Make a Fire Extinguisher In order to put out a fire‚ one of three things must be removed from it: heat‚ fuel‚ or oxygen. Knowing this‚ firefighters don’t always use water to put out a fire. Materials * Empty soda bottle * 5 tablespoons of vinegar * 1/2 tablespoon of baking soda * Tea light candle Procedure: Ask an adult for permission before lighting the candle! 1. Light the candle. 2. Pour the vinegar into the bottle and add the baking soda. (You may want to use a funnel

multistage ejector systems will simplify your task of designing vacuum-producing equipment for any pressure. F. DUNCAN BERKELEY GRAHAM MANUFACTURING CO.‚ INC.‚ BATAVIA‚ N.Y. B ecause of overlapping performance‚ it’s often a lengthy problem to arrive at the most economical design of an ejector. In practically every new application of high vacuum‚ we find it necessary to investigate thoroughly the many available means of producing vacuum to reduce equipment and operating costs to a practical and

Chirality – Isolation of Limonene from Citrus Fruits Introduction: Terpenes are a large and varied class of hydrocarbons produced by a wide variety of plants. Many essential oils belong to the terpene class. They are made up of two or more five carbon units that are called isoprenes. Limonene is a terpene that can be separated from orange peels almost 100% in the (R)-(+)-limonene form. Other citrus fruits like lemons‚ grapefruits‚ limes‚ and tangerines contain the compound as well. The

Two years later‚ pursuing a suggestion by Galileo‚ he filled a glass tube 4 ft (1.2 m) long with mercury and inverted the tube into a dish. He observed that some of the mercury did not flow out and that the space above the mercury in the tube was a vacuum. After much observation‚ he concluded that the variation of the height of the mercury from day to day was caused by changes in atmospheric pressure. He never published his findings. His work in geometry aided in the eventual development of integral

between atmospheric pressure and the pressure of whatever they are attached to. Vacuum gauges are differential gauges that measure how far BELOW atmospheric pressure the pressure is in a vessel or pipe. Gauges that measure "gauge pressure" are just differential gauges that are calibrated to measure zero at atmospheric pressure. Absolute pressure gauges would only read "zero" if they were attached to an absolute vacuum. A common type of absolute pressure gauge is a barometer. Strictly speaking‚ a mercury
