is glass a liquid?

im not asking because i want to have someone explain it to me (i already know the answer). this is simply a matter of discovering what most people think.

Glass is a solid. When heated it is in liquid form.


Just like an ice cube is a solid, and a liquid in water form.

Doesn't matter because he's wrong anyway. 😛
 
It's a solid. I know I have heard how solid glass "flows" very very slowly, but it's still a solid, true "liquid" glass only occurs when it heat it up greatly.

Well... I've explained it to others as well who may not have been able to grasp the complexity of the question at hand.

Glass doesn't flow. It's a myth.
 
I haven't ever looked it up for myself, but I remember years ago one of my friends telling me something about glass being an extremely slow moving liquid or something/ Like glass thinks it's better than other liquids! It's like "Oh, I'm glass. I'm a liquid but I'm gonna act like a solid. In fact, I'm even gonna HOLD other liquids, HA! Take that liquids."

That damn arrogant glass.
 
It's a solid. The idea of a "supercooled liquid" or super-high viscous liquid is a semantic misnomer, as in nature there is no clear distinction between solids and highly viscous liquids.
 
One arguably justifiable belief is that glass is a 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 [3]. However, the notion that glass flows to an appreciable extent over extended periods of time is not supported by empirical evidence or theoretical analysis.

A myth does exist that glass rods and tubes can bend under their own weight over time. To check it, in the 1920s, Robert John Rayleigh, son of the Nobel Prize winner John William Rayleigh, conducted an experiment on a 1 metre (~39 in) long, 5 millimetre (~3/16 in) thick glass rod, which was supported horizontally on two pins with a 300 gram (~0.66 lb) weight in the middle. Apart from the initial bending of 28 millimetre (~1.1 in), the position of the weight did not change until the end of the experiment, which lasted for 7 years. At the same time, another man, a worker of General Electric named K. D. Spenser, conducted a similar experiment independently. Two months after Rayleigh, he published his own results which also disproved the myth. Spenser suggested that the myth was composed before the 1920s, when the tubes were made by hand, and naturally some of them were curved to begin with. Over time the straight tubes were taken away, and only the curved ones remained. Some people probably thought it was the glass flowing.

There is no clear answer to the question "Is glass solid or liquid?". In terms of molecular dynamics and thermodynamics it is possible to justify various different views that it is a highly viscous liquid, an amorphous solid, or simply that glass is another state of matter which is neither liquid nor solid.

A solid keeps it's shape unless a force is applied to it -- they do not change shape on their own.

Liquids take the shape of the container they are in.

When you move a liquid into a different container, the liquid changes shape but does not change volume.
