Question

(e) Metals are bad conductors of heat. it true or false​

Answer 1

Metals and stone are considered good conductors since they can speedily transfer heat, whereas materials like wood, paper, air, and cloth are poor conductors of heat. These conductive properties are rated based on a “coefficient” which is measured relative to silver.

Answer 2

$\LARGE{ \underline{\boxed{ \bf{\blue{Required \: answer:}}}}}$

Metals are bad conductors of heat.

• False (In most of the cases).

Metals are generally good conductors of heat and electricity due to the free & delocalized electrons inside their lattice structure.

Explanation:-

Now how the heat is transferred? We know that heat is transferred through a solid by the process of conduction. It is because the atoms are closely packed to each other, hence vibrations can easily travel through.

The free or delocalized electrons in the lattice structure carries the kinetic energy (because heat is average kinetic energy) throughout the solid. The electrons move through the solid and hits the atoms which causes the vibrations.

In this way, Heat is easily transferred through the metals because of abundance free electrons. Hence, Metals are good conductors of heat.
