Compare heat transfer by conduction in a metal rod vs a wooden rod of the same dimensions when one end is heated.

Heat transfer by conduction depends on how easily a material lets heat move through it, which is described by its thermal conductivity. If two rods have the same size and you apply heat to one end, the rate at which heat flows along each rod is higher when the material has a larger thermal conductivity. Since metal typically has a much higher thermal conductivity than wood, the metal rod will carry heat from the heated end to the rest of the rod much faster. Wood, with its low conductivity and more insulating structure, resists heat flow and remains comparatively cooler near the heated end for longer. Because of this, the metal conducts heat much faster, and the wooden rod conducts it more slowly.
