Question

What type of state is glass? please explain about it.

Answer 1

I think the other answer is incorrect. Glass being a liquid is a misconception, from when glassmaking was imperfect and windows were thicker at the bottom of the pane than the middle. But that was from when the glass was MADE, after being heated and put into a liquid form.

Answer 2

On a small time scale, glass is in a solid state. When you look at a window, it appears solid.

However, it has been observed that over a very long period, glass starts to act like a liquid.

It can thus be characterized by two different states depending on the time scale considered.
