Thermal Conductivity Converter • Thermodynamics — Heat ...

Thermal conductivity is a property of an object to allow heat to move through it. This property is independent of the size of the object. It does, however, depend on the temperature. The higher the thermal conductivity of a material — the greater the heat transfer. For example, wool has much lower thermal conductivity than does metal, so if a ...
