Water does,however; not have the greatest thermal conductivity of liquids.Some liquids and gels have been designed to have thermal conductivities over 6.0 W/m-K (10x that of water).These liquids and gels are known as thermal interface materials and play a very important role in electronics.For further information,visit:Thermal Conductivity of Materials and Chemical ElementsDefinitionsPropertiesMechanismIntroductionStructureThe thermal conductivity of most liquids and solids varies with temperature.For vapors,it also depends upon pressure.In general Most materials are very nearly homogeneous,therefore we can usually write k = k (T).Similar definitions are associated with thermal conductivities in the y- and z-directions (ky,kz),but for an isotropic material the thermal conductivity is independent of the direction of transfer,kx = ky = kz = k.The thermal conductivity of gases is directly proportional to the density oSee more on nuclear-power.netThermal conductivityThermal conductivity 1 Thermal conductivity In physics,thermal conductivity,is the ,property of a material's ability to conduct heat.It appears primarily in Fourier's Law for heat conduction.Thermal conductivity is measured in watts per kelvin-meter (WK1m1,i.e.W/(Km) or in IP units (Btuhr1ft1F1,i.e.Btu/(hrftF).).Multiplied by a temperature difference Thermal Conductivity of Metals,Metallic Elements and Alloys275 rows·Propane - Thermal Conductivity - Online calculator,figures and tables showing thermal
