Thermal Conductivity - k - is the quantity of heat transmitted due to an unit temperature gradient, in unit time under steady conditions in a direction normal to a surface of the unit area. --> else Disclaimer { document.write(''); { The alkali and alkaline earth metals in groups I A and II A are referred to as the light metals because they have low density, low hardness, and low melting points.

Thermal conductivity of air as a function of temperature can be found at James Ierardi's Fire Protection Engineering Site, Categories: Chemical properties | Thermodynamics | Heat conduction. } Thermal conductivities of the elements (data page), Wikipedia article "List_of_thermal_conductivities". Sheets of metal beyond a few micrometres in thickness appear opaque, but gold leaf transmits green light. 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. Thermal conductivity for stainless steel is 17 W/ (m K) (from the table above). However, other factors (such as atomic radius, nuclear charge, number of bonds orbitals, overlap of orbital energies and crystal form) are involved as well. Typically they are malleable and ductile, deforming under stress without cleaving. document.write('') Excel App. 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.
