No. This is a myth that was published in a chemistry text and this has been perpetrated. But it is a fallacy. Glass is a brittle amorphous solid.
It is true that drinking from a glass without friction can be challenging because the liquid would not stay inside the glass due to lack of adherence. Friction between the liquid and the glass allows the liquid to be lifted and contained for consumption.
Although the debate over the classification of glass as a solid or supercooled liquid is ongoing, current consensus among scientists is that glass should be considered an amorphous solid rather than a supercooled liquid. The atoms in glass are arranged in a rigid structure, similar to a solid, but lack the long-range order found in true crystals.
The definition of glass is a super cooled liquid. Any liquid that is super cooled takes on the properties of glass. Glass as you think of it is just super cooled silica. What happens is that it is cooled so quickly that it doesn't actually undergo a phase change back to a solid. In reality glass is just an incredibly slow moving liquid.
Glass is not a liquid. It is in fact a solid.
Liquid glass is sodium metasilicate, Na2SiO3. (Wikipedia)
Glass is not a true solid. It has no crystalline structure. It has no set melting point, as it is what is known as a "super cooled liquid". The hotter it gets, the faster it flows. I've read that cathedrals with stained glass that is centuries old, find that the glass is each segment is thicker at the bottom. In other words, the glass has flowed downwards over the centuries.
the volume of any liquid that can fill half of an ordinary glass
The hot liquid could crack a cold glass.
A liquid-in-glass thermometer is a type of thermometer that consists of a glass tube filled with a liquid, typically mercury or alcohol, which expands or contracts with changes in temperature. The level of the liquid in the tube corresponds to the temperature, allowing for temperature measurement.
When a material changes from a solid to a liquid, its particles have higher kinetic energy, leading to a higher thermal energy. In the case of glass transitioning from a solid bowl to a liquid state, the particles in the liquid glass have more freedom to move and vibrate, increasing their thermal energy compared to the solid state.
No, glass is not technically a liquid. It is an amorphous solid, which means it has a disordered atomic structure similar to a liquid but is still considered a solid.
Glass is a solid, not a liquid. Despite its appearance, glass is actually an amorphous solid, meaning its molecules are arranged in a disordered fashion, similar to a liquid, but they are still fixed in place like a solid. This is why glass does not flow or change shape over time like a liquid would.
