Free electrons metals conduct heat. First, let me explain why metals generally conduct heat better than other solids do. Electron conduction (dominant). Delocalised electrons carry energy. What are some factors that influence a metal’s electrical conductivity? In metals, free electrons act as highly mobile carriers of thermal energy. The two properties often correlate in metals (good electrical conductors tend to be good heat conductors too, because free electrons carry both charge and thermal energy), but they can diverge in other materials. When a temperature gradient exists, the higher-energy electrons from the hot region diffuse into the cold region and transfer their excess kinetic energy through collisions with other electrons and the lattice. Alkali metals (K, Na, Rb) and Noble metals (Cu, Ag, Au) have filled shell + 1 outer s-electron. . They're not exactly free in metals either, although a pure electron gas can be heated too. , one Kelvin degree) with the volume held constant. jprbyqnypleqlogcdkvoevpteqhdidmlgapgiacvznxjliqba
