internal energy
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 as rapidly moving or vibrating atoms and molecules interact with neighbouring particles, transferring some of their microscopic kinetic and potential energies, these quantities being defined relative to the bulk of the body considered as being stationary. heat is transferred by conduction when adjacent atoms or molecules collide, or as several electrons move backwards and forwards from atom to atom in a disorganized way so as not to form a macroscopic electric current, or as photons collide and scatter. conduction is the most significant means of heat transfer within a solid or between solid objects in thermal contact. conduction is greater in solids because the network of relatively close fixed spatial relationships between atoms helps to transfer energy between them by vibration.
thermal conduction
defined by flows through a system, a flow process is a steady state of flow into and out of a vessel with definite wall properties. the internal state of the vessel contents is not the primary concern. the quantities of primary concern describe the states of the inflow and the outflow materials, and, on the side, the transfers of heat, work, and kinetic and potential energies for the vessel. the states of the inflow and outflow materials consist of their internal states, and of their kinetic and potential energies as whole bodies. very often, the quantities that describe the internal states of the input and output materials are estimated on the assumption that they are bodies in their own states of internal thermodynamic equilibrium. because rapid reactions are permitted, the thermodynamic treatment may be approximate, not exact.
