1Dr. Primal (850) 410-6323 Chapter 16 Mechanisms of heat transferThermal-FluidsI2 Mechanisms of heat transfer heat can flow spontaneously from an object with a high temperature to an object with a lower temperature. heat can only be transferred between objects, or areas within an object, with different temperatures (as given by the zeroth law of thermodynamics), and then, in the absence of work, only in the direction of the colder body (as per the second law of thermodynamics). There are 3 Mechanisms of heat transfer Conduction Convection Radiation3 Conduction Conduction is the transfer of energy from the more energetic particle of a substance to the adjacent less energetic ones as a result of interactions between the particles. Conduction takes place in solids, liquids and gases.
