In the temperature range above ambient, λ for nearly all pure metals falls with increasing temperature. All values are from published tables, but can't be taken as authoritative. 700 . 1050 . … Thermal Conductivity of Fluids (Liquids and Gases) In physics, a fluid is a substance that continually deforms (flows) under an applied shear stress. Generally speaking, dense materials such as metals and stone are good conductors of heat, while low density substances such as gas and porous insulation are poor conductors of heat. Sp. Its unit is Watt per meter per Kelvin: W.M-1.K-1. In the below periodic table you can see the trend of Thermal Conductivity.
