Mercury is the only common metal which is liquid at ordinary temperatures. Mercury is sometimes called quicksilver. … It is a rather poor conductor of heat if compared with other metals but it is a fair conductor of electricity.
Is mercury a electrical insulator?
Mercury is an electric conductor.
Is mercury a good insulator or conductor?
Mercury is a conductor as it can conduct heat well.
Why is mercury not a good conductor of electricity?
Heat energy is conducted by transferring energy of atoms vibrating at high level. … Since high density of mercury, there is no enough room for vibrating mercury atoms. So it can’t be heated easily. So it’s a poor conductor of electricity.
Is mercury corrosive to metal?
It has been shown that metallic mercury reacts with many environments to a sufficient extent to produce compounds that are corrosive to commercial metals. It has been demonstrated that concentrations of mercury compounds as low as 0.5 ppm constitute a serious corrosion hazard for a variety of useful metals and alloys.
Which mercury element is good conductor of electricity?
Copper. One of the most commonly used metals to conduct electricity is copper. As a material, copper is pliable, easy to wrap or solder, which makes it the best choice when large amounts of wiring are needed. Copper’s core electrical function is related to the transmission of electricity and power generation.
Why mercury is the best conductor of heat?
We know that mercury has a large value of the coefficient of thermal expansion. Hence, even the smallest change in temperature is evident in the shape of the mercury container. … All these factors make mercury a good conductor of heat and this is why it has a large application spectrum especially in measuring devices.
Why is mercury considered a metal?
Mercury is a metal because is has free electrons as do all metals. As a result it is a good conductor of electricity as are all metals. that’s why it is called metal. it’s a different thing that it is in liquid state at room temperature.
What happens to mercury when heated?
At room temperature, exposed elemental mercury can evaporate to become an invisible, odorless toxic vapor. If heated, it is a colorless, odorless gas. … When mercury reacts with another substance, it forms a compound, such as inorganic mercury salts or methylmercury.
