WebSep 9, 2024 · Heat flows in the opposite direction to the temperature gradient. The ratio of the rate of heat flow per unit area to the negative of the temperature gradient is called the thermal conductivity of the material: (4.3.1) d Q d t = − K A d T d x. I am using the symbol K for thermal conductivity. Other symbols often seen are k or λ. WebThermal conductivity, also called heat conduction, is the flow of energy from something of a higher temperature to something of a lower temperature. It is different from electrical conductivity, which deals with electrical currents. Several factors affect thermal conductivity and the rate that energy is transferred.
