...presentation On NANO Mercury Power Plant (Non Conventional /Renewable) ABSTRACT: power plant is used to production of electricity by so many methods like hydro power plant,nuclear power plant ,gas turbinre plant combined cycle power plant, solar power plant, wind power plant, tidal power plant, diesel generator, petrol generator, this all are power plant run by fuel and generate electricity. i am introducing new type and technology power plant MERCURY: It's the only common metal which is liquid at ordinary temperatures. Mercury is sometimes called quicksilver. It is a heavy, silvery-white liquid metal. It is a rather poor conductor of heat if compared with other metals but it is a fair conductor of electricity. It alloys easily with many metals, such as gold, silver, and tin. These alloys are called amalgams. The most important mercury salts are mercuric chloride HgCl2 (corrosive sublimate - a violent poison), mercuric chloride Hg2Cl2 (calomel, still used in medicine occasionally), mercury fulminate (Hg (ONC) 2, a detonator used...

...manometers, sphygmomanometers, and float valves and other things that have mercury on should be disposed properly. Avoid throwing them in rivers for mercury is toxic and poisonous. Mercury * Mercury is a chemical element with symbol Hg and atomic number 80. It is commonly known as quicksilver and was formerly named hydrargyrum. * Mercury poisoning can result from exposure to water-soluble forms of mercury (such as mercuric chloride or methylmercury), inhalation of mercury vapor, or eating seafood contaminated with mercury. * Mercury is used in thermometers, barometers, manometers, sphygmomanometers, float valves, mercury switches, mercury relays fluorescent lamps and other devices, through concerns about the element's toxicity have led to mercury thermometers and sphygmomanometers being largely phased out in clinical environments in favour of alternatives such as alcohol- or galinstan-filled glass thermometers and thermistor- or infrared-based electronic instruments. Mercury can be found in four different forms: * Mercury metal, which is a silver-gray liquid, is harmful to humans when it is exposed into the air and consequently breathed into the lungs. * Methylmercury "may be taken into the body by eating certain saltwater and freshwater fish, especially larger fish at the top of the food chain, such as shark, swordfish, largemouth bass, and chain pickerel." * Inorganic mercury compounds can be found in batteries, over the counter drugs, ointments, nasal...

...Introduction to Chemistry I (MAE1106) Chapter 1: Properties, Measurement and Units Matter: All things we can see, or touch, whether books, pencils, telephones, or people as they have some thing in common. They are all composed of matter which is defined as anything that takes up space and has mass. Matter is generally considered to be a substance (often a particle) that has rest mass and (usually) also volume. Mass and weight are not really the same. The mass of a body is a measure of its resistance to a change in its velocity. Weight refers to the force with which an object of a certain mass is attracted by gravity to the earth or other body that may be near such as moon. The volume is determined by the three-dimensional space it occupies, while the mass is defined by the usual ways that mass is measured. Matter is also a general term for the substance of which all observable physical objects consist Properties of Substances Physical (Properties and Changes) A physical property is one that is displayed without any change in composition. (Intensive or Extensive) 1. Intensive: A physical property that will be the same regardless of the amount of matter. density: m/v • color: The pigment or shade • conductivity: electricity to flow through the substance • malleability: if a substance can be flattened • luster: how shiny the substance looks 2. Extensive: A physical property that will change if the amount of matter changes. • mass: how much...
