Question

How would you convert a crystalline solid into an amorphous solid?

Answer 1

1. A crystalline solid can be converted into an amorphous solid by rapid cooling or quenching of its molten form.
2. When a crystalline solid is melted and then cooled rapidly, the atoms or molecules do not get sufficient time to arrange themselves into a regular, repeating pattern.
3. As a result, the substance solidifies in a disordered or irregular structure, which is characteristic of amorphous solids.
4. For example, when molten silica (SiO₂) is cooled rapidly, it forms glass, which is an amorphous solid.
5. Similarly, metallic glasses are formed by rapidly cooling molten alloys.
