Thermal ConductivityThe thermal conductivity of a material is a measure of its ability to conduct heat. It is commonly denoted by k, , or . Heat transfer occurs at a lower rate in materials of low thermal conductivity than in materials of high thermal conductivity. For instance, metals typically have high thermal conductivity and are very efficient at conducting heat, while the opposite is true for insulating materials like Styrofoam.

Thermal conductivity - Saylor AcademyThermal conductivity 1 Thermal conductivity In physics, thermal conductivity, is the , property of a material's ability to conduct heat.It appears primarily in Fourier's Law for heat conduction. Thermal conductivity is measured in watts per kelvin-meter (W·K1·m1, i.e. W/(K·m) or in IP units (Btu·hr1·ft1·F1, i.e. Btu/(hr·ftF).).
