with phosphates and borates

Answer 10

Glass is a highly viscus liquid.
If we look to old window : the thickness at the top is smaller than that of the end.
this mean that the glass is flows from the top to the end of the window
