It just gives information about the values of the element's conductivity coefficientberkeman said:I googled Heat Conductivity of Materials, and got lots of good hits. Have a look at the Hyperphysics and Wikipedia pages, and let us know if you have specific questions about that information.
Thanks a lot for your effort I really appreciate that, but How are electrons involved in transferring heat in metals?? I don't get itUltrafastPED said:Consider the Wiedemann-Franz Law: http://hyperphysics.phy-astr.gsu.edu/hbase/thermo/thercond.html#c2

These should answer your questions in a reliable way.
Heat insulators are materials that do not allow heat to pass through easily, while conductors are materials that allow heat to flow through them easily.
Some examples of heat insulators include wood, rubber, wool, and plastic. Examples of heat conductors include metals like copper, silver, and aluminum.
Heat insulators help to keep heat inside a space, making it more energy-efficient by reducing the need for external heating sources. Conductors, on the other hand, can increase energy consumption as they allow heat to escape or enter a space.
No, heat insulators and conductors have different properties that make them suitable for their respective purposes. It is not possible for one material to effectively act as both an insulator and a conductor.
The thermal conductivity and thermal resistance of a material can be measured to determine its ability to conduct or resist heat. These properties are typically measured in units of watts per meter-kelvin (W/m·K) for thermal conductivity and meters squared kelvin per watt (m2·K/W) for thermal resistance.
