Thermal conductivity - Facts, Information, and Encyclopedia Reference article |
 | | In physics, thermal conductivity, λ, is the intensive property of a material which relates its ability to conduct heat. |
| | Thermal conductivity is the quantity of heat, Q, transmitted through a thickness L, in a direction normal to a surface of area A, due to a temperature gradient ΔT, under steady state conditions and when the heat transfer is dependent only on the temperature gradient. |
| | A third term, thermal transmittance, incoporates the thermal conductance of a structure along with heat transfer due to convection and radiation. |
