The most common example of pure conduction is heat flow in opaque solids such as the brick wall of a furnace.

With increase in temperature free electron movement will be promoted in amorphous solids there by k increases.

T increase K will increase.

Not understanding. Explain it.

But in amorphous solid, there are weak bonding, so that no chance of free electron movement, then how it is increasing?

An amorphous solid is any noncrystalline solid in which the atoms and molecules are not organized in a definite lattice pattern. Such solids include glass, plastic, and gel. Solids and liquids are both forms of condensed matter; both are composed of atoms in close proximity to each other.

Then why the thermal conductivity decreases with increase in temperature?
Siddharth P. said:

Non-metals are generally referred as insulators or poor conductors of heat; so their resistance decreases with increase in temperature and hence the conductivity increases as they are inversely proportional.
