Properties of thermal conductivity
WebThermal conductivity is a measure of how well a material conducts heat. It is the amount of heat that is conducted through unit thickness of a material per second at a constant temperature difference across the material and is found using Equation 10.4. 10.4 where k (J s − 1 m − 1 °C − 1 or W m − 1 °C − 1) = thermal conductivity and t (s) = time.
