what are two properties of amorphous solids

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..

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 not have sharp melting point..

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 results in two types of solids Crystall..

Coal, Coke, Charcoal (or wood charcoal), Animal Charcoal (or bone black), Lamp black, Carbon black, Gas carbon and Petroleum coke. Diamonds and graphite are two crystalline allotropes of carbon. Diamond and graphite both are covalent crystals. But, they differ considerably in their ..

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

1. Calcium oxide is a white amorphous solid. 2. It is not decomposed further when heated, but produces a white brilliant light above 2732 o F. This light is called lime light. 3. It combines vigorously with water to form slaked lime (Calcium hydroxide). The process is ..

The magnetic properties of materials are a consequences of magnetic moments associated will individual electrons. The magnetic moment of an electron is due to its orbital motion and also due to its spin around its own axis. A moving electron may be considered to be a small current loop, g..

Dielectric Properties of Solids - Insulators do not conduct electricity because the electrons present in them are held tightly to the individual atoms or ions and are not free to move. However when electric field is applied polarization takes place because the nucleus is attract..

Calcium oxide (quicklime) is a white amorphous solid. On heating, quicklime (CaO) glows at high temperatures. This glow of white dazzling light is called lime light. Quicklime melts at 2870 K (2597C). On exposure to the atmosphere, it absorbs moisture and carbon dioxide to fi..
