Noun
thermal conductivity (plural thermal conductivities)
(physics) A measure of the ability of a material to conduct heat, often denoted k, λ, or κ.
Although related to the thermal conductivity of a material used in an insulation product, R and U-values are dependent on the thickness of the product. Source: Internet
Application of heat to a spot in superfluid helium results in a flow of the normal component which takes care of the heat transport at relatively high velocity (up to 20 cm/s) which leads to a very high effective thermal conductivity. Source: Internet
Applications Protection Cryogenics Kevlar is often used in the field of cryogenics for its low thermal conductivity and high strength relative to other materials for suspension purposes. Source: Internet
At higher (viscous flow) and lower (molecular flow) pressures, the thermal conductivity of air or any other gas is essentially independent of pressure. Source: Internet
Atomically, the thermal conductivity of a system is determined by how atoms composing the system interact. Source: Internet
At the atomic level, there are no simple, correct expressions for thermal conductivity. Source: Internet
