What mercury is used to measure?
Mercury is used to measure atmospheric pressure in barometers and to regulate temperature in thermometers. It is also used in some industrial processes and scientific instruments for its unique properties like high density and low surface tension. However, the use of mercury is decreasing due to its toxicity and environmental impact.
What does the sign of mercury mean?
Mercury got its name from the Roman god of commerce and trade. Mercury was the Roman counterpart to the Greek god Hermes. He was considered to be the messenger of the gods. He is portrayed with a winged hat and winged sandals. He carries a staff wound about with snakes called a caduceus which is used as an emblem in medicine and pharmacy, showing the god's connection with these fields. The planet closest to the sun is named after Mercury. It received its name because it quickly appears and disappears from our view like the fast-running messenger. The element called quicksilver with the symbol Hg is also called Mercury. It is liquid at room temperature, and so is quick like the quick-footed god. In romance languages, the day of the week called Wednesday in English is named for Mercury (cf. French mercredi and Spanish miercoles)
Which shuttle found Mercury?
The MESSENGER spacecraft was used to find and study the planet Mercury. It orbited Mercury from March 2011 to April 2015 and provided valuable data about the planet's surface, composition, and magnetic field.
What is the purest form of mercury?
The purest form of mercury is elemental mercury, which exists as a liquid at room temperature. It is a heavy, silvery metal that is commonly used in thermometers and other scientific instruments. Mercury is a transition metal with the chemical symbol Hg (from the Latin hydrargyrum) and atomic number 80.
Origin of the name Mercury?
Depending on what you mean, "Mercury" applies to a lot of things in our world, but mostly, the name originates from the Roman messenger god known as Mercury.The Roman Messenger God.

Mercury has influenced the name in a lot of things in a variety of scientific fields such as the planet, Mercury, and the element Mercury. The world mercurial is also derived from his name - it commonly is used to describe a something or someone as erratic, volatile, or unstable, derived from his swift flights from place to place.The Planet. Mercury is the smallest and innermost planet in the solar system, orbiting the sun once every 88 days. Mercury is bright when viewed from Earth from a telescope, but not easily seen as it is very close to the sun. The only times that the planet is visible is in the early morning or evening twilight. Little is known about this planet but there have been spacecraft that were launched from Earth to investigate the planet - the Mariner 10 and the MESSENGER. Mercury has a very similar appearance to the moon, with heavy craters. It has no satellites (or moons) of its own and has no substantial atmosphere, but unlike the moon, it has a large iron core, which generates a magnetic field about !% stronger than that of Earth. Recorded observations of Mercury have dated back to the first millennium BC. Originally, Greek astronomers believed Mercury to be two separate planets - one visible only at sunrise, called Apollo, and the other only visible at sunset, called Hermes. The English name for the planet is Mercury, which originates from the Roman god, Mercury.The Element. The element, mercury, is also known as quicksilver, or hydragyrum. It is a chemical element represented in the Periodic Table with the symbols: Hg. Its atomic number is 80. Mercury is a heavy, silvery d-block metal and is one of the five metals that are liquid at or near room temperature and pressure. Mercury is used in barometers, thermometers, manometers, sphygomomanometers, float valves, and other scientfic tools. Exposure to Mercury can lead to poisoning.Mercury was known to the Chinese and found in Egyption tombs that date from 1500 BC. In China and Tibet, mercury was thought to prolong life, heal fractures, and maintain generally good health. China's first emperor, Qin Shi, was said have been buried in a tomb that contained rivers of mercury to represent the rivers of China.

By 500 BC, mercury was used to make amalgrams with other metals. The Indian word for alchemy was Rasavatam, which means "the way of mercury".
