When an amorphous material is heated, it gradually softens and starts to flow like a liquid without a well-defined melting point. This behavior is known as glass transition, and it occurs because amorphous materials lack a regular crystalline structure that would normally lead to a distinct melting point.
What else can I help you with?
Contrast the changes in a crystalline solid as it is heated to those in an amorphous solid that is heated?
As a crystalline solid is heated, it undergoes a well-defined melting point where its ordered structure breaks down to a disordered liquid state. In contrast, an amorphous solid softens gradually upon heating without a distinct melting point, as its structure lacks long-range order. The amorphous solid may eventually become a viscous liquid upon further heating.
What is the difference between an amorphous and crystalline solid when heated?
When heated, amorphous solids do not have a sharp melting point and soften gradually over a range of temperatures, while crystalline solids have a specific melting point at which they transition from a solid to a liquid state. Amorphous solids lack a regular and repeating atomic structure, leading to their softening behavior, whereas crystalline solids have a well-defined and orderly atomic arrangement that allows for a distinct melting point.

Is melting wax a solid liquid or gas?
that's a good question. It is a amorphous solid because it expands or gradually loses shape.

What does amorphous sediment mean?
Amorphous Crystals ¤Amorphous urates are found in acid urine. These crystals may appear pink on gross analysis and yellow microscopically (Figure 2-12). These crystals appear as granules in the urine sediment. Amorphous phosphates are found in alkaline urine. These granules are colorless microscopically and also appear granular when viewed microscopically. Occasionally amorphous material may appear in clumps or masses. It may be difficult to distinguish amorphous crystals from bacteria since they may be of the same size when viewed microscopically. However, amorphous crystals are soluble in opposing acid or alkaline solution; bacteria will not. Amorphous urates will also dissolve when heated. cited from: http://www.tetonnm.com/pics/MESSamplePages/1-893441-10-5.pdf retrieved 4/11/2009
Is ceramic tile crystalline or amorphous?
amorphous
Particles are arranged in no particular order in this type of solid?
amorphous
How do crystalline and amorphous solids differ?
Crystalline solids have a well-defined geometric structure with particles arranged in a repeating pattern, giving them a sharp melting point and distinct faces. On the other hand, amorphous solids lack long-range order in particle arrangement, leading to a more random structure. This results in amorphous solids having a gradual softening when heated compared to the sharp melting point of crystalline solids.
What is amorphous sulphur?
Amorphous sulfur is a non-crystalline form of sulfur that does not have a well-defined structure like regular crystalline sulfur. It is often produced by rapidly cooling molten sulfur, resulting in a more random arrangement of sulfur atoms. Amorphous sulfur can exhibit different physical and chemical properties compared to its crystalline form.
