CHEMISTRY GLOSSARY
xenon → ksenon
Xenon was discovered by Sir William Ramsay, Morris W. Travers (England) in 1898. The origin of the name comes from the Greek word xenos meaning stranger. It is heavy, colourless, odourless, noble gas. Reacts only with fluorine. Xenon is obtain from the small quantities in liquid air. Used for filling flash lamps and other powerful lamps. Electrical excitation of xenon produces a burst of brilliant white light. Also used in bubble chambers and modern nuclear power reactors.
zirconium → cirkonij
Zirconium was discovered by Martin Heinrich Klaproth (Germany) in 1789. The origin of the name comes from the Arabic word zargun meaning gold colour. It is grey-white, lustrous, corrosion-resistant metal. Exposed surfaces form oxide protective film. Zirconium is found in many minerals such as zircon and baddeleyite. Used in alloys such as zircaloy this is used in nuclear applications since it does not readily absorb neutrons. Also baddeleyite is used in lab crucibles. Used in high-performance pumps and valves. Clear zircon (ZrSiO4) is a popular gemstone.
water jet vacuum pump → vodena sisaljka
The water jet vacuum pump or vacuum aspirator is one of the most popular devices that produces vacuum in laboratories. The rapid flow of water through the device creates a vacuum in a side-arm that is connected to a vacuum application such a Buchner flask. The water jet vacuum pump creates a vacuum by means of Venturi effect named after the Italian physicist Giovanni Battista Venturi (1746–1822). The Venturi effect is the reduction in fluid pressure that results when a fluid flows through a constricted section of pipe. Water jet pumps are manufactured of glass, plastic or metal, depending on the conditions in which they are used.
