In … See more The molecular mechanisms of thermal conduction vary among different materials, and in general depend on details of the microscopic structure and molecular interactions. As such, thermal conductivity is difficult to predict from first-principles. Any expressions for … See more In the International System of Units (SI), thermal conductivity is measured in watts per metre-kelvin (W/(m⋅K)). Some papers report in watts per centimetre-kelvin (W/(cm⋅K)). In imperial units, thermal conductivity is measured in See more The thermal conductivities of common substances span at least four orders of magnitude. Gases generally have low thermal conductivity, and pure metals have high thermal conductivity. For example, under standard conditions the thermal conductivity of See more Because thermal conductivity depends continuously on quantities like temperature and material composition, it cannot be fully characterized by a finite number of experimental measurements. Predictive formulas become necessary if experimental … See more
