Why metals are both good heat and electrical conductors?

Answer: Metals are an excellent conductor of electricity and heat because the atoms in the metals form a matrix through which outer electrons can move freely. Instead of orbiting their respective atoms, they form a sea of electrons that surround the positive nuclei of the interacting metal ions.

Why are good conductors of heat also good conductors of electricity?

Because both phenomena are about kinetic energy. Heat is random jiggling kinetic energy of electrons, electricity is directional kinetic energy of them. If electrons can easily pass their motion to other electrons in the material, then the material is a good conductor of both heat and electricity.

Why are metals good conductors of heat and electricity whereas non-metals are not?

WHY METALS ARE GOOD CONDUCTORS OF ELECTRICITY. The metal has free electrons which helps them in the conduction of electricity, while non-metals have no free electrons, making them poor conductors of electricity.

Why is a good conductor of electricity also a good conductor of heat quizlet?

Why is a good conductor of electricity also a good conductor of heat? Both types of conduction are via free-moving electrons. Five thousand billion billion freely moving electrons in a penny repel one another. The electrons are attracted to the same number of protons in the penny.

Are all good conductors of heat also good conductors of electricity?

As a general rule, substances which are good conductors of heat are also good conductors of electricity. Thus, all metals are conductors, whereas air, (pure) water, plastics, glasses, and ceramics are insulators.

Why are metals good conductor of electricity whereas glass is a conductor of electricity?

Metals are good conductor of electricity as they have low resistivity and they have free electrons. Glass is a bad conductor of electricity as it has high resistivity and have no free electrons.

Are generally good conductors of heat and electricity?

Metals are elements that are good conductors of electric current and heat. They also tend to be shiny and bendable – like copper wire. Most metals are good thermal AND electrical conductors. Metals also generally have low specific heat (which means they heat up quickly).
