## thermal conductivity

The rate of transfer of heat by conduction; the amount of heat per unit of time per unit area that is conducted through a slab of unit thickness of a material if the difference in temperature between opposite faces is one degree of temperature; a property of the material itself, usually represented by the letter k and called k factor.
