thermal conductivity is a property describing the material’s ability to conduct heat and is not dependent on the amount of material present.

Explanation:

Thermal conductivity is a physical property of materials that enable heat transmission. This means that when a body has thermal conductivity, heat passes from the body of higher temperature to another of lower temperature that is in direct contact with it.

In other words:

This property implies the ability of a material or substance to transfer the kinetic energy of its molecules to adjacent ones or to other materials (or substances) with which it is in contact.
