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

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.

Why is metal a better conductor of heat than glass?

Copper is a better heat conductor than glass. In general, we think of metals as good conductors. In fact, metals vary widely in their conductivity but, overall, they are better conductors of heat than most liquids and gasses. A longer wire will conduct less heat from one end to the other.

Why is glass a bad conductor of heat?

Glass is a very poor heat conductor. It has one of the lowest possible heat conduction a solid (without air trapped in it) can possibly have, this is mostly due to its lack of ordered crystal structure. Since it’s an insulator, the electronic contribution to the thermal conductivity is very small.

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

Metals are good conductors of heat and electricity because they have free electrons whereas non-metals are not good conductors of heat and electricity because electrons are not free to move in non-metals.

Are metals good or bad conductor of heat?

Metals are good conductor of electricity but poor conductor of heat.

Why are metals good electrical conductors?

The electrons present in the outermost shell of the metal are very loosely bound because the nucleus has very little attraction on the outermost shell electrons. So, the metals conduct electricity due to the presence of free electrons. So, metals are good conductors of electricity because metals have free electrons.

Is glass a bad conductor?

The electrons in the metal are loosely bound while the electrons in the glass are tightly bound together. Glass has one of the lowest possible heat conduction a solid. Glass is a bad conductor of electricity as it has high resistivity and has no free electrons.

Are most metals good or bad conductors of heat explain?

Most metals are good conductors of heat. This is because the molecules in metals vibrate and hit the nearby molecules to transfer the heat energy, rather than moving from one place to the other.

Is metal a good conductor of heat?

Metals are elements that are good conductors of electric current and heat. They also tend to be shiny and bendable – like copper wire. The majority of elements in the periodic table are metals.

Why are metals good conductors?

Metals are good conductors (both of heat and electricity) because at least one electron per atom is free: i.e., it is not tied to any particular atom, but is, instead, able to move freely throughout the metal.
