amorphous and crystalline solids

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..

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 research has throw..

. 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..

Take hydrated copper (II) sulphate crystals in a test-tube and heat. On heating, the blue crystals in the test tube start turning white. Water vapours are released that condense on the cooler part of the test tube. Collect the water drops in a dish. The crystalline copper sulphate turns ..

In a crystalline solid, the constituent particles (atoms, ions or molecules) are arranged in a regular order. An interaction of a particular crystalline solid with X-rays helps in investigating its actual structur..
