1 Can youtell more about Mercury/Quick sliver/Padarasam? Mercury ( புதன் கிரகம் )being the name of the 1st planet in solar system and is the quickest planet of all to completeone revolution around the SUN. Named for thefleet-footed Roman messenger god, Mercury is the closest planet to the sun,zipping around our parent star at an average of 36 million miles away. However,Mercury’s orbit is nota perfect circle. The planet can pass as close as 29 million miles and as faraway as 43 million miles. Mercury spins slowly compared to Earth, soone day lasts a long time. Mercury takes 59 Earth days to make one fullrotation. But a year on Mercury goes fast. Because it's the closest planet tothe sun, it goes around the Sun with anorbital speed of about 47.87 km/s , which is a period of about 87.97 Earthdays. Between this rapidorbital period and its slow rotational period, a single year on Mercury isactually shorter than a single day. Mercury is also the smallest planet in the solar system, measuring just3,032 miles wide at its equator. That makes it only slightly larger thanEarth’s moon.Hydragirum (mercury) being the only flowing metal that has the quickest molecular motion amongall the metals.Hence the quick word is for the quicker molecular motion andsilver is its color. Mercury is also known as “quicksilver,” a reference toits mobility. Speed and mobility were characteristics ofthe Roman god, Mercury, who served as a messenger to all the other gods andshared his name with the planet nearest the sun. Mercury is a chemical element with the symbol Hg andatomic number 80. It is commonly known as quicksilver andwas formerly named"Hydrargyrum". A heavy, silvery d-block element,mercury is the only metallic element that is liquid at standard conditions fortemperature and pressure; the only other element that is liquid under theseconditions is the halogen bromine, though metals such as cesium, gallium, andrubidium melt just above room temperature. Mercury occurs in deposits throughout the world mostly ascinnabar (mercuric sulfide). The red pigment vermilion isobtained by grinding natural cinnabar or synthetic mercuric sulfide.Mercury isextracted by heating cinnabar in a current of air and condensing the vapor. Mercury was found inEgyptian tombs that date from 1500 BC. In China and Tibet,mercury use was thought to prolong life, heal fractures, and maintain generallygood health, although vapor leads to serious adverse healtheffects. The ancient Greeksused cinnabar (mercury sulfide) in ointments; the ancient Egyptians and theRomans used it in cosmetics. The element mercury is named for the Roman godMercury. Mercury is the only element to retain its alchemical name as itsmodern common name. Mercury dissolves many metals such as gold and silver to form amalgams.Iron is an exception. Mercury readilycombines with Aluminium to form a mercury-aluminium amalgam when the two pure metals come intocontact. Since the amalgam destroys the aluminium oxide layer which protectsmetallic aluminium from oxidizing in-depth (as in iron rusting), even small amounts of mercurycan seriously corrode aluminum. For this reason, mercury is notallowed aboard an aircraft under most circumstances because of the risk of itforming an amalgam with exposed aluminium parts in the aircraft. Mercury is used inthermometers, barometers, manometers, sphygmomanometers, float valves, mercuryswitches, mercury relays, fluorescent lamps and other devices. Amidst concerns about the element's toxicityhave led to mercury thermometers and sphygmomanometers being largely phased outin clinical environments in favor of alternatives such as alcohol- orgalinstan-filled glass thermometers and thermistor- or infrared-based electronicinstruments. Likewise, mechanical pressure gauges and electronic strain gaugesensors have replaced mercury sphygmomanometers. Mercury does notreact with most acids. Mercuryis a relatively poor conductor of heat, while Most metals are excellent thermal conductors. Mercury remains inuse in scientific research applications and in amalgam for dental restoration.. It is also used in fluorescent lighting. Electricity passed through mercuryvapor in a fluorescent lamp produces short-wave ultraviolet light, which thencauses the phosphor in the tube to fluoresce, making visible light. USES: 1.Mercury is used inspirit lamps. 2.Used indentistry to fill cavities caused by tooth decay. 3.Mercuric iodide isused in dermatology. 4.Mercury oxide isused as a medicine for eye inflammation. 5.Mercury(II)fulminate is a primary explosive which is mainly used as a primer of acartridge in firearms. 6.The disinfectantmercury compound thimerosal is an organomercury compound found in vaccines,tattoo inks, contact lens solutions, and cosmetics. 7.Some transittelescopes use a basin of mercury to form a flat and absolutely horizontalmirror, useful in determining an absolute vertical or perpendicular reference.Concave horizontal parabolic mirrors may be formed by rotating liquid mercuryon a disk, the parabolic form of the liquid thus formed reflecting and focusingincident light. Today, the useof mercury in medicine has greatly declined in all respects, especially indeveloped countries.Thermometers and sphygmomanometers containing mercury were invented in theearly 18th and late 19th centuries, respectively. In the early 21st century,their use is declining and has been banned in some countries, states andmedical institutions. In 2002, the U.S. Senate passed legislation to phase outthe sale of non-prescription mercury thermometers. In 2003, Washington andMaine became the first states to ban mercury blood pressure devices.

A2 An attempt was made to make a holemany years ago in the USSR (now Russia) but it was only possible to reach 12.3 km deep andthat distance only represents 0.2% of the total distance to the nucleus. They could onlyreach that distance because the temperature is very high.They did not have machines that resist high temperatures, and there is nomachine that can be so long to reach the core of the earth.
