I don't understand why this is called "microscopic". You could take out that word and still be what it is. Or am I missing something? On the other hand, it is very useful.
The energy equation is the microscopic balance because it is derived by doing a balance on a microscopic control volume that is located at an arbitrary position within the domain, in our case within the slab. A macroscopic balance would now allow us to calculate the variation of temperature but could only get us macroscopic fluxes.
