thermal conductivity

[′thər·məl ‚kan‚dək′tiv·əd·ē]
(thermodynamics)
The heat flow across a surface per unit area per unit time, divided by the negative of the rate of change of temperature with distance in a direction perpendicular to the surface. Also known as coefficient of conductivity; heat conductivity.

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.
