Does the conductivity increase or decrease?
It continuously decreases.
It continuously increases.
It decreases at first, then increases.
It increases at first, then decreases.

answer:

There actually are simple... For metals, the thermal conductivity is mainly a function of the motion of free electrons. As the temperature increases, the molecular vibrations increase (in turn decreasing the mean free path of molecules). ... So, they obstruct the flow of free electrons, thus reducing the conductivity.

Explanation:

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
