WebHeat energy is conducted from the hot end of an object to the cold end. Conduction in solids The atoms of a solid are held together by chemical bonds. The atoms are fixed in …
Conduction is the process by which heat is transferred from the hotter end to the colder end of an object. The ability of the object to conduct heat is known as its thermal conductivity, and is denoted k. Heat spontaneously flows along a temperature gradient (i.e. from a hotter body to a colder body). For example, … Ver más On a microscopic scale, conduction occurs within a body considered as being stationary; this means that the kinetic and potential energies of the bulk motion of the body are separately accounted for. Internal energy diffuses … Ver más Splat cooling Splat cooling is a method for quenching small droplets of molten materials by rapid contact with a cold surface.
