Thermal conductivity of a solid is a measure of the ability of the solid to conduct heat through it. Explore about thermal conductivity , learn how to derive its equation, Know about its units and dimensions. Gases generally have low thermal conductivity , and pure metals have high thermal conductivity . For example, under standard conditions the thermal conductivity of copper is over 10 000 times that of air. Thermal conductivity can be defined as the ability of a material to transfer heat energy from a region at a higher temperature to a region at a lower temperature. The two words “ Thermal ” means heat, and “ Conductivity ” means to conduct or convey. The SI unit of the compound is watts per meter kelvin (W/ (m·K)). Suppose you are burning a potato in a campfire and accidentally touch the potato to the flame, is a real-life example of thermal conductivity . Thermal conductivity is vital for efficient heat transfer in engineering, electronics, and aerospace applications.
