Which Is The Best Conductor Of Heat And Electricity?

Which is a good conductor of heat and electricity?

Metals like copper and aluminium have the highest thermal conductivity while steel and bronze have the lowest.

As copper is an excellent conductor of heat, it is good for heat exchanger also.

Gold, Silver, Iron etc are also some examples of good heat conductors as well as electrical conductors..

Why is diamond a bad conductor of heat and electricity?

Solution : In diamond, each C-atom is sp3 hybridised and is tetrahedrally bonded to four carbon atoms. Diamond does not have free electrons. Since the conduction of electricity requires the presence of free electrons, diamond is a bad conductor of electricity.

Which metal is the poor conductor of electricity?

Solution : Bismuth and tungsten are poor conductors of electricity.

What are insulators give 5 examples?

Examples of insulators include plastics, Styrofoam, paper, rubber, glass and dry air.

What are 5 good conductors?

Is Diamond a good conductor of heat and electricity?

Unlike most electrical insulators, diamond is a good conductor of heat because of the strong covalent bonding and low phonon scattering. Thermal conductivity of natural diamond was measured to be about 2200W/(m·K), which is five times more than silver, the most thermally conductive metal.

Is oil a good conductor of electricity?

Oil is an Insulator i.e a Bad Conductor of Electricity. … As an Insulator, the oil prevents the outer metallic casing from being electrocuted and being a Good Conductor of heat, it carries the heat from the core to the casing for dissipation.

Is Diamond a bad conductor of electricity?

In a graphite molecule, one valence electron of each carbon atom remains free, Thus making graphite a good conductor of electricity. Whereas in diamond, they have no free mobile electron. Hence there won’t be flow of electrons That is the reason behind diamond are bad conductor electricity.

Which is the bad conductor of electricity?

Materials like glass and plastic are poor electrical conductors, and are called insulators. They are used to stop electricity from flowing where it is not needed or where it can be dangerous, such as through our bodies.

Is Gold the best conductor of electricity?

Gold is used as a contact metal in the electronics industry as it is a good conductor of both electricity and heat. … Gold wire Gold is ductile: it can be drawn out into the thinnest wire.

What is the best insulator?

Plastic, rubber, wood, and ceramics are good insulators. These are often used to make kitchen utensils, such as saucepan handles, to stop heat from flowing up to burn the cook’s hand. Plastic coating is also used to cover most electrical wires in appliances. Air is also a good insulator of heat.
