amorphous solid

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 called "Sl..

Properties of Matter - A solid has certain characteristics: According to modern theory, the molecules of a solid are fixed in relation to each other. They vibrate in place, but do not wander around. This accounts for the fact that a solid keeps its own shape. Soli..

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..

Any amorphous and transparent solid that is a product of the solidification of a liquid is called glass. However, glass is generally referred to as the transparent substance obtained when white sand is fused with oxides and carbonates of alkaline earth metals and the molten mixt..

Summary - All material is made from small moving particles called atoms. Materials can be solid, liquid or gaseous, depending upon the arrangement and freedom of movement of these particles. Diffusion is the movement of particles from a place of high concentration to a place of lower conc..

Boron is an extremely hard solid with a high melting point (2450 K), and boiling point (3970 K). It has low electrical and thermal conductivities. Two allotropic forms of boron are, amorphous boron (dark brown), and crystalline boron (black metallic luster). Boron occ..

. This type-of glass (trade-name-Pyrex/corning/Borosil) can withstand sudden changes in temperature and is used for making laboratory glassware. Another route to glass formation is provided by the sol-gel process. Glass is not a true solid and has no definite melting point. It softens whe..

Ceramics - Besides being useful, chemicals find use in artifacts as well. Ceramics, paints, varnishes, glass, cement are various other useful substances that contain various chemicals as their components. Construction industry is the major beneficiary of such substances. Of late, continuing researc..
