Encyclopedia > List of thermal conductivities

In physics, thermal conductivity, k, is the intensive property of a material that indicates its ability to conduct heat. Image File history File links Information. ... Shortcut: WP:WIN Wikipedia is an online encyclopedia and, as a means to that end, also an online community. ... A magnet levitating above a high-temperature superconductor demonstrates the Meissner effect. ... An intensive property is sometimes defined as a ratio of two extensive properties. ... For other uses, see Heat (disambiguation) In physics, heat, symbolized by Q, is energy transferred from one body or system to another as a result of a difference in temperature. ...


It is defined as the quantity of heat, Q, transmitted in time t through a thickness L, in a direction normal to a surface of area A, due to a temperature difference ΔT, under steady state conditions and when the heat transfer is dependent only on the temperature gradient.

thermal conductivity = heat flow rate × distance / (area × temperature difference)
