Is mercury used as an insulator?

The insulators are those substances, through which heat energy cannot flow. Any material that does not allow heat or any electricity to go through it is known as an insulator. Here in the question copper and mercury both are good conductors. They allow heat and current to go through them and they are also metals.

Is mercury used as a conductor?

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.

Is mercury the best conductor of electricity?

Due to the nature of materials it affects the flow of current. Both iron and mercury are metals and considered as conductors of electricity. But iron is a better conductor than mercury. Note: The current flowing through the conductor is inversely proportional to the resistance offered.

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 element a good conductor of heat?

Copper has a very high thermal conductivity and is much cheaper and more available than silver, which is the best metal of all for conducting heat.

Why is mercury used in electrical switches?

A mercury switch is an electrical switch that opens and closes a circuit when a small amount of the liquid metal mercury connects metal electrodes to close the circuit. This design is used in relays in industrial applications that need to switch high current loads frequently.

Is mercury better conductor than copper?

whereas in liquids mercury is the better conductor. If you buy a kilogram of Aluminium and a kilogram of copper and make yourself wires of the length required by you, you will find that Auminium wire is twice as conductive as copper and also aluminium costs half of that of copper.

Is mercury highly reactive?

Properties of Mercury Mercury is less reactive than its neighboring metals, including cadmium and zinc. One reason that mercury is more inert than other elements is because it doesn’t give up its valence electrons easily.

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.

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.

Is it OK to touch mercury?

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.
