Amorphous solids are distinguished by which of the following?

Amorphous solids are characterized by their lack of a long-range order in their atomic arrangement, meaning that the particles within these solids are arranged randomly. This randomness distinguishes them from crystalline solids, which have a consistent, repeating pattern. As a result, amorphous solids do not exhibit sharp melting points; rather, they soften over a range of temperatures instead of transitioning from solid to liquid at a specific point. This distinction is central to understanding the physical properties of materials and their behaviors in various applications.
