Is The Glass Solid Or Liquid?
Is the glass solid or liquid? Of course it is solid, but in fact, the glass is not solid, it is a very slow flow of semi-solid semifluid state. Many of the old churches in the West have been used for centuries, and the windows are thick and thin, that is, when a flat glass is vertically erected for 100 years, it becomes thinner and thicker below, showing a liquid nature, similar to the fact that the soap film is thin and thick due to gravity.Vetrosa
Glass is neither crystalline nor amorphous, nor is it a polymorphic or mixed state. The theoretical name is called the glass state. The characteristics of glassy state at room temperature are: Short-range order, that is, in the range of several or dozens of atoms, the atoms are arranged in an orderly manner, showing the crystal characteristics. Long-range disorder, that is, after increasing the number of atoms, becomes a disorderly arrangement of state, the degree of chaos similar to liquid. On the macro level, glass is a solid substance. Glass is such a substance. The cause of the glass structure is that the viscosity of the glass is too fast with the temperature, and the crystallization speed is too slow. When the temperature drops and the crystallization is just beginning, the viscosity becomes very large, and the movement of atoms is limited, resulting in this result. Therefore, the glassy state is similar to the solid liquid, the atoms in the matter are always in the process of crystallization.Vetrosa
As a result, the atoms in the glass appear to be stationary, but there is still a force between the atoms to make it a reordering trend. is not a stable state, which is different from the state of the atom in paraffin wax. Therefore, the same is not crystal, at room temperature, paraffin is completely solid, and glass can be seen as a very viscous liquid. This study is a major breakthrough in understanding metastable materials, which will make it possible to further develop new materials such as metallic glass. In addition, it is possible to reduce metal defects substantially if the internal structure of the glass is formed by manipulating the metal during cooling.Vetrosa
Some materials are crystallized when cooled, and their atoms are arranged in a highly regular pattern called "lattice". But when the glass is cooled, the atoms are stuck together, almost randomly arranged, hampering the formation of the regular lattice.Vetrosa
