Relatioship between density and thermal conductivity

Click For Summary
SUMMARY

The relationship between density and thermal conductivity is established as a direct correlation, where denser materials typically exhibit higher thermal conductivity. In an experiment involving concrete blocks of varying densities, it was confirmed that the denser concrete had a higher thermal conductivity. This principle is applicable across various materials, indicating that density can be a reliable predictor of thermal conductivity in many cases.

Hello!
I'm writing an essay on 'relationship between density and thermal conductivity'.
Could anyone explain to me the relationship? e.g. is it proportional or reciprocal?

I'm kind of closing to the answer by doing an experiment. I took two concrete blocks with different densities and got the thermal conductivities. The answer I got is 'denser concrete has higher thermal conductivity'.

But the real questions is, can I generalize this statement? If I can, could you give me some details why I can do so. I heard that this is applied for every material in the universe, but I'm not sure.

Thank you!
