In conduction, the heat flow is within and through the body itself. In contrast, in heat transfer by thermal radiation, the transfer is often between bodies, which may be separated spatially. Heat can also be transferred by a combination of conduction and radiation. See more 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 … See more Writing Fourier's law can also be stated as: The reciprocal of conductance is resistance, See more Splat cooling Splat cooling is a method for quenching small droplets of molten materials by rapid contact with a cold surface.
