amorphous solid water

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 Crystalline s..

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..

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 properties. ..

Wood charcoal is obtained by the destructive distillation of wood. The chief products formed are wood charcoal, wood tar, pyroligneous acid and wood gas (Fig.10.6). However, if wood charcoal is heated strongly, most of the air gets expelled and then if it is placed in water, it will sink ..

Amorphous Carbon - Lamp Black - Lamp Black is also known as Soot. Soot is obtained by the incomplete combustion of carbonaceous, fuels, especially oil fuels, in limited supply of air. The soot settles on the cooler parts of the chamber, and can be collected by scrapping it (Fig.10.5). It ..

Water is the only substance that can exist simultaneously in all the three states of matter, i.e., solid, liquid and gaseous on this earth,. A simple experiment shows the existence of all these three states together. Take a glass half packed with ice cubes and cover it. Th..

Water - About 70-73% of earth is covered by water. Water is available in the form of oceans, seas, rivers, lakes, ponds, pools, polar ice caps and water vapour. The main component of hydrosphere is water. Water exists in all the three form..
