What is the difference between thermal conductivity and

Thermal conductivity of a material is defined as the rate of heat transfer through a unit thickness of the material per unit area per temperature difference. The thermal conductivity is ability of the material to conduct the heat.The higher value of thermal conductivity indicates good heat conductor and low lower value of thermal conductivity indicates poor heat conductor.
