classification of matter according to source

Sewage that includes organic matter, animal and human excreta-one of the major pollutants of water in the urban and rural areas is the sewage. The sewage most often contains the organic matter that encourages the growth of microorganisms. These organisms besides spreading disea..

Sources of Ammonia - Ammonia is generally obtained from a) Ammoniacal liquor obtained by the destructive distillation of coal. b) The destructive distillation of nitrogenous organic matters such as horns, hoofs, bones etc. of animals. c) Ammonium salt..

Expansion of Matter - Matter expands on heating, i.e., solids, liquids and gases expand on heating. Let us consider expansion of solids: Three types of expansions are considered in case of solids. This classification is done according to the shape of the soli..

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 concentration ..

A positron has the same mass as an electron but an opposite charge of +e. When an electron and a positron come close to each other, they annihilate or destroy each other. Their masses are converted into energy according to Einstein's relation, and the energy thus obtained is released in ..

Under certain experimental conditions, a beam of particles (for example, electrons ) can exhibit wavelike properties. Such matter waves are governed by the laws of quantum physics. The wavelength is inversely proportional to the momentum of the particles. These are also known as de Brogl..

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. Solids are usually crystalline. A solid is a crystal..

Wave Nature of Particles - The suggestion that matter may have wave like properties was first put forwarded in 1924-1925 by Louis De Broglie. He argued that if light, which consists of waves according to classical picture, can sometimes behave like particles, then it should be p..

Rich sources of Niacin are liver, yeast, whole grains, cereals and pulses. Milk, fish, eggs and vegetables are the moderate sources of niaci..

Rich sources of vitamin B 6 are egg, fish, milk and meat. Wheat, corn, cabbage, roots and tubers are some other sources of vitamin B ..
