What Does the Temperature Column Indicate in Thermal Conductivity Tables?

[heiroglif]

In a thermal conductivity table, what does the temperature column represent in respect to the given coefficient "K" ?

does it represent the heat capacity of the material?

Hi heiroglif,
I think this post probably should go in the Materials & Chemical Engineering Forum. But to answer your question, thermal conductivity, like many material properties, is dependant on temperature. Properties can vary significantly depending on temperature. The web page you've pointed to is just giving you the thermal conductivity at a few different temperatures. You could use a linear extrapolation to determine the thermal conductivity between two temperatures, or just find a better database that gives you properties as a function of temperature.

The temperature column in a thermal conductivity table represents the temperature at which the given coefficient "K" was measured. The coefficient "K" is a measure of the material's ability to conduct heat, so the temperature column shows the value of "K" at different temperatures. This helps to understand how a material's thermal conductivity changes with temperature. It is important to note that the temperature column does not represent the heat capacity of the material, which is a measure of the material's ability to store heat. The thermal conductivity and heat capacity are related, but they are different properties. Therefore, it is important to use the correct units and understand the difference between them when using a thermal conductivity table.
