Is glass a liquid or a solid?
Liquid.
Being neither liquid, nor solid, explaining glass is a lot harder than some might think. In a glass, molecules still flow, but at a very low rate that it’s barely perceptible. As such, it’s not enough to class glasses as a liquid, but neither as a solid. Instead, chemists classify glasses as amorphous solids— a state somewhere between those two states of matter. There’s also a thing called metal glass – a class of materials that are three times stronger than titanium and have the elastic modulus of bone, all while being extremely lightweight
