Thermal Conductivity

018 - Thermal Conductivity

In this video Paul Andersen explains how thermal conductivity measures the ability of material to transfer heat from a hot to a cold object. The thermal conductivity of conductors is high because the heat travels through the delocalized electrons. Heat can be transferred through insulators using phonons.
