Question

What is thermal conductivity of air?

Answer 1

While water vapor has a higher cv than dry air, d is somewhat larger, resulting in a somewhat smaller thermal conductivity at the same temperature (at room temperature: 0.018 vs. 0.025 W/m K). With increasing temperature the mole fraction of water vapor increases, as well as the thermal conductivity of dry air

Answer 2

Warm conductivity is a material property that portrays capacity to lead warm. Warm conductivity can be characterized as "the amount of warmth transmitted through a unit thickness of a material - toward a path typical to a surface of unit territory - because of a unit temperature angle under unfaltering state conditions" .

Warm conductivity most basic units are W/(m K) in the SI framework and Btu/(h ft °F) in the Imperial framework.

Thermal conductivity of air is 0.024 W/m.K at 0°c .
