organic amorphous solid

Amorphous Solids - Substances whose particles do not posses a regular orderly arrangement but have short range order. When amorphous solids are heated they become crystalline at some temperature. Properties of amorphous solids are: They do..

Substances whose constituents are not arranged in an orderly manner are called amorphous solids. They are also called pseudo solids and differ from crystalline solids in many respects. The common examples of amorphous solids are glass, ru..

Solids with particles not arranged in a regular fashion. They have only short range order or even the particles are disordered in some case..

Crystalline and Amorphous Solids - Solids have definite shape and volume because the average distance between the molecules or atoms remain constant and do not change with time. The arrangement of molecules inside a solid differ from one to another. This resu..

Solids have definite shape and volume because the average distance between the molecules or atoms remain constant and do not change with time. The arrangement of molecules inside a solid differ from one to anothe..

These are crystalline solids, constituted of very fine crystals, not seen by the naked eye. These solids appear amorphous but are not so because the fine crystals are randomly oriented. Thus even though each individual crystal is anisotropic the polycrystalline materi..

The above properties suggest that the properties of the solids not only depend upon the nature of the constituents, but also on their arrangements. Based on their structural features solids can be classified into three categories: Crystalline solids Amorphous..

When a lead plate and a gold plate are placed one over the other if they are kept under pressure for a period of one or two years. It will be observed that the lead particles have diffused into gold and gold particles have diffused into lead plate. It is believed that fossils of animals like repti..

Heterogeneous catalysis is extensively used in chemical industry. Hence, development, selection and application of solid catalysts forms an important area in surface chemistry studies. The nature of the solid catalyst has profound effects on heterogeneous catalytic reactions. ..

In general, solid waste includes garbage, domestic refuse and discarded solid materials such as those from commercial, industrial and agricultural operations. They contain increasing amounts of paper, cardboards, plastics, glass, old construction material, packaging material an..
