Please anyone explain it?

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

Not understanding. Explain it.

T increase K will increase.

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

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