This Transfer is driven by differences in temperature (a temperature gradient) and goes from locations of high temperature to those with low temperature. These temperature differences, in turn, cause mechanical stresses and strains in bodies due to their coefficient of thermal expansion, (sometimes abbreviated CTE in engineering literature) The amount of heat Transfer is directly proportional to the size of the temperature gradient and the thermal resistanceof the material(s) involved In engineering applications, there are three basic mechanisms:1.
