Question

Relationship between density and thermal conductivity

Answer 1

Explanation:

The ability of a thermal insulation material to transmit heat in the presence of a temperature gradient is determined by its thermal conductivity. ... The results show that higher temperatures lead to higher thermal conductivities and the lower is the material density, the higher is the thermal conductivity.

Answer 2

Answer:

Thermal conductivity is a material property. It will not differ with the dimensions of a material, but it is dependent on the temperature, the density and the moisture content of the material. The thermal conductivity of a material depends on its temperature, density and moisture content.
