What are the properties and uses of mercury?
Although many liquids could be used in pressure measuring devices, mercury is used because its high density requires less space. It is also a good conductor of electricity, so it is a useful component of electrical switches. Mercury is also used in dental fillings, paints, soaps, batteries, and fluorescent lighting.
Why is mercury element important?
As a good conductor of electricity, mercury is often used in many products such as switches and batteries. It is used to amalgamate gold and silver in small scale mining activities because it readily combines with other metals.
What are 5 uses of mercury?
Uses of Mercury Mercury metal has many applications. Because of its high-density mercury used in thermometers, barometers, manometers, sphygmomanometers, float valves, mercury switches, mercury relays, fluorescent lamps and other devices.
What is special about mercury?
Mercury is the only planet which doesn’t rotate exactly once every year – instead rotating three times for every two orbits of the Sun. This is because it is nearly tidally locked to the Sun. The orbit of Mercury was important in proving Albert Einstein’s theory of General Relativity.
What are the functions of mercury?
Mercury is used primarily for the manufacture of industrial chemicals or for electrical and electronic applications. It is used in some liquid-in-glass thermometers, especially those used to measure high temperatures.
Is mercury poisonous to touch?
Mercury is a very toxic or poisonous substance that people can be exposed to in several ways. If it is swallowed, like from a broken thermometer, it mostly passes through your body and very little is absorbed. If you touch it, a small amount may pass through your skin, but not usually enough to harm you.
