What are 4 properties of mercury?

Mercury has a melting point of -38.9oC, a boiling point of 356.7oC, and is the only metal to remain in liquid form at room temperature. Droplets of liquid mercury are shiny and silver-white with a high surface tension, appearing rounded when on flat surfaces.

What are 3 physical properties of mercury?

Mercury is a silvery-white, shiny metal, which is liquid at room temperature….Physical Properties.

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.

What is mercury used in today?

Mercury is used in fluorescent lamps, thermometers, float valves, dental amalgams, in medicine, for the production of other chemicals, and to make liquid mirrors.

What is the symbol of mercury?

Hg
Mercury/Symbol

What is mercury used for today?

How is mercury used in everyday life?

Mercury can be used to make thermometers, barometers and other scientific instruments. Mercury conducts electricity and is used to make silent, position dependent switches. Mercury vapor is used in streetlights, fluorescent lamps and advertising signs. Mercuric oxide (HgO) is used to make mercury batteries.

What are 5 facts about mercury?

It’s not known who discovered Mercury.

• A year on Mercury is just 88 days long.
• Mercury is the smallest planet in the Solar System.
• Mercury is the second densest planet.
• Mercury has wrinkles.
• Mercury has a molten core.
• Mercury is only the second hottest planet.
• Mercury is the most cratered planet in the Solar System.

How do you identify mercury?

The most commonly accepted methods of assessing mercury exposure are to test urine or blood. Both tests usually measure levels of total mercury (elemental, inorganic and organic). Elevated mercury in urine usually indicates exposure to an elemental or inorganic source of mercury, such as from a job that uses mercury.

Can you touch mercury?

If you touch it, a small amount may pass through your skin, but not usually enough to harm you. Mercury is most harmful when you breathe in the vapors that are released when a container is open or a spill occurs. Pregnant women, infants and young children are particularly sensitive to the harmful effects of mercury.

Which is one of the properties of a wave?

​Properties of Waves The basic properties (parts) of a wave include: frequency, amplitude, wavelength and speed. Frequency Frequency is a measure of how many waves pass a point in a certain amount of time. The higher the frequency, the closer the waves are together and the greater the energy carried by the waves will be.

What are the properties and properties of mercury?

1 Atomic symbol: Hg 2 Atomic number: 80 3 Element Category: Transition metal 4 Density: 15.534g/cm³ 5 Melting Point: -38.9°C (102°F) 6 Boiling Point: 356.9°C (674.4°F) 7 Electrical Resistivity: 95.8 microhm/cm (20°C)

What kind of electrical conductivity does Mercury have?

Electrical Resistivity: 95.8 microhm/cm (20°C) Characteristics At room temperature, mercury is a thick, silvery liquid with a very high density and low heat conductivity. It has a relatively high electrical conductivity and readily forms amalgams (alloys) with gold and silver.

What are the properties of a transverse wave?

In a transverse wave the higher the wave, the higher the amplitude. Sounds with greater amplitude will be louder; light with greater amplitude will be brighter. Wavelength is a measure of the distance from the crest on one wave to the crest on the very next wave. Shorter wavelengths are influenced by the frequency.
